Hazardous Location AND Overheating Electronics? We Have You Covered!

Here in Ohio, we like to think we know a lot about the weather. Did you know there are more than 4 seasons? Heck, we have at least two Winters, and then a Pre-Summer, Spring, Summer, Heat is still coming – make it stop season, and Fall. Don’t forget the construction season where the lovely orange cones and barrels bloom on every major roadway, and then we also like to throw in brood weeks for the cicadas every now and then. Yeah, we get a full gambit of weather and the past week has brought out some heat. I know this isn’t just Ohio, we get calls from around the globe of atmospheric conditions that have caused issues within control panels. Some of these panels are in areas where the No Smoking sign is more than just a suggestion to better your health.

That’s right, there are areas in manufacturing facilities that are governed by the standard due to a variety of conditions resulting in what is known as Hazardous Locations. NFPA and UL have a list of standards breaking these down into separate Classes, Divisions, and Temperature Classes. If you want all the details, the NFPA code is around 908 pages, cover to cover. The Classified UL mark shown below is one way of knowing that a product has been tested to these stringent standards and is okay to use in clearly marked environments.

UL Classified Markings

EXAIR offers Cabinet Cooler Systems that will meet these stringent standards and keep your enclosures cool in order to keep your production up and running. The top three tiers that we meet are:

  • Class I Div 1, Groups A, B, C and D

EXAIR’s Cabinet Coolers: No Maintenance, Simple Installation, Many Years of Trouble Free Operation!

I recently had the pleasure of working with a customer that was looking to expand their production capacity. They were duplicating an existing line due to an increase in demand and needed another Cabinet Cooler. The previous unit, HT4325-24VDC, had been installed over 20 years ago and was still functioning without any issues. This was long before he had started working with the company and they were unable to locate any order history with EXAIR to determine the appropriate model size to order so they quickly uninstalled it to help identify which model they had been relying on all these years.

HT4325 Cabinet Cooler – over 20 years old!!!

They installed the cooler and auto-drain filter that comes with the kit. The only maintenance they’ve had to complete for the system is periodically changing the filter element. The Cabinet Cooler has no moving parts to wear out and requires little to no maintenance so long as it is supplied with clean, condensate free compressed air.

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.

These systems are available with cooling capacities of anywhere 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, contact an Application Engineer today and we’ll see to it that this summer your cabinets remain cool!

Summer is Coming: EXAIR Cabinet Coolers Save Your Electrical Cabinets from Overheating

The pool is open, the garden is tilled, it must mean summer is coming. This year, I’m gearing up for a hot one. My love for spicy food is already well documented here on the EXAIR Blog, and this year it’s going to be the hottest one yet! In the garden for this year we have Purple Ghost Peppers, “regular” Bhut Jolokia (Ghost peppers), White Moruga Scorpion, Purple Ghost Scorpion, Bhutlah Scorpion, and a selection of “milder” peppers and other veggies for when I’d rather not melt my face off while eating. Needless to say, you should proceed with caution when eating salsa at my house. It’s going to be heating up in my kitchen at the same time your electrical cabinets also begin to overheat. Not to worry, EXAIR has the tools you need to keep things cool.

Understanding your Cabinet Cooling Investment

You can make a better decision choosing your cabinet cooling product by understanding the total cost of your investment and the operating cost associated with each style. Today we will compare EXAIR Cabinet Cooler systems and a refrigerant based enclosure air conditioning system.

How will EXAIR’s Cabinet Cooler system benefit you? I will help you understand your investment, installation, maintenance and operating costs for both EXAIR Cabinet Coolers verses a refrigerant based conditioner. The importance of understanding these costs will not only help you realize the return on your investment but will also give you the confidence knowing you made the best decision for you and your company. We will compare EXAIR’s model 4325 (NEMA 12) with a 1700 BTU capacity to a similar coolant based air conditioning unit.

The initial investment for the EXAIR model 4325, 1700 Btu/hr. Cabinet Cooler system at 2021 list pricing is $809 and will have an estimated life of 20 years ($40.45/yr). The initial cost for a refrigerant based A/C with similar Btu/hr is $3777 and an estimated life of 5 years ($751.58/yr). EXAIR’s Cabinet Cooler runs on compressed air and has no moving parts which provides a long product life . It is built for industrial, dirty, extreme temperature, heavy duty and remote locations.

Installation of the EXAIR Cabinet Cooler when installed according to manufacturers recommendation will take approximately 1 hour (estimating $65/hr) while the enclosure a/c will take up to 3 hours or more. There is no worrying about what position it was on the shipping truck, no time to allow the oil to drain back into the refrigerant compressor and no huge window to cut out of your enclosure to mount within. Again the edge goes to EXAIR Cabinet Coolers with less hassle and downtime. If we use that same operating lifetime the Cabinet Cooler system will require $3.25/yr and the refrigerant unit will require $39/yr for installation.

As mentioned earlier that EXAIR Cabinet Coolers do not have moving parts thus reducing or practically eliminating any maintenance or downtime. The refrigerant cooler will average 4 hours of downtime for cleaning and checking for refrigerant leaks. You will also experience downtime to replace filters and refill refrigerants when required. There will be drain lines to maintain for the condensate that will accumulate. EXAIR wins again having no downtime or costs for replacement parts. A refrigerant unit can require 4 hours per year of maintenance to provide its full five years of usefulness. Again using $65/hr there are zero dollars per year in Cabinet Cooler system maintenance compared to $260/yr for the refrigerant unit.

If we assume that the systems run an average of 5 hours per day, 5 days per week and 9 months per year we can calculate the cost of operating each style of cooling device. We know that it costs $0.025/1000 cu. ft of air. When put into our equation it shows that the EXAIR Cabinet Cooler system has an annual operating cost of $338. The coolant based a/c unit operated on electric at a rate of $0.0955/KWH for an annual operating cost of $56.38 giving the edge to this unit.

The total cost of your investment, installation, maintenance and operating costs for the EXAIR Cabinet Cooler is $382 per year while the coolant based a/c is $1106.96 per year giving a fast return on investment for the EXAIR 4325 Cabinet Cooler system and a very long period of keeping your electronics protected and running effectively.

EXAIR Cabinet Coolers are a low cost, reliable way to cool and purge electronic control panels. Not only is the EXAIR product more economical to purchase, maintain and install but they also provide a longer life as they incorporate a vortex tube to produce cold air. The EXAIR system also maintains NEMA 12, NEMA 4 and NEMA 4X panel integrity and are UL Listed and CE certified by independent laboratories.

EXAIR Application Engineers are ready to answer all your questions and help you determine the correct cabinet cooler size specifically for your needs.
