EXAIR Cabinet Coolers are available with or without thermostat control. Indeed, the choice between with or without thermostat control largely depends on the specific cooling needs and environmental conditions of your application.

Continuous Operation Coolers (Model 4200 and 4700 series): Ideal for applications requiring constant cooling and a continuous positive air purge.

Thermostatically Controlled Systems (Model 4300 and 4800 series): Efficiently manage cooling by activating only when internal temperatures near critical levels, saving air and energy. These systems are perfect where the heat load fluctuates and a continuous purge isn't necessary.

Moreover, every EXAIR Cabinet Cooler System comes with a 5 micron Automatic Drain Filter for clean compressed air and a Cold Air Distribution Kit to ensure effective air circulation within 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 stainless steel for food service, pharmaceutical and corrosive environments.

EXAlR Cabinet Cooler Systems include a 5 micron automatic drain water and dirt filter. This filter is critical for protection of electronics from water and dirt in the compressed air line. If oil is present in the compressed air supply, the addition of a coalescing (oil removal) filter, such as EXAlR Model 9005, is recommended.

Cabinet Cooler Systems provide a 54°F (30°C) temperature drop from supply air temperature when the inlet pressure is 100 PSIG (6.9 BAR). Elevated inlet temperature will produce a corresponding rise in cold air temperature and reduction in cooling capacity. Low air pressures will also reduce the cooling capacity.

For a continuous operating Cabinet Cooler, relative humidity inside the enclosure stabilizes at 45%. No moisture condenses inside the enclosure. (The enclosure must be sealed to prevent condensation.)

The kit includes a length of flexible vinyl tubing used to direct the cold air for circulation, or to hot spots. Tubing connectors and adhesive backed clips to hold the tubing in place are provided.

The Cabinet Cooler mounts to the enclosure through a drilled hole or electrical knockout. Side Mount Kits are available. NEMA 4 and 4X (IP66) Hazardous Location Cabinet Coolers may be mounted on the top of the panel or on the side of the panel if a Side Mount Kit is used (Model 4906 - Small Side Mount Kit; Model 4907 - Large Side Mount Kit).

Cabinet Cooler Systems with thermostat control include a solenoid valve and thermostat that limit the flow of compressed air to only when cooling is needed. Solenoid valves are rated 120V, 60Hz; 110V, 50Hz; 240 VAC or 24VDC. It is UL Listed and CSA Certified.

HazLoc Cabinet Cooler Systems with thermostat control include a Hazloc Solenoid NEMA 4X/7/9, 1/4 NPT Solenoid Valve that limits the flow of compressed air to only when cooling is needed. The solenoid valve is rated 120V/60HZ, 240V/60HZ or 24VDC. It is UL Classified.

The thermostat is factory set at 95°F (35°C). It will normally hold ±2°F (1°C) inside the cabinet. It is rated 24VAC-240VAC, 50/60Hz, 24VDC and is UL Recognized and CSA Certified.
