4 Applications that Benefit from LCP DX-Based Liquid Cooling

Guest Contributor, Herb Villa, Rittal

Liquid cooling of IT equipment, now at the row level instead of for an entire white space, is gaining momentum in the distributed data center world, where the demand for efficiency in cooling higher density racks is making IT professionals rethink their reliance on traditional methods. Various liquid cooling technologies – direct-to-chip, immersion, direct expansion and others – are winning favor in the different IT spaces. Why? Because they bring heat removal closer to the equipment, require little if any changes to infrastructure, and are easy to scale as demand grows; when you need to add more racks, additional cooling capacity is achieved with the cooling systems supporting increased IT enclosures.

Liquid cooling is especially advantageous for small and medium-sized businesses that have on-premise servers mounted in one or more enclosures. Many of the IT professionals supporting these organizations are forced to put these in some remote, out-of-the-way space within the building, assuming (wrongly) that as long as the building’s HVAC system has a vent terminating in that room, cooling the equipment won’t be a problem.

But we’ve seen that “comfort cooling,” which is the job of a facility’s HVAC system, isn’t adequate for server rack cooling and the demands of heat-generating IT equipment. Those demands are non-negotiable: precise temperature and humidity control, and proper airflow to get the heat away from the equipment.

Focusing on just a few different market sectors can illustrate the demands of the new IT environment. Hospital & healthcare, schools, factory floor, distribution centers are all examples of the types of organizations and facilities often forced to utilize spaces never intended to support the climate control needs of IT equipment: unused offices, janitors’ closets, corners of basements, etc. And because all rely on data to run their businesses, they’re all at risk of system failure because they aren’t addressing the critical climate needs of their IT investments.

Enclosure Climate Control in Hospitals

Data is critical in ensuring quality patient care and the smooth, efficient performance of even the smallest healthcare facilities. Hospitals, clinics and physician practice groups rely on IT equipment to store and transfer data among departments, achieve operational efficiency and maintain compliance using enterprise resource planning (ERP) systems. Without proper temperature, humidity and airflow control, the IT equipment that processes and stores necessary data could fail, and the cost of downtime and potential lost data is immeasurable.  There is also extremely limited space to place these systems; after all, the main business of a hospital is patient care, not IT.  Especially today in the midst of a global pandemic, healthcare facilities must maximize space for their patients, not their IT appliances.

Data Center Cooling in Education/School Campuses

What happens when a school’s “comfort cooling” system can’t keep up with all the heat being generated by the server room’s IT equipment (if they are lucky enough to even have such a space)? These systems are intended to keep humans comfortable, not maintain the precision and optimal air flow needed to remove heat generated by the IT equipment. Schools rely on IT equipment to help maintain productivity, organize data, and reduce time and effort of work that would otherwise be manual. Servers and processors enable insights that help administrators allocate the right resources to the right areas at the right time, connect campuses and departments, and speed communication between students, teachers, administrators and parents. And as with the healthcare sector, COVID-19 has placed enormous demands on bandwidth and compute capability as school systems have become virtual classrooms supporting remote learning applications and programs. This means more equipment, more heat, and less available installation space.

Server Rack Cooling in Manufacturing

Manufacturing facilities represent some of the most uncontrolled environments in which to place IT equipment. Wide temperature ranges, dust, debris, moisture and corrosive elements are all enemies of smooth factory floor operations, and because there is often no dedicated IT room (or at least one designed for IT), the risk of equipment degradation and failure is very real. Manufacturing organizations rely heavily on manufacturing execution systems (MES) and ERP systems for visibility into all aspects of the supply chain and production, and for seamless integration between the shop floor and Billing, Sales, Operations, HR and other departments.

Climate Control Units in Distribution

Distribution warehouses are notorious for having subpar climate control: they’re often either too hot or too cold; when air conditioning is running, cold air is “dumped” to the floor and doesn’t mix with warmer air near the ceiling (and the opposite situation when the heat is running); air flow throughout the building is almost impossible to control; and air leaks from the inside to outside and vice versa are common. Imagine, then, the effect of a poorly controlled climate in a small room where heat is being generated.

