What is an EXAIR Cabinet Cooler®?

EXAIR Cabinet Coolers are a low cost, reliable way to cool and purge electronic control panels. They provide air conditioning for the electrical enclosures, eliminating electronic control downtime due to heat, dirt and moisture! These panel cooling systems for enclosures incorporate a vortex tube to produce cold air from compressed air - with no moving parts. The compact Cabinet Cooler is an easy to use air conditioner that can be installed in minutes through a standard electrical knockout. NEMA 12, 4 and 4X Cabinet Coolers that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels.

EXAIR's new Side Mount Kits for NEMA 12, 4 and 4X Cabinet Coolers offer convenient mounting to the side of an electrical enclosure. Watch the Cabinet Cooler Video.

Why EXAIR Cabinet Coolers? When the electronics inside a control cabinet overheat, the machine can shut down due to tripped overloads and breakers or heat damage to the circuit boards. Unreliable cooling methods such as fans, heat exchangers, refrigerant air conditioners, and heat pipes are prone to failure as a result of mechanical wear, and clogged filters. EXAIR Cabinet Coolers provide cold air for large and small control panels and are maintenance free. They have no moving parts to wear out. All Cabinet Coolers are UL and ULC Listed and have a five year “Built To Last” warranty.

Heat Can Stop Your Machines
It happens when you least expect it. High temperatures can cook the electronics that control your machines, resulting in erroneous readings, trip-outs or fried circuit boards. Cooling the electrical cabinet can eliminate these problems, but how will you do it?

Heat Exchangers and Heat Pipes
These have serious limitations when it comes to summer time heat. In many cases, the temperature of the hot plant on a summer day is close to that inside the enclosure. There is not enough difference in temperature for a decent heat exchange.

Refrigerant Panel Air Conditioners
These coolers are expensive, take almost a day to install, and are prone to failure when dust and dirt clogs the filter. Vibration from machinery contributes to component failures and loss of freon. Life expectancy for most compressors is rated at 2.5 years of continuous operation. Average replacement cost for a bad compressor is $750 plus installation. Often, a floor drain is not readily available for the condensation tube.

EXAIR Cabinet Coolers
Our compressed air operated Cabinet Coolers are the low cost solution. NEMA 12, 4 and 4X models are available that are very compact and mount in just minutes through an ordinary electrical knockout. Thermostat control limits compressed air use by operating the Cabinet Cooler only when the temperature inside the enclosure reaches critical levels.

Heat exchangers, heat pipes and refrigerant coolers all have filters that can clog. Left unattended, mechanical failure of the cooler is likely. And, the expensive equipment in the electrical enclosure can malfunction, overheat and shut down the entire machine or process. EXAIR Cabinet Coolers have no moving parts to wear out and do not require constant monitoring. All models are UL Listed and available in a large number of styles and cooling capacities.
