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.

EXAIR Cabinet Cooler Eases Maintenance Schedule, Replaces A/C System for Beverage Manufacturer

CC_Actionshot

During a recent visit with our distributor in Lima, Peru I had the pleasure of visiting a beverage manufacturing facility to discuss EXAIR’s Cabinet Coolers. They have several panels throughout the facility with A/C units installed. A lack of adherence to scheduled maintenance was causing the filters to clog and restrict the cooling power of the A/C unit. Due to staffing issues, their maintenance department was very thin and regular maintenance items were getting missed.

When the filters would clog, the panels would overheat and stop production. Their solution was to open the panel up and blow fans on them, forcing even more dust into the enclosure. In their search for an alternative solution, they came across EXAIR’s Cabinet Cooler Systems and reached out to our distributor. The A/C unit that was installed on the panel had a capacity of 800W (2,728 Btu/hr). EXAIR offers a 2,800 Btu/hr system from stock that matched up perfectly for them.

They installed a Model 4340-24VDC Nema 12 Cabinet Cooler System with 24VDC thermostat control and removed the A/C system. With no moving parts and no refrigerants, there’s absolutely no maintenance required. Just set it and forget it! The Cabinet Cooler has kept the electronics inside at 95°F, preventing any potential for heat related shut downs. Since all Cabinet Coolers must be installed onto a sealed enclosure, there is no need for filters on the enclosure to prevent dirty ambient air from entering. They’re now working to replace each of the A/C units in the facility with an EXAIR Cabinet Cooler.

EXAIR manufactures Cabinet Coolers for any industrial environment. Cabinet Coolers maintain Nema 4, Nema 4X, and Nema 12 integrity on the enclosure and are also UL Listed and CE Compliant. For applications that may be in a classified area, the Hazardous Location Cabinet Cooler has been approved by UL for use in Class 1 Div 1 – Groups A, B, C, and D; Class II Div 1 – Groups E, F, and G; and in Class III areas. Cooling capacities as high as 5,600 Btu/hr can be achieved with one of our Dual Cabinet Cooler Systems.

Stop wasting precious time maintaining you’re A/C systems, or dealing with heat related shutdowns and get a Cabinet Cooler on order today. Fill out the sizing guide online, and one of our Application Engineers will be in touch to provide you with the most suitable model for your application. Act fast, the current Cabinet Cooler promotion expires at the end of August!
