During the warmer weather, electrical panels will start to feel the “heat.”  Freon-based coolers can be less effective in higher ambient conditions; and opening the electrical panels to have a fan blowing air inside creates a dangerous hazard.  To reduce loss in production and premature equipment failures, it is important to keep electrical components cool.  The EXAIR Cabinet Cooler Systems are an easy choice for consistent, long-lasting results. 

Cabinet Coolers are powered by Vortex technology, which uses compressed air to generate cold air flow.  They do not have any moving parts to wear.  They do not require any Freon or a refrigerant compressor that can fail.  They require very little to no maintenance to keep them operating for a long time.  EXAIR offers a variety of types and cooling capacities to work inside some of the toughest of conditions.  We range from 275 to 5,600 BTU/hr (80 – 1641 Watts) of cooling power.  They are easy to install, and EXAIR has several ways that can help you start using our Cabinet Cooler Systems. 

At the start, we do have a Cabinet Cooler Sizing Guide to help determine the total heat load.  This can be sent to us for calculations and recommendations.  We also have a Cabinet Cooler System Calculator on our website if you wish to tackle this yourself. 

EXAIR does an excellent job of helping our customers purchase a Cabinet Cooler System.  We use multiple methods to make sure that you are getting the correct information and the best out of our system.  So, if it is your first time ordering a system, here are some areas to help you quickly and easily install your new unit. 

We have our Installation Guides on our website for instructions and troubleshooting.  If you are more visual, like I am, we also have informal videos to give some tips and tricks.  Here is a list: 

How to install a Cold Air Distribution Kit

How to install Side Mount Kit

The Electronic Temperature Controller upgrade

Using the Cabinet Cooler Sizing Guide

Measuring internal and external air temperatures

Installing the Dual Hardware Kit for Dual Cabinet Coolers

Installing NEMA 4/4X Cabinet Coolers

Connecting the Thermostat to the Solenoid Valve

Resetting the thermostat

If you still have any questions, you can reach us by phone at 800-903-9247 or contact us through Chat.  An Application Engineer is waiting to help you.  For our U.S. customers from now until the end of August 2026 with qualified purchases, you will receive an AC Sensor for free, a $77.50 value, as a promotional item.  As I mentioned above, EXAIR has a number of ways to assist you from start to finish.

Press Release: Dual Hazardous Location Cabinet Cooler Systems Protect Large Electrical Enclosures in Classified Areas

Published on by John BallLeave a comment

EXAIR’s Dual Hazardous Location Cabinet Cooler® Systems provide a powerful, maintenance-free solution for protecting large electrical enclosures in hazardous environments. Designed for classified areas, including Class I Div 1, Groups A, B, C, and D; Class II Div 1, Groups E, F, and G; and Class III, these high-capacity cooling systems prevent sensitive electronics from overheating while eliminating the need for costly air conditioners or panel fans. With cooling capacities up to 5,600 Btu/Hr, Dual Hazardous Location Cabinet Coolers are ideal for oversized control panels, motor control centers, and other electrical enclosures exposed to explosive gas or combustible dust atmospheres.

                Dual Hazardous Location Cabinet Cooler Systems use two engineered Cabinet Coolers working together to evenly distribute cold air throughout large enclosures, maintaining safe operating temperatures for critical electrical components. The systems are UL tested for hazardous locations and preserve the enclosure’s integrity by mounting through standard electrical knockouts. Each system includes an automatic drain filter separator to prevent moisture from entering the enclosure, while optional electronic temperature controls are also available. With no moving parts to wear out and no refrigerants to maintain, the systems provide long-lasting, reliable protection in the harshest industrial environments.

                Dual Hazardous Location Cabinet Cooler Systems are part of EXAIR’s complete family of Cabinet Cooler® Systems, offering solutions for NEMA 12, 4, 4X, and ATEX-rated enclosures ranging from 1,000 to 5,600 Btu/hr. Whether cooling a small control panel or a large electrical enclosure in a classified area, EXAIR provides engineered cooling solutions for virtually any enclosure cooling challenge.

                If you require assistance with sizing, EXAIR does have a Cabinet Cooler Sizing Guide to fill out for us to calculate the total heat load.  For our U.S. customers, we are offering a promotion.  You will receive an AC Sensor, a $77.50 value, for free as a promotional item from now until the end of August 2026 with a qualified purchase of our Cabinet Coolers. If you have any questions or need more information about our Cabinet Coolers, an Application Engineer can assist you.

Informal Video: How to Change the HEPA Filter on an EXAIR Heavy Duty HEPA Vac

Published on by John BallLeave a comment

The HEPA filter inside the Heavy Duty HEPA Vac System has a 99.97% efficiency at 0.3 micron. It will contain very fine dust inside the drum and not back into the atmosphere. When the filter gets plugged, you will need to change it. In this video, I go through the steps for installing a new HEPA filter.
