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.