Like manufacturing, warehousing and distribution rely on up-to-date information about inventory, customers (through a CRM tool), fleet management, marketing, shipping and more. When equipment is compromised by temperatures that are too high (and in some cases too cold), all the data that’s used to ensure optimum facility and system performance is at risk for failure.

The best solution for cooling racks for these types of organizations is one that’s similar to a building’s own AC – one that uses direct expansion (DX). Heat removal is achieved with a compressor / condenser refrigeration cycle to reach and maintain a setpoint temperature and humidity level but that is designed to work at the cabinet (sometimes called enclosure) level.

Rittal’s DX-based solution (part of the Liquid Cooling [LCP] family of products) is ideal for businesses, like those above, that have “mission-critical” data needs but less-than-ideal data room options. The close coupled LCP DX 20kW provides a single or multiple IT enclosures with up to 20kW heat removal capacity, available in both closed loop rack and open loop inline options. Some of the benefits of this solution include:

  • A small footprint, making it appropriate for nearly any location within the building
  • Precise temperature and humidity control that responds to varying equipment heat loads
  • Local climate control – airflow is provided to one or more cabinets in a closed system, or cooling to the entire space in an open airflow configuration
  • Simple maintenance – tool-less fan replacement, easy-to-access electrical connections and remote notification of all operational parameters
  • Redundancy – up to 8 units can be interconnected, with coordinated air flow, alarms, and time-of-day operation
  • Reduce the need for a dedicated room to support IT equipment.  With proper planning and physical security, it is possible to place these systems out on the floor or shared space. The costs to build and maintain a dedicated IT room are eliminated

Today, every organization, no matter the size or industry, relies on optimum IT equipment performance in order to meet its ongoing operational demands. If yours is putting rack cooling needs at the mercy of your building’s HVAC system, the risk of system downtime is very real, and the potential cost to operations significant. The best protection against system failure is to utilize IT cabinets with liquid cooling capabilities that offer precise control of temperature, humidity and airflow – all critical factors when it comes to ensuring that your organization’s work is never disrupted.

Understanding Hygienic Zones

Guest Contributor: Rittal

In any facility that processes food, beverages or pharmaceuticals, cleanliness is the absolute top priority. To avoid product contamination and bacteria growth, these facilities have strict cleaning requirements that include the use of aggressive cleaning agents and high-power spray wash downs. In order to protect the critical components for these processing lines, enclosures, accessories and equipment must be specified properly and meet facility requirements including IP69K,

Because of the variations in processes and practices in each section of these facilities, the cleaning and equipment requirements will vary by each hygienic zone. The infographic below defines the Basic, Medium and High Hygiene zones as well as outlines what specific considerations you should keep in mind for specifying systems and enclosures.

The Enclosure Testers

Guest contributor: Rittal LTD

Rittal’s innovative VX25 enclosure was recently put through its paces by technicians from the Schaper Group. 

Their observations on the new enclosure are notably around improved operational efficiencies and increased productivity. These offer interesting insights for other operators, and indeed anyone who has the final say on enclosure technology.

Sometimes, it’s the smallest things that make all the difference.  For Eugen Franzen, the team leader for mechanical installation at Controller Steuerungstechnik GmbH, part of the Schaper Group, it was an almost nondescript detail that won him over.

fri1820569100 Rittal enclosure testers

“The hole counting on the new frame sections means we can now pinpoint precisely where enclosure mounting parts should go,” he says.

This tiny, time-saving addition means operators can mount support rails or cable clamp rails at identical heights across all their enclosures, easily and with confidence. “Previously, we often had to revisit such details, which always involved extra work that we no longer have to worry about.” says Eugene.

It’s a welcome productivity improvement for Schaper Group teams, who like many in the sector, juggle fit-to-burst order books and high time/cost pressures, with the ever-present lack of specialist workers.

