Cabinet Coolers - Stop electronic control downtime

Supplier: Compressed Air Australia

EXAIR Cabinet Coolers are a low cost, reliable way to cool and purge electronic control panels. They 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 12, 4, and 4X (IP54 and IP66) models that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels.

The vortex tubes incorporated in EXAIR Cabinet Coolers are constructed of stainless steel. The wear, corrosion and oxidation resistance of stainless steel assures long life and maintenance free operation. All EXAIR Cabinet Coolers are UL Listed and CE compliant.

EXAIR Cabinet Coolers are available with or without thermostat control. The continuous coolers are recommended when constant cooling and a constant positive purge are desirable. The thermostatically controlled systems save air by activating the cooler only when internal temperatures approach critical levels. The adjustable thermostat is factory set at 35°C. Thermostatic systems are recommended where heat load fluctuates and continual purge is not required.

EXAIR manufactures special NEMA 4, 4X and 12 Cabinet Coolers suited to specific environmental requirements:

High Temperature Cabinet Coolers for ambients of 52° to 93°C are available. Internal components can withstand high temperatures (like those near furnaces, ovens, etc.).

Non-Hazardous Purge Cabinet Cooler Systems 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 of air through the cooler. When the thermostat detects high temperature, it energises the solenoid valve to pass full line pressure to the Cabinet Cooler, giving it full cooling capability.

Dual Cabinet Cooler Systems up to 5600 Btu/hr. (1411 Kcal/hr.) capacity are available. They are ideal for applications where the heat load is extremely high.

Type 316 Stainless Steel NEMA 4X Cabinet Coolers are suitable for food service, pharmaceutical, harsh and corrosive environments, and other applications where 316SS is preferred. Capacities up to 5600 Btu/hr. (1411 Kcal/hr.) are available.
