Cabinet Cooler® – NEMA 4 (IP66)
Our cabinet coolers for dust-tight, oil-tight, and splash-proof enclosures put an end to downtime of electronic controls caused by heat, dirt, and moisture — both indoors and outdoors. Check valves provide a liquid-tight seal when the units are not in use.
- SSK units supply clean, cold air to your electronic enclosures
- Low-pressure relief valves maintain NEMA 4 enclosure integrity
- Manufactured from aluminum and Type 303 stainless steel for long service life
Try it yourself – our cabinet coolers are available as test units!
EXAIR compressed air solutions can be requested at any time as a TEST UNIT. If you are satisfied with the performance and decide to purchase the product, the rental fee will be credited toward the purchase price.
Why EXAIR Cabinet Cooler Systems?
The Vortex tube in the EXAIR Cabinet Coolers is constructed of stainless steel. The wear, corrosion and oxidation resistance of stainless steel assures long life and maintenance free operation.
Cabinet Coolers maintain NEMA 4 are dust-tight, splash resistant and for indoor/outdoor service. NEMA 4 Cabinet Coolers incorporate a low pressure relief valve for both the vortex tube and the Cabinet Cooler exhaust. The valve closes and seals when the Cabinet Cooler ist not operating to maintain the NEMA 4 integrity of the NEMA 4 enclosure.

To determine the correct model for your application, it is necessary to determine your requirement.
EXAIR Cabinet Coolers are available with or without thermostat control. The continuous coolers (Model series 4200 and 4700) are recommended when constant cooling and a constant positive purge are desirable. A thermostatically system saves air by activating the cooler only when the internal temperature is critical.
All Exair Cabinet Cooler Systems contain a 5 micron Automatic Drain Filter for the compressed air supply and a Cold Air Distribution Kit to circulate the cold air throughout the enclosure.
How The 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 information on vortex tube operation, see Vortex Tubes section. 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.

Heat can stop your machinesIt happens when you least expect it. High temperatures can cook the electronics that control your machines, resulting in erroneous readings, trip-outs or fried circuit boards. Cooling the electrical cabinet can eliminate these problems, but how will you do it? |
 Es besteht eine hohe Schockgefahr, wenn die Schalttafeltür geöffnet wird und ein Ventilator heiße, schmutzige Fabrikluft auf die Elektronik bläst. |
Heat Exchangers and Heat PipesThese have serious limitations when it comes to summer time heat. In many cases, the temperature of the hot plant on a summer day is close to that inside the enclosure. There is not enough difference in temperature for a decent heat exchange. |

Refrigerant Panel Air ConditionersThese coolers are expensive, take almost a day to install, and are prone to failure when dust and dirt clogs the filter. Vibration from machinery contributes to component failures and loss of freon. Life expectancy for most compressors is rated at 2.5 years of continuous operation. Average replacement cost for a bad compressor is $750 plus installation. Often, a floor drain is not readily available for the condensation tube. |

EXAIR Cabinet CoolerOur compressed air operated Cabinet Coolers are the low cost solution. NEMA 12, 4 and 4X models are available that are very compact and mount in just minutes through an ordinary electrical knockout. Thermostat control limits compressed air use by operating the Cabinet Cooler only when the temperature inside the enclosure reaches critical levels. Heat exchangers, heat pipes and refrigerant coolers all have filters that can clog. Left unattended, mechanical failure of the cooler is likely. And, the expensive equipment in the electrical enclosure can malfunction, overheat and shut down the entire machine or process. EXAIR Cabinet Coolers have no moving parts to wear out and do not require constant monitoring. All models are UL Listed and available in a large number of styles and cooling capacities. |

Electronic Temperature ControlThe digital Electronic Temperature Control (ETC) provides precise temperature control for your electrical enclosure. It can accureately maintain a constant temperature that is slightly under the maximum rating of the electornics, 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 (°C or °F) that is constantly being monitored by a quick response thermocouple. The control activates the solenoid valce (included) when the temperature setting is exceeded. The polycarbonate plastic enclosure of the ETC is suitable for NEMA 12, 4 and 4X environments. |
