A dirt and dust resistant EXAIR NEMA 4X Non Hazardous Purge Cabinet Cooler® System provides a slight positive pressure in the enclosure to keep contaminants from entering small holes or conduits. NEMA 4X 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). They are a low cost, reliable way to cool and purge electronic control panels. EXAIR Cabinet Coolers incorporate a vortex tube to produce cold air from compressed air - with no moving parts. The compact Cabinet Cooler can be installed in minutes through a standard electrical knockout. NEMA 4X (IP66) Cabinet Coolers (dust-tight, oil-tight, splash resistant, corrosion resistant, indoor/outdoor service) are ideal for general industrial environments where no liquids or corrosives are present. All Cabinet Coolers are UL Listed and CE compliant.

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.) 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.
