Stop the Overheating Alarms from Your Electrical Cabinets this Summer

I’ve already documented my penchant for insanely hot foods in a previous blog post about my participation in a hot wing competition. Over the years, I’ve grown a few different varieties of super-hot peppers in my garden that’s led to my love for all things fire. In years past I’ve been limited to the varieties of peppers that I can find at the local nurseries.

This year I decided to take things a step further. I purchased a variety of both pepper and tomato seeds online and decided to grow them from seed, allowing me to pick and choose each type that I wanted in the garden for this summer. While it’s been a bit of a learning process and we’ve had a few fallen soldiers thus far, things are beginning to come together. It’s been a fun way to look forward to this year’s growing season.

It seems strange writing this while there is snow on the ground here in Cincinnati, but spring is right around the corner. I don’t know about you, but I quickly see past spring and can start to feel the warm summer weather.

Once again, as summer’s hot temperatures approach,  so do those seasonal temperature alarms from your electrical enclosures. Increased temperatures lead to heat related problems in your electrical panels. With summer coming along before you know it, the time is now to get a solution in place before it becomes an issue.

EXAIR’s Cabinet Cooler Systems were designed specifically to rectify these issues within your facility. Utilizing Vortex Tube technology, the Cabinet Cooler produces cold air from an ordinary supply of compressed air. This cold air keeps the enclosure free of debris and moisture and is easily installed in minutes through a standard electrical knockout. Here is a short video that shows just how simple it really is.

The Cabinet Cooler Systems are available with Nema 12 (IP54) ratings and are also available in Aluminum, 303 Stainless Steel, and 316 Stainless Steel construction for Nema 4/4X (IP66) rated enclosures. For systems that are not able to be mounted on top of the cabinet, we also have Side Mount Kits available in Aluminum, 303 Stainless, and 316 Stainless. This year, EXAIR also introduced a new line of Hazardous Location Cabinet Coolers for use in classified areas.

These systems are available with cooling capacities from 275-5,600 Btu/hr. To make things much easier for you, we offer a Cabinet Cooler Sizing Guide that will allow us to recommend the most suitable model for your cabinet. With a few quick measurements, we’ll be able to determine the exact heat load that we’ll need to dissipate and offer you a quick and easy solution.

If you experienced heat related issues on electrical panels last year, or just want to talk about spicy food and gardening, contact an Application Engineer today and we’ll be happy to help.

Hazardous Location Cabinet Coolers

Last year was a big year for EXAIR’s Cabinet Cooling product line, in November  we launched our first Hazardous Location Cabinet CoolersEXAIR has always been a leading supplier in compressed air-based Cabinet Coolers, now we have expanded on that to work in the most high-risk conditions.

When a Hazardous Location Cabinet Cooler is used in conjunction with a purge system, they will keep electrical equipment at the desired operating temperature to protect and lengthen the lifetime of pricey controls and power supplies.

Hazardous Location Cabinet Cooler

 

Electrical equipment can cause explosions in certain atmospheres. Equipment used in areas where explosive concentrations of dusts or vapors may exist must be equipped with special wiring and other electrical components for safety purposes. Hazardous (classified) locations such as these might exist in aircraft hangars, gasoline stations, paint-finishing locations or grain bins. EXAIR’s Hazardous Location Cabinet Coolers have been approved and tested by UL for use in the following areas:

classified_cULus_360x283
UL Approved and Tested

Class I Div 1&2 – Groups A, B, C, and D

  • Class I Areas refer to the presence of flammable gases or vapors in quantities sufficient to produce explosive or ignitable mixtures. Class I Div 1 will have ignitable concentrations of flammable gases present during the course of normal operations. This is level of approval is one that differentiates the EXAIR Hazardous Location Cabinet Coolers from much of the competition. Class 1 Div 2 areas will have flammable gasses or vapors present only in the event of an accident or during unusual operating conditions.

Class II Div 1&2 – Groups E, F, and G

  • Class II areas are locations in which combustible dust may exist. The end user shall avoid installation of the device in a Class II environment where dust may be readily disturbed from the exhausts of the Hazardous Location Cabinet Cooler. Any dust formed in the vicinity of the cooler must be cleaned regularly.

Class III

  • Class III areas are locations that will have ignitable fibers or flyings present. This is common within the textile industry.

The Cabinet Cooler also carries a temperature rating of T3C, meaning it cannot be installed near any materials that could auto-ignite at temperatures in excess of 320°F.

The Hazardous Location Cabinet Cooler is available in (8) different cooling capacities ranging from 1,000 Btu/hr – 5,600 Btu/hr. The Cabinet Cooler is the best solution for protecting your sensitive electronics from heat, dirt, and moisture. With Nema 4/4X systems available, the Hazardous Location Cabinet Coolers will keep the cabinet cool without compromising the integrity of the enclosure.

If you’ve got an electrical cabinet installed within a hazardous location, fill out the Cabinet Cooler Sizing Guide and allow an EXAIR Application Engineer to determine the most suitable model for you.

EXAIR’s Hazardous Location Cabinet Coolers are engineered for use with purged (not included) electrical enclosures. The HazLoc Cabinet Coolers are not purged and pressurized control systems and should not be relied upon nor used in place of a purged and pressurized controller. They are meant for use in conjunction with a purged and pressurized control system. These systems have been approved and tested by UL for use in the following areas:

Class I Div 1&2 – Groups A, B, C, and D

  • Class I Areas refer to the presence of flammable gases or vapors in quantities sufficient to produce explosive or ignitable mixtures.

Class III

  • Class III areas are locations that will have ignitable fibers or flyings present. This is common within the textile industry.

The Cabinet Cooler also carries a temperature rating of T3C, meaning it cannot be installed near any materials that could auto-ignite at temperatures in excess of 320°F. For a comprehensive list and description of all of the various Classified areas, check out the UL website.

The Hazardous Location Cabinet Cooler is available in (8) different cooling capacities ranging from 1,000 Btu/hr – 5,600 Btu/hr. The Cabinet Cooler is the best solution for protecting your sensitive electronics from heat, dirt, and moisture.