“All in all, we currently have seven vacancies in the manufacturing department alone and could hire trained applicants on the spot,” explains Nils Mentrup, technical manager at Schaper Steuerungstechnik GmbH.   Automated solutions that deliver a higher output with fewer trained staff offer Nils some relief.  But clearly new components and systems that save time during assembly also boost efficiency in manufacturing operations.

At the company’s cutting-edge manufacturing plant in Herford, Germany, everything is state of the art, meticulously planned and perfectly organised.

The facility, which features numbered wiring areas, was built in 2009 more than doubled in size in the last year.  Seventy workers manufacture control and switchgear solutions of various sizes at the site. “Thanks to the facility’s expansion, we now have enough space to produce several large systems 30 to 40 metres in length at once,” explains Nils.

They have just completed their first control systems using Rittal’s new VX25 enclosure.

“Its predecessor, TS 8, was a flawless enclosure,” recalls Nils. “That’s why we were pleasantly surprised that Rittal had evidently put a lot of thought into many different potential improvements when it devised the VX25.”

His attention has been on the reduced number of mounting parts and the positive impact this has had in terms of storage: “You see it straight away because storage is less of an issue now – both in our central warehouse and the parts warehouses for the individual projects that we set up directly at our workstations.”

Greater stability

The stability of the VX25 also meets the team’s approval.

“The enclosure itself is more stable now – that’s one of its major benefits,” say Eugene.

This is particularly apparent in the new gland plates.

When fitters are expanding enclosures they have to repeatedly go inside them. “In the past, the gland plates were often somewhat bent as a result, meaning we had to carry out reworking,” remembers Eugene. This is now a thing of the past, which of course adds to the overall time saving.   Added to which, there is the enclosure flooring’s design: “The frame is now designed so that there is no space between it and the gland plate. Back in the day, we often had problems with a screw falling down the gap,” he explains.

The new hinges allow the team to remove the enclosure doors without levering any hinge pins.  Eugene advises: “Even if we don’t plan to carry out machining on one of our Perforex machining centres, we usually take the enclosure doors off because it makes wiring so much easier.”

This particularly applies to larger switchgear, where wires need to be installed across multiple enclosures. “The time saved in assembly and dismantling can be anything up to one minute or more for each enclosure,” he adds.

“We also no longer have to wonder which rail goes where because with the VX25, the rails fit on both the vertical and horizontal frame parts and can be fitted from the side or the rear.” This means the team can now screw on a rail from the back, even if the mounting plate has already been fitted in the enclosure.

“In the past, if we ever forgot about the rail – which is an absolute must for some switchgear built to UL – we had to take the mounting plate apart or at least tip it forwards.” This is no longer the case, making life a lot easier for the team, and extends to fitting mounting components or side/rear panels.

“During assembly work, we always used to have two cordless screwdrivers that were equipped with the appropriate screw bits – now we only need one,” says Eugene.  The principle of one-person assembly has also won the team leader over.  “I can simply attach the rear panel at the top and it stays securely in position until I’ve tightened the screws.”

For any team, switching to new technology or products can create issues.  “At the start, most people are sceptical whenever things change, but we found the switchover to be quick and seamless,” says a delighted Nils.

This smooth transition is helped by the VX25 conversion assistant – a web-based tool that enables customers to simply convert parts lists from projects planned using the TS 8 into parts lists for the VX25.  Teams simply drag and drop their old parts lists onto the designated site, upload them as Excel files, and download the new parts lists once converted.

Even 3D engineering plans generated by Eplan Pro Panel can be converted without virtually no manual intervention. “Now that the first two large systems with the new enclosure are nearly finished, we have a good handle on how the conversion works,” says Nils.

Fast assembly

There are other time-saving aspects to dealing with Rittal.  For example, the company’s 24-hour delivery service.

“Nowadays, most units that we use in our systems take a relatively long time to deliver – that’s not the case with Rittal enclosures, which are always delivered the day after we place the order.” says Nils.

