It’s that time of year again… Cabinet Cooler season!!! With the temperatures ramping up, so are our promotions! Now through the end of August, with the purchase of any Cabinet Cooler System, you will receive a free AC Sensor. The EXAIR Model 7929 AC Sensor offers a reliable method for non-contact verification of voltage presence. When voltage is detected, the sensor’s tip emits a bright red glow accompanied by an audible alert, ensuring users can easily confirm power to their electrical devices. This versatile tool is suitable for testing various components, including wall receptacles, switches, fuses, and junction boxes. Additionally, it can detect electricity through insulation, making it effective for identifying breaks in power cords and wires.

Now for the Cabinet Coolers!!! EXAIR’s Cabinet Cooler employs Vortex Tube technology to generate cold air from standard compressed air supplies, effectively keeping enclosures free from debris and moisture. Installation is straightforward, taking only minutes through a typical electrical knockout. The Cabinet Cooler Systems come with Nema 12 (IP54) ratings and are offered in various materials, including Aluminum, 303 Stainless Steel, and 316 Stainless Steel, suitable for Nema 4/4X (IP66) rated enclosures. For installations where top mounting is not feasible, Side Mount Kits in the same materials are available. This year, EXAIR has broadened its product range by introducing Hazardous Location Cabinet Coolers and ATEX Cabinet Coolers, catering to customers with specific ATEX compliance needs.

These systems offer cooling capacities ranging from 275 to 5,600 Btu/hr. To simplify your selection process, we provide a Cabinet Cooler Sizing Guide that helps us recommend the most appropriate model for your cabinet. By taking a few quick measurements, we can accurately assess the heat load that needs to be managed and present you with a straightforward solution.

From ancient times humans have sought ways to cool themselves down, from the invention of the manual fan in ancient times to the modern A/C systems that are used to cool down entire buildings. Anymore these days there is a cooling system for just about anything; gaming PC’s have there own cooling system, personal fans that mist water for cooling down people, climate-controlled boxes for artifacts in museums, etc. But what about your electrical cabinets in your facility? Electrical cabinets that overheat can cause expensive shut downs and lead to unsafe operations where the doors are left open with fans blowing in. When it comes to electrical cabinets there are two well-known ways that are used to cool down electrical cabinets which are fans and A/C units. But there is a third option you can go with which is EXAIR’s Cabinet Coolers.

Cabinet Coolers are compressed air powered cooling units that utilize a source of compressed air and vortex tubes to cool down enclosed areas. But why would you choose a Cabinet Cooler over an A/C coolant driven system? Each system has pros and cons that can be weighed against each other.

A/C Coolant Driven Systems:
Pros:
Can produce higher cooling loads effectively

Cons:
Expensive up front
Constant maintenance

Cabinet Coolers:
Pros:
Inexpensive upfront cost, lower lifetime cost
No moving Parts / No actual maintenance

Cons:
Smaller range for effective cooling

A/C Units operate in most cases using a chemical known as Dichlorodifluoromethane more commonly referred to as Freon (Freon is a registered trademark of Chemours Co.). By compressing and decompressing the liquid you can cause significant temperature drops in the surrounding air that can be blown into an area. This process requires a lot of moving parts that will eventually wear out and need to be replaced at a cost. Cabinet Coolers don’t have that issue, since they use vortex tubes there are no moving parts to wear out. As long as you provide clean dry air to a Cabinet Cooler the system will run indefinitely. Another thing to keep in mind is that although Dichlorodifluoromethane is a safer version of the older CFC’s , the chemical is not completely safe. Freon can be harmful to the environment as it can breakdown ozone, and due to its its density it will displace oxygen and can cause rapid suffocation.

Cabinet Coolers use compressed air, air which we breath and is all around us. So, no hazards with its energy source.

Lastly, although A/C units are cheaper to run they are much more expensive upfront cost and upkeep cost. This means in the long run it is actually cheaper to use a Cabinet Cooler because it does not have any upkeep cost for maintenance and repairs, along with being much cheaper to begin with.

EXAIR’s Cabinet Coolers are currently on promotion – receive a free AC Sensor with the purchase of any Cabinet Cooler.
