Other Considerations
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.
| Cabinet Cooler Systems: |
 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. |
|
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. |
 Cold Air Distribution Kit includes tubing, adhesive clips and fittings. |
Humidity:
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.)
Inlet Air Temperature:
Cabinet Cooler Systems provide a 50°F (28°C) temperature drop from supply air temperature when the inlet pressure is 80 PSIG (5.5 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.
Mounting:
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. Side Mount Kits are available. (Model 4909 - Small; Model 4910 - Large.) NEMA 4 and 4X 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; Model 4907 - Large).

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 24V-240V, 50/60 Hz and is UL Recognized, CSA Certified.  |

Electronic Temperature Control: EXAIR’s new 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. The polycarbonate plastic enclosure of the ETC is suitable for NEMA 12, 4 and 4X environments. (Cabinet Cooler not included.) |
