for ambient temperatures of 52 °C to 93 °C (125 °F – 200 °F). Internal components can withstand high temperatures (like those near furnaces, ovens, etc.).

Non-Hazardous Purge Cabinet Cooler Systems

Non-Hazardous Purge Cabinet Cooler Systeme are ideal for dirty areas where contaminants might normally pass through small holes or conduits. Under normal conditions, the NHP Cabinet Cooler Systems provide a slight positive pressure in the enclosure by passing 1 SCFM (28 SLPM) of air through the cooler, when solenoid valve is in the closed position. When the thermostat detects high temperature, it energizes the solenoid valve to pass full line pressure and volume of compressed air to the Cabinet Cooler, giving it full cooling capability.

Selecting the right Cabinet Cooler. Please use our Cabinet Cooler Sizing Guide

Here Cabinet Cooler Sizing Guide – Select the right Cabinet Cooler
To determine the correct model for your application, it is necessary to determine your requirement.

EXAIR Cabinet Coolers are available with or without thermostat control. The continuous coolers (Model series 4200 and 4700) are recommended when constant cooling and a constant positive purge are desirable. A thermostatically system saves air by activating the cooler only when the internal temperature is critical.

All Exair Cabinet Cooler Systems contain a 5 micron Automatic Drain Filter for the compressed air supply and a Cold Air Distribution Kit to circulate the cold air throughout the enclosure.

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?

Hitze kann Ihre Maschinen zum Stillstand bringen. 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.

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.
