The Secret To Keeping Electronics Cool!
NEMA 12
Cabinet Coolers

The NEMA 12 Cabinet
Coolers for large heat loads
up to 5,600 Btu/hr. are
ideal for PLCs, line
control cabinets, CCTV
cameras, modular control
centers, etc.

A bad choice could cost you thousands!
Look Familiar?
When hot weather causes the electronics
inside a control cabinet to fail, there is a
panic to get the machinery up and running
again. The operator might choose to simply
open the panel door and aim a fan at the
circuit boards. In reality, the fan ends up
blowing a lot of hot, humid, dirty air at
the electronics and the cooling effect is
minimal. If the machinery starts functioning
again, the likelihood of repeated failure is
great since the environment is still hot
(and threatens permanent damage to
the circuit boards). Worse yet, that open
panel door is an OSHA violation that
presents a shock hazard to personnel.

from entering through small
holes or conduits. For use in
non-hazardous locations.

want to risk another heat failure. Fans weren't an option since they would
just blow around a lot of hot air. Freon-type air conditioners like those on
some of our other machines were a constant maintenance project of their
own. We purchased EXAIR's Model 4330 NEMA 12 Cabinet Cooler

System since it was easy to install and requires no maintenance."