“We’re going to spread the word among our customers and we’re certain that they’ll soon see the benefits, too.”

System Perfection – VX25

Guest contributor: Rittal Ltd.

The VX25 is the first large enclosure system capable of meeting the technical requirements of Industry 4.0 to perfection, while at the same time ensuring faster, more productive assembly. This Rittal innovation is the result of our tireless striving for MORE: more simplicity, more speed, more benefits. More than 25 registered property rights confirm the reputation Rittal has earned as the leading innovator in enclosure technology.

vx25

1. Efficient processes

End-to-end, accurate, validated 3D data ensure a high level of planning confidence from the outset. A plausibility check in the Rittal Configuration System facilitates fast, error-free configuration of products and accessories.

2. Reduced complexity

In the VX25, we have managed to successfully replicate all the functions of the predecessor model TS 8 with far fewer accessory parts, while creating new functions and adding value. A consistent 25 mm pitch pattern across all levels and between enclosures has helped to significantly reduce the number of individual parts – for example, 40 per cent fewer punched sections/rails.

3. Improved access

The VX25 is accessible from all four sides, because components can now also be fitted to the outer mounting level from the outside. This saves 30 minutes compared with conventional assembly.  The same applies to the new option of installing mounting plates from the rear.

4. Simple interior installation

Fast assembly is facilitated by complete symmetry on all vertical and horizontal enclosure sides. The installation depth can also be increased by 20 mm with optional accessories. Multiple mounting plates can also be installed in one enclosure.

5. Tool-free installation

The simple, tool-free assembly of the handle system reduces assembly time by 50 percent. Similarly, doors can also be fitted and removed without the need for tools.

6. More functions

Even enclosure accessories can now be built into the base. For example, baying brackets and cable clamp rails can be installed there, and cables can be simply and efficiently retained and secured via the punched sections. Not only does that save time and money, it also boosts safety.

Understanding Edge Computing

Guest Contributor: Rittal

With the growth of Artificial Intelligence or AI machinery that takes in information, learns and makes decisions, Edge computing will become not only necessary, but mandatory. The need to process data at the source to ensure acceptable performance will continue to grow with AI and AI will only be able to grow as fast as data storage capabilities grow. edge_923x340

 

To ensure acceptable performance of data processing at the source and reduce latency, Edge Computing will become more important. Formerly only used by large corporations, Edge is now being utilized by small to medium businesses that need services such as peer-to-peer networking, mobile signature analysis, mobile data acquisition, and AI. In the case of machinery, this puts Edge Computing outside of a traditional data center environment and the need for small portable data centers with cooling will spread. According to a recent IDC study by 2020, more than 70% of infrastructure-centric partners will become involved in IoT and Edge Deployment.

image-for-edge-of-possibility (1)

Rittal started in the Industrial Market which is geared towards machinery and outside applications including dust/moisture proof NEMA 12 enclosures here in the U.S. in the 1980’s. Rittal continues to lead the world in global enclosure solutions that include all types of environments. From dirty and extreme temperature fluctuations, to typical clean and climate-controlled environments, Rittal has the right solution for you.

Edge Computing Defined

Edge computing houses data processing capability at or near the “edge” of a network. Usually, servers are contained in a micro data center, with as few as one or two enclosures. Data which is mission-critical, such as a system fail, is captured and available in real-time on site. Edge computing is valuable in capturing bandwidth intensive and latency sensitive data for analysis, lowering operating costs and improving energy efficiency. Lower priority data can be sent to the cloud or to a remote data center.

In Edge Computing, client data is processed at the periphery of the network, as close to the source of the originating data as possible. Companies are moving toward edge computing, driven by economics and efficiency. In edge computing architecture, critical data is processed at the point of origin via a server in close proximity to the output, for immediate and easy access. Data which is not as time sensitive is sent to the cloud or a data center for longer term storage, analysis or compliance record keeping.

