nemacc.jpg (120782 bytes)What are EXAIR Cabinet Coolers?
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.

Why EXAIR Cabinet Coolers?
The vortex tube incorporated in the EXAIR Cabinet Cooler Systems is constructed of stainless steel. The wear, corrosion and oxidation resistance of stainless steel assures long life and maintenance-free operation of EXAlR Cabinet Cooler Systems.

How the EXAIR Cabinet Cooler Works

Compressed air enters the vortex tube powered Cabinet Cooler and is converted into two streams, one hot and one cold. (For more details on the theory behind vortex tubes, click here.)  Hot air from the vortex tube is muffled and exhausted through the vortex tube exhaust.  The cold air is discharged into the control cabinet through the cold air distribution kit.  The displaced hot air in the cabinet rises and exhausts to atmosphere through the cabinet air exhaust at a slight positive pressure.  Thus, the control cabinet is both cooled and purged with cool, clean air.  Outside air is never allowed to enter the control panel.Filtration:
EXAlR Cabinet Cooler Systems include a 5 micron automatic drain water and dirt filter. This filter is critical for protection of electronics from water 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.

Cold Air Distribution Kit:
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.
Systems for continuous operation include a Cabinet Cooler, distribution kit and filter.
Systems with thermostat control include a Cabinet Cooler, thermostat, solenoid valve, cold air distribution kit and filter.
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.)

Solenoid Valve and Thermostat:
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. The solenoid valve is rated 120V, 60 Hz or 110V, 50 Hz. It is UL Listed, CSA Certified.

The thermostat is factory set at 95°F (35°C). It will normally hold ±2°F (1°C) inside the cabinet. It is rated 120V, 50/60 Hz and is UL Recognized, CSA Certified.

Inlet Air Temperature:
Cabinet Cooler Systems provide a 50°F (28°C) temperature drop from supply air temperature when the inlet pressure is 100 PSlG (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.
The Cabinet Cooler mounts to the enclosure through a drilled hole or electrical knockout. The NEMA 12 Cabinet Coolers may be mounted on the top or side of the panel. NEMA 4 and 4X Cabinet Coolers must be mounted on the top of the panel.
