Selecting The Right Cabinet Cooler®

With or Without Thermostat Control EXAIR Cabinet Coolers are available with or without thermostat control. The continuous coolers (Model 4200 and 4700 series) are recommended when constant cooling and a constant positive purge are desirable. The thermostatically controlled systems (Model 4300 and 4800 series) save air by activating the cooler only when internal temperatures approach critical levels. The adjustable thermostat is factory set at 95°F (35°C). Thermostatic systems are recommended where heat load fluctuates and continual purge is not required.

A dangerous shock hazard exists when the panel door is opened to let a fan blow hot, dirty shop air at the electronics.

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.

Environmental Considerations
NEMA 12 (IP54) Cabinet Coolers (dust-tight, oil-tight) are ideal for general industrial environments where no liquids or corrosives are present.

NEMA 4 (IP66) Cabinet Coolers (dust-tight, oil-tight, splash resistant, indoor/outdoor service) incorporate a low pressure relief valve for both the vortex tube and cabinet air exhaust. This valve closes and seals when the cooler is not operating, to maintain the integrity of a NEMA 4 enclosure.

NEMA 4X (IP66) Cabinet Coolers (corrosion resistant) offer the same protection as NEMA 4, but are constructed of 304 stainless steel for food service, pharmaceutical and corrosive environments.
