NEMA Type 3R (IP 14) Cabinet Panel Coolers for outdoor use. Stainless steel to hold up to rain, snow, humidity and general outdoor use.
The NEMA 3R Cabinet Panel Coolers provides a low cost method of both purging and cooling electrical and electronic control panels by using a stainless steel vortex tube to create cold air from ordinary compressed air
Unlike many of our competitors all of our Frigid-X NEMA 3R Cabinet Panel Coolers are stainless steel, not just the vortex tube, for longer life and flexible use. Frigid-X NEMA 3R Cabinet Panel Coolers are compact and can be installed in minutes through a standard electrical knockout. There are virtually no moving parts.

How NEMA 3R Cabinet Panel Coolerss Work
Compressed air enters at point (A) into the vortex tube component of the panel cooler. The vortex tube splits the compressed air into a hot (B) and cold (C) stream of air. The hot air from the vortex tube is vented to the atmosphere at point (D) after being muffled to reduce noise. Hot air displaced from inside the control panel cooler or cabinet enclosure cooler is exhausted through point (E). Cold air enters into the panel (F) via the cold distribution hose (G). Holes (H) are punched into the hose kit to deliver the cold air inside the panel cooler where required. A muffler (I) further reduces the noise level of the exhausting air.
How to Calculate Heat Load for Your Enclosure Panel
To determine the correct Enclosure Panel cooler model for your application, it is first necessary to determine the total heat load to which the panel is subjected.

High Temperature Warning Sticker
Frigid-X Electronic Control Panel Coolers can provide a cooler master cabinet which may have smaller enclosures inside.
Cabinet Panel Coolers Manufacturers:
There are many Electronic Control Panel Coolers manufactures which are normally air conditioners, heat exchangers, fans or other vortex cooler systems.
How to Cool Electrical Enclosures:
Electrical enclosures or cabinets can be cooled several ways. They may be cooled by fans, water-cooled systems, heat pipe heat exchangers and air conditioners. Each system has potential limitations in cooling, or maintenance costs or can be affected by the ambient air. The Frigid-X Electronic Control Panel Coolers however are virtually maintenance free.
Electronic Temperature Control:
Electronic Temperature Control is available for the Frigid-X Electronic Control Panel Coolers.
The Adjustable Thermostat provided with our Frigid-X Electronic Control Panel Coolers for on-off control is preset but is also an Adjustable Thermostat to reset the temperatures if desired.

Frigid-X NEMA 3R Cabinet Panel Coolers Sizing Specifications:
Contact Nex Flow for assistance in sizing cabinet enclosure cooler - Frigid-X series.
** In 316 environments normally customers will have special filtration systems for such environments already.
*Cooling effect based on 95ºF temperature inside cabinet, 100 PSIG (6.9 BAR) compressor inlet pressure, and 70ºF (21ºC) inlet temperature. BTU/hr. figures rounded to nearest 100 BTU/hr (1 WATT).
All Continuous Operation models include the cooling unit, filter with auto drain and cold air distribution kit.
All On-Off control units include the cooling unit, filter with auto drain, cold air distribution kit, solenoid valve and thermostat.
Frigid-X NEMA 3R Cabinet Panel Coolers Selection
Frigid-X Electronic Control Panel Coolers come with a 5 micron filter with an automatic drain (except for the 316L stainless steel units) for the compressed air supply to insure clean, dry air and an air distribution kit to circulate the cold air inside the enclosure for even cooling.
Frigid-X Electronic Control Panel Coolers are available with or without thermostat control.
When constant cooling and a constant positive purge is required we recommend the continuous operating version without the thermostat and solenoid valve. The cooling effect can be controlled by adding a regulator in line to reduce pressure for reduced cooling when it is not required and to conserve energy.
Systems utilizing a thermostat and solenoid valve saves air by activating the air conditioner only when the internal temperature reaches a critical level. The adjustable thermostat is factory set at 95°F but can be readjusted on site.
Thermostat and solenoid valve systems are recommended where the heat load can fluctuate (such as for frequency drives) and where a continual purge is not required. The thermostat and solenoid "package" can also be added at a later date to a continuous system. An Electronic Thermostat System is also available replacing the thermostat and solenoid valve with a control box to “set” the temperature (ELC System).
If mounting cannot be on the top of the control panel an optional side mount is available (except or the 316L stainless units). Enclosure Cooling System must be mounted vertical either at the top or at the side using the side mount.

Frigid-X Electronic Control Panel Coolers are available with thermostat control (On/Off units) or continuous operation. Continuous systems are best when constant cooling and/or a positive purge of the panel is required. On/Off control saves air by activating the unit when the internal temperature a critical level. the adjustable thermostat is factory set at 95ºF (35ºC). They are best used in applications where heat may fluctuate as in variable speed drives and where continuous purge is not required. All of our Frigid-X Electronic Control Panel Coolers are stainless steel for long life and flexible environments.
If a constant positive pressure is required with On/Off control (non-hazardour purge units) a special solenoid valve can be supplied to allow a small amount of air flow into the control panel when in the closed position. High temperature units for ambient temperatures in excess of 150ºF (67ºC) to 200ºF (93ºC) and higher are available.
