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.

NEMA Rating

The first step to solving your overheating problem is
to identify the NEMA integrity your enclosure will
require. At right is an explanation to help you
determine which NEMA integrity Cabinet Cooler
system we should ship to you.

Thermostat Control

The thermostat control systems are the most efficient way to operate a Cabinet Cooler. They save air by activating the cooler only when internal temperatures approach critical levels. Thermostat controlled cooler systems
are the best option when experiencing fluctuating heat loads caused by environment or seasonal changes.The standard thermostat control systems include an adjustable thermostat factory set at 95°F (35°C).

ETC Electronic Temperature Control

EXAIR’s digital ETC (Electronic Temperature Control) provides precise temperature control for your electrical enclosure. It can accurately maintain a constant temperature that is slightly under the maximum rating of the electronics, 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 (°F or °C) that is constantly being monitored by a quick response thermocouple. The control activates the solenoid valve (included) when the temperature setting is exceeded. h e polycarbonate plastic enclosure of the ETC is suitable for NEMA 12, 4 and 4X environments. (Cabinet Cooler not included.)
