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. NEMA 4, 4X and 12 Cabinet Coolers
that match the NEMA rating of the enclosure are
available in many cooling capacities for large and
small control panels.
A
Model 4830 NEMA 4 Cabinet Cooler cools a panel
with 20°F air while keeping the inside dry.
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.
All Cabinet Coolers are UL Listed.

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.