The practice of edge computing alleviates the load on network resources. By processing data at the source, only the data required for transfer is shifted to a remote data center or cloud. The amount of data transmitted reduces the strain on bandwidth, and by specifying criteria, data can be sorted to provide key analytics at the site and to push non-essential data to the center.

With IoT and the proliferation of smart devices, edge computing becomes particularly valuable when massive data pushes would overload a data center. When monitoring enclosure temperature for example, it is unnecessary to upload data which will only be valuable to the operations manager in real time. If this data has historical value, it can be pushed to a data center at a later time, or when bandwidth is not at a premium. With edge computing, this illustrates one of its major benefits.

Since edge computing reduces response time to milliseconds, adjustments at the site level can be made almost simultaneously. However, the cloud and data centers will not be made obsolete, since the long term storage capacity is still needed.

Although edge reduces latency and improves accessibility, security concerns and configuration architecture must be addressed. With the distributed architecture of an edge security system, points are increased for system attack. Security breaches and infectious malware may be introduced at vulnerable points.

With the configuration of the device, secure default passwords need to be placed on each device, and vigilance applied to the updating of software to avoid infiltration of malware. Even with the potential points of vulnerability, the overwhelming advantage of the decreased latency and the instant data accessibility overwhelming support the use of edge computing to improve efficiency.

Balancing the Value of Air-to-Air and Air-to-Water Heat Exchangers

Guest contributor: Eric Corzine, Product Manager Climate Control, Rittal

Heat exchangers provide highly efficient cooling for electrical components. As energy costs increase, they are getting more consideration by system designers. Before making a design decision between air-to-air and air-to-water heat exchangers,  it is important to weigh installation considerations and use-cases. Here, we have provided an overview of each technology to help you determine which can best impact your equipment and your bottom line.

Air-to-Airsirair

Air-to-air heat exchangers are the most common type of exchangers. They work by utilizing the difference between the hotter internal temperature of an enclosure and the cooler, ambient air temperature. Engineers can implement air-to-air exchangers in a variety of industrial environments, including food and beverage, waste and wastewater, and automotive.

Air-to-air exchangers can utilize existing airflow patterns, through convection or forced air, and do not require additional accessories or equipment. The technology can utilize the airflow within an enclosure or can connect to existing ductwork and HVAC systems.

There are some limitations to air-to-air heat exchangers, particularly in the climates they could be installed. For instance, if the difference between indoor and outdoor temperatures is to great then the effectiveness of the exchangers can be significantly reduced. Recent technology upgrades, however, have made air-to-air exchangers functional even in climates that reach temperatures of -13°F.

These factors make air-to-air heat exchangers useful in applications where plumbing for liquid cooling would be difficult to install, and where existing air flow patterns and equipment layout allow for effective cooling. Often, this means situations with moderate thermal loads. HVAC engineers can install them quickly as well, which reduces setup time and costs. However, they are still less efficient compared to air-to-water exchangers because air is not as effective at transferring heat as water.

Air-to-Waterairwaterdownload (6)

Air-to-water heat exchangers use the same principle of temperature differential to provide heating or cooling, however, they alter the temperature of air by forcing it across water coils.

Because of the efficient heat transfer capabilities of water, they can help reduce energy use and utility costs significantly. This is especially useful in situations with large thermal loads, such as IT mainframe applications or an automotive manufacturing environment where water is already available.

One of the drawbacks of air-to-water heat exchangers is the need to pipe water to the unit. The technology requires plumbing and a reliable water supply or recirculation system, which often means pumps, valves, and other accessories.

These plumbing concerns often mean higher installation costs, so engineers need to balance the initial cost with the expected savings over the lifetime of the exchanger. Overall, air-to-water exchangers are useful for high-demand, energy intensive applications.

Making the Right Choice

It is important to consider the right exchanger for your specific climate control situation. The ultimate decision will balance installation and operational costs, target cooling capacity and thermal loads.

