With 12 million units sold around the globe, the TS 8 modular enclosure is established as the worldwide-standard. As businesses grow and enclosure needs evolve, many customers are turning to a variety of accessories to scale their solutions. 

These five accessories for lighting, power distribution, viewing and operating, climate control, and assembly are the most popular customizations design engineers and facilities managers are utilizing to maximize their investments. 

1 – For Lighting: LED Compact Lighting System

The Rittal LED Compact Lighting System is a safe, energy-efficient, extra-low-voltage interior lighting solution that delivers full coverage to all corners of the enclosure.  

Enterprise-ready and suitable for voltages ranging from 100–240 V (AC) and 24 V (DC), the LED system can be installed tool-free with clips that connect to a latch-in hook pattern—though optional screw fastening is also available. Magnetic installation is another option, for free positioning within the enclosure. Whichever assembly option you choose, motion detectors or door-operated switches for hands-free illumination are also available.  

2 – For Power Distribution: RiLine Busbar System 

In many regions around the world, busbar systems are the predominant solution for managing power needs now, and in the future. For engineers not familiar with the technology, the RiLine copper busbar system provides reliable power distribution and requires less panel modification, contact points, and wiring work. Busbar systems save space and time for panel builders and offer more contact hazard protection than other cable management options. 

3 – For Viewing Windows and Operating Panels: WKDH Deep Hinged Window Kit 

The Deep-Hinged Window Kit is ideal for installing a viewing window where access to components mounted behind it is required. It is designed to protect HMI displays and components mounted on enclosure panels from wash-downs, rain, snow, sleet, dirt, and dust. The window depth allows for extra-deep pushbuttons (~2”/50mm) and comes with a full-size drill template for easy mounting.  

4 – For Climate Control: TopTherm Filter Fans 

Simply and efficiently manage air flow in your enclosure with filter fans designed for tool-free, snap-in mounting and installation. The TopTherm filter fan’s new diagonal fan technology creates greater pressure stability and constant airflow when installed, even with a contaminated filter mat. This new technology also allows air currents to spread diagonally from the fan, promoting even circulation throughout an enclosure. 

5 – For Base Assembly: Flex-Block Base/Plinth System 

Save assembly time with high-strength plastic corner pieces that clip together base/plinth components. With this system, enclosure transport is uncomplicated, both empty and fully-configured, by removing the base/plinth trim panel. Plus, cable management is straightforward and efficient, saving space for enclosure configuration.

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.

Improving Arc Flash Prevention and Safety

Guest contributor: Steve Sullivan, Rittal

Working among the electrical components in an enclosure comes with inherent risks. The power in any one enclosure can range from 2kw up to 200kw depending on the power density. One of the most common and dangerous risk is an arc flash (or flashover).

When an explosive release of energy erupts from a phase-to-phase or phase-to-ground arc fault the results range from devastating to deadly. This air to ground electrical explosion is a critical concern for engineers and managers who are charged with the safety of their employees.

The Destructive Force of an Arc Flash

The dangers from an arc flash are all too well known. Five to 10 of these accidents occur every day in the United States. When metal expands and vaporizes at the fault, it causes extreme heating of the air, upwards of 10,000°C/18,032°F. The concussive pressure wave can knock personnel off their feet, the ultraviolet light flash can cause blindness, the sound blast, deafness and the molten metal and heat can cause second and third degree burns. The specific death toll has been estimated to be up to 1-2 people per day worldwide.

An arc flash can be the result of unsafe work procedures, accidental contact or more systemic problems such as corrosion of components and connections or insulation failure. Arc flash prevention should be incorporated into any application from the beginning of the design process.

Minimizing Arc Flash Exposure

Design and retrofit approaches can limit exposure by using components installed outside the enclosure to permit qualified personnel in personal protective equipment (PPE) to service equipment inside without opening the enclosure door. Interface flaps and window kits permit data retrieval, equipment monitoring or routine maintenance to be performed from outside. Collapsible fold down shelves be raised for use with laptops and monitoring equipment. External data pockets can hold wiring diagrams, operation manuals and other documents.

