High summer temperatures bring concerns for any manufacturing facility, including those related to windpower. After ensuring employee safety, it is also important to safeguard sensitive electronics from the heat.
Exair cabinet coolers cool and purge electronic control panels. They 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.
NEMA 12, 4, and 4X Cabinet Coolers that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels.
- Cabinet cooler systems with Electronic Temperature Control (ETC) allow for easy adjustment of thermostat, providing precise temperature control.
- Cabinet cooler systems with thermostat control save air by activating the cooler only when internal conditions approach critical levels.
- Continuous operation cabinet cooler systems are recommended when constant cooling and constant positive purge are desirable.
The vortex tubes incorporated in Exair cabinet coolers are constructed of stainless steel. The wear, corrosion and oxidation resistance of stainless steel assures long life and maintenance-free operation. All cabinet coolers are UL and ULC-listed and CE-compliant.
How Exair cabinet coolers work
Compressed air enters the vortex tube-powered cabinet cooler and is converted into two streams, one hot and one cold. 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.