Air-to-air exchangers can get up and running quickly and engineers can integrate them into many different kinds of applications easily. Air-to-water exchangers deliver better efficiency and can suit more energy-demanding applications, but they require plumbing and water supplies, which may not always be available. The ultimate choice, then, should consider these factors and engineers should thoroughly research both types of exchangers to understand which one will best suit their application.

Decentralized Control Systems to the Rescue

Guest contributor,  Bob White, Kollmorgen

Less Cabling, Smaller controls cabinet, Less heat…wow, that’s all great stuff.  I can achieve this all with a decentralized solution? Absolutely – and even more! 

Decentralized Control Architecture means shifting the motion control drives from the crowded cabinets, and moving them near to the motors – out on the machine where the action is.  Immediately you can see that this can reduce the size of the controls cabinet, moving all of those drives out onto the machine – but how do I see these other advantages?

Decentralized ArchitectureIt’s not JUST about moving the drives out onto the machine, near or integrated with the motors, but also how you design your entire control system.  Think about a conventional Centralized Control Architecture – all of your drives, power supplies and other I/O are jammed into a large cabinet and cables are run to each motor – and since we are talking conventional, this likely means multiple cables (power and feedback for each motor). So in a decentralized solution, the motor, feedback and fieldbus communication needs to be run through a single cable, and the control architecture  allows communications to function over the fieldbus loop.

So thinking about it that way, with an 8 axis machine – Control cabinet 5 meters from the initial motor, and subsequent axes 3 meters apart – this adds up quickly to almost 250 meters of cabling (Power and Feedback) using a centralized approach.

Centralized vs Decentralized ImageImagine now – A decentralized solution, drives located within a meter of the motor they are driving – you cut cabling down to a mere 35 meters!  Do the math – an 86% reduction!  Throw in extended I/O and your savings jumps to almost 90%  SO – Point 1 – Substantially reduced cables cost – not just from the mere reduction in cable length, but in reduced costs associated form cable management trays and even the labor to run the cables.

But there’s more (or do I mean less).  Smaller cabinet, less electronics, means less heat to dissipate – electronics usually don’t like the heat, so they tend to get some cool air, provided by some nice air conditioning system.  Less heat, less need for an expensive air conditioning unit, AND less energy consumption.

One other element not so readily apparent with a good decentralized design – flexibility!  Designing with a decentralized drive architecture in mind from the start opens up new possibilities.  This allows more flexibility in modularization.  We’ll cover this modularization concept in a follow on blog topic next time…

All of these advantages help the OEM build a more efficient machine, with less components, reduction in assembly time, and more flexibility in design – improving the marketability of the machine.  End users enjoy the lower cost of ownership and increase reliability – and potentially space savings on their factory floor.

Industrial Enclosures Protect Components in Harsh Environments

Guest contributor: Steve Sullivan, Rittal Training Manager

Industrial enclosures face harsh conditions. From blazing to frigid temperatures, to dust, oil, dirt, airborne corrosives and liquids. Industrial engineers know that the manufacturing environment poses a multitude of challenges to the integrity of the control panel infrastructure.

 Environmental protection of the control panel infrastructure is never simple. Determining factors in the selection of an industrial enclosure can include the most extreme conditions. The key to selecting the superior enclosure is evaluating the harshest environment possible, and specifying an enclosure that can withstand any setting.

Foreign substances

Environment elements that can affect the performance of the control panel include the picture-2
penetration of foreign substances (water, dust, dirt, oils, etc.). The delicate electronic equipment housed inside the enclosure can fail with even minimal exposure to external substances.

The Rittal TS 8 combats the ingress of these substances with a four-point latching system and a foamed-in-place gasket system. This forms a continuous barrier around the enclosure skin ensuring a gap-free seal. This creates a superior seal and memory retention to block out the challenges of any environment.

Temperature

The control panel infrastructure faces temperature challenges on two fronts. First, internal temperature is affected by the heat generated from the operation of control panel devices. The external or ambient temperature also affects the enclosure and the operating control panels.

