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.

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.
