The Secret To Keeping Electronics Cool!
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.
* Measures 8" (203mm) high
* Mounts top, side or bottom
* Enclosure remains dust-tight
NEMA 4 and 4X
NEMA 4 and 4X Cabinet Coolers for
large heat loads up to 5,600 Btu/hr. They
are ideal for PLCs and modular controls.
* Enclosure remains dust-tight, oil-tight
and splash resistant
* Suitable for wet locations where coolant
spray or hose down can occur
Type 316 Stainless Steel
Type 316 Stainless Steel Cabinet Coolers
for NEMA 4X applications are available
for heat loads up to 5,600 Btu/hr.
* Resists harsh environments not suitable
for Type 303/304
* Ideal for food and chemical processing,
pharmaceutical, foundries, heat treating
and other corrosive environments
NEMA 4 and 4X Hazardous
Location Cabinet Coolers for use
with classified enclosure purge
and pressurization systems are
available for all Class I Div 1
environments up to 5,600 Btu/hr.
* Maintain NEMA 4/4X integrity
* Meet UL classified requirements
* CE compliant
DON'T DO THIS!
It is an OSHA violation that presents
a shock hazard to personnel.
The fan blows hot, humid,
dirty air at the electronics.
Refrigerant panel air conditioners cause
condensation and moisture.
When condensation is present, electrical
components can began to erode, resulting
in severe damage.
A bad choice could cost you thousands!
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.
The Real Solution!
Stop electronic downtime with an EX AIR Cabinet Cooler® System! The complete
line of low cost Cabinet Cooler Systems are in stock and can ship now. They mount
in minutes through an ordinary electrical knockout and have no moving parts to
wear out. Thermostat control to minimize compressed air use is available for all
models. All Cabinet Coolers are UL Listed to US and Canadian safety standards.

The only compressed air powered
cooler that is CE compliant!
High Temperature Cabinet
Coolers for NEMA 12, 4 and
4X applications are available
for heat loads in many capacities
up to 5,600 Btu/hr.
* Suitable for ambients up to
* Ideal for mounting near ovens,
furnaces, and other hot locations
"It took us three days to get a replacement computer cabinet and we didn't
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
Jeff Hauck, Lasercraft Inc. Cincinnati OH System since it was easy to install and requires no maintenance."
BE AWARE OF CONDENSATION!
NHP Cabinet Coolers keep a
slight positive pressure on the
enclosure to keep dirt from
entering through small holes
or conduits. For use in nonhazardous locations.
* Uses only 1 SCFM in purge mode
* For heat loads up to 5,600 Btu/hr.
* NEMA 12, 4 and 4X