Fully compatible with the TS 8 is Rittal’s line of cooling solutions for both enclosure based and room based thermal management. With 30% to 50% of energy costs attributed to cooling systems, Rittal designs maximum cooling efficiency into each solution: CRAC, in line/in row, chillers, pipe installations, water distribution cabinets or water heat exchangers.

The delicate dew point balance between the load temperature and the ambient temperature is maintained, preventing damaging condensation of the control panels.

Washdown

When washdown of enclosures is required, the control panels must be protected. Exposed to harsh chemical cleansers, high pressure and/or heated water and frequent cleaning can break down some sealing systems. Rittal’s impervious seal guards the vital control panel components from the most stringent cleaning procedures.

Corrosive Elements

Whether an enclosure is in an indoor or outdoor environment, corrosion can be a factor in the breakdown of the enclosure’s durability. Outdoor factors such as sun, snow, salt or chemicals can damage the exterior of some enclosures. Acids, solvents, alkalis, oils and industrial chemicals can threaten an enclosure housed on the factory floor.

Rittal engineers designed a three-step painting process to combat any environmental abuse. Similar to the process used in the automotive industry, an electrophoretic dip-coat primer is applied, followed by a two-part primer nano-coat and final powder coat. This provides a finished external barrier on the TS 8 for any climate, interior or exterior.

Enclosure material construction

A variety of materials have been used for industrial enclosures. The stainless steel 316 construction of the Rittal TS 8 has been proven to be impervious to the most corrosive environments and superior to lesser steel or powder coated materials. Stainless steel 316, combined with the three-step finish has proven durability in the most extreme conditions.

The environmental protection offered by the Rittal TS 8 has been field tested in more than 10 million installations, in industries like oil and gas, mining, pulp and paper, food and beverage and life sciences.

LED Lighting System Designed Exclusively for Industrial Enclosures

Guest contributor: Steve Sullivan, Rittal

Rittal has set a new standard with the LED compact system light. The innovative LED technology shines into every corner of industrial enclosures, from the roof to the floor. No other enclosure light on the market today provides the lumen power…up to three times the luminous flux of the next closest competitor.

Rittal accomplishes this with intelligent lighting tailored to the geometry of the enclosure. Light is dispersed through a special optical cover with Fresnel structure, in two designs for precise lighting. The cover rotates easily, for adaptive light distribution. With enormous intensity, from 900 to 1200 lumens, the light provides brilliant illumination.

The LED system light matches the footprint of fluorescent lighting on the market, and simplifies specification requirements for the market. It is low maintenance and easy on energy as well.led_light

Rotating connectors support installation, even in the most confined spaces. With a swivel option, the light direction can be changed to spot-illuminate any part of the enclosure. Through-wiring is plug and play, and it can be additionally equipped with a socket for available electricity wherever it’s needed for maintenance work. Daisy chain multiple units, up to 15 direct wire or 10 with socket. Variants with integral motion detectors eliminate the need for installing separate door-operated switches.

The LED Compact lighting is safe, with an extra-low voltage range. As with all Rittal products, the product matches global standards, and the LED system light is suitable for wide range voltage from 100-240 V (AC) and 24 V (DC). It is fully certified by E76083 requirements.

Rittal makes installation simple. It is perfectly integrated to the TS 8. Fast, tool-free assembly on a latching hook system uses a 25 mm pitch pattern of holes to simply latch and secure. Optional screw-fastening is also available, or opt for complete flexibility with magnetic attachment to freely position the light anywhere in the enclosure.

The light may be fitted horizontally or vertically with no loss of space in the enclosure. Existing rails and sections can simply be covered. Lights with motion detectors are equipped with a rotating LED board as standard, allowing the direction of the light to be perfectly adapted to any installation situation.

The newly released LED system light brings optimum illumination of the entire enclosure. It can be attached a variety of ways: with clip, screw or magnet for a configuration to brighten every application. It can be installed in just two minutes, and the cable connection rotates a full 90°, not just in one direction like other lights.