Rittal and Arc Flash Protection

Sometimes components must be accessed from inside the enclosure. Rittal’s arc flash solution is designed to keep high and low voltage equipment within the confines of their own respective enclosures. Low voltage enclosures house equipment that is used for programming, data acquisition and system adjustment.

High voltage components are isolated within their own disconnect enclosure, while line side power is segregated within the power isolation enclosure. A partition wall acts as a barrier to high voltage line side power. Rittal’s interlocking door system ensures that the high voltage enclosure cannot be opened while the disconnect switch is in “ON” position.

For additional safety, all interlocked doors and master door must be closed in order to re-energize the enclosure. This removes potential for accidental contact with the inline power when the disconnect enclosure is put in a safe power-off position, and locked and tagged out.

Minimizing exposure to line side power can help protect personnel from accidents. A qualified person wearing PPE and following appropriate safe work practices can perform visual inspections and tasks, such as diagnosis, testing, troubleshooting and voltage measurement with the door open even when the main enclosure is energized.

Rittal offers an unlimited choice of low-voltage and high-voltage enclosure combinations. More important than saving down time caused by having to power down the whole system to service, the Rittal arc flash solution helps to decrease the risk personnel being exposed to arc flash-related injuries.

Safety is always your priority, so download Rittal’s Arc Flash and How to Prevent it whitepaper for the first step towards arc flash prevention.

Considerations for Industrial Enclosure Cooling

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

Data Centers and server racks run hot. Protecting the technology backbone of your company means managing air flow, temperature, energy consumption and cooling technology.

Rittal, the world’s largest enclosure manufacturer and a leader in thermal management of electrical, electronic and IT equipment, offers some important guidelines to ensure your equipment stays in optimum condition. The following tips are based on decades of practical experience in the use of enclosures climate control solution in industrial environments. By ensuring sufficient planning and maintenance guidelines are in place, control cabinets and electronic enclosures can be last longer and be more energy-efficient.

7 Considerations for More Efficient Enclosures

1. Devices and electrical components must be installed in the enclosure in accordance with the manufacturer instructions. Storage space for necessary documents and circuit diagrams should also be taken into account during the planning phase.

2. When arranging the components in the enclosure, verify that the cooling air flows from top to bottom. You can ensure this in the planning stages by properly routing the air flow away from the electronic components. When roof-mounted units are used, particular attention needs to be paid to the air flow from blowers built into electrical components. The use of air duct systems is advisable in the case of roof-mounted cooling units

Proper Enclosure Heat Dissipation

3. There should be sufficient space for air to flow between the parts and electrical components.

4. Air intake openings of climate control components must not be obstructed by electrical devices equipment or cable ducts. With all climate control solutions, the cold air should always be routed close to drive units. This is where the greatest heat losses occur. This arrangement ensures that the cold supply air from the climate control solution optimally cools the drive units without losses.

Air intake design for cooling enclosures

5. Internal temperatures of the enclosure should always be set to +35◦C. There is no technical justification for setting the temperature any lower. If the temperature inside the enclosure is any lower, condensation will be significantly increased.

6. Institute a systematic cleaning cycle. As most climate control components are used in industrial environments external filters of the climate control must be maintained to ensure long-lasting operation.

7. Ensure the correct filters are used for the industry application.

PU Filter for Industrial Enclosure Cooling

In heavily dust-laden atmospheres, PU filters should be used and replaced on a regular basis. Cooling units with Ri Nano coating typically do not need a dust filter.

Metal Filter for Enclosures

If the air is oil-contaminated, use metal filters. These separate the oil condensate from the air and can be cleaned with appropriate detergents

Textile Enclosure Lint Filter

In the textile industry, the use of lint filters is recommended.

Fiber Mat Filter

Chopped fibre mat filters are not suitable for cooling units.
