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?

Es besteht eine hohe Schockgefahr, wenn die Schalttafeltür geöffnet wird und ein Ventilator heiße, schmutzige Fabrikluft auf die Elektronik bläst.

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 Cooler

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.

Model NEMA 4/4X small = Model 4608 + 4608SS

Model NEMA 4/4X large (except Model 4608 + 4608SS)

NEMA 12 small = Model 4008

NEMA 12 large (except Model 4008)

Electronic Temperature Control

The digital Electronic Temperature Control (ETC) provides precise temperature control for your electrical enclosure. It can accureately maintain a constant temperature that is slightly under the maximum rating of the electornics, permitting just enough cooling for the electronics without going so cold as to waste compressed air. The LED readout of the ETC displays the internal temperature of the electrical enclosure (°C or °F) that is constantly being monitored by a quick response thermocouple. The control activates the solenoid valce (included) when the temperature setting is exceeded. The polycarbonate plastic enclosure of the ETC is suitable for NEMA 12, 4 and 4X environments.

Side Mount Kits EXAIR´s Side Mount Kits make mounting on the side of an electrical enclosure possible when there is limited space on the top or side (NEMA 4 and 4X Cabinet Cooler Systems must be mounted vertically). The Side Mount Kits maintain the NEMA rating of large and small NEMA Type 12, 4 and 4X enclosures. They mount in a standard electrical knockout (1-1/2″ NPS). Side Mount Kits for NEMA 12 Cabinet Cooler Systems have an aluminum construction. Those for NEMA 4 and 4X Cabinet Cooler Systems are Type 303 or Type 316 stainless steel.
