function properly, the main will trip
and cause the whole system to go
down.
When temperatures in the
panel skyrocketed, multifunction electronic controls
could misread, drift, or trip
breakers below rated loads,
ultimately leading to production
downtime to make repairs. The
small size of the cabinet and lack of
access to the panel, in turn, made the
frequent repairs difficult.

SOLUTION
Cohran learned about Vortec's Vortex Enclosure
Coolers through online research. These coolers are
designed to keep electronic panels clean and
protected by maintaining pressurization in the

cabinet. They are thermostatically controlled to maintain enclosure temperatures within an ideal range.
The Vortec units are designed around the vortex-tube principle, providing an economical alternative with no moving parts. Vortex tubes convert
compressed air to a low-pressure cold-air source to
keep electronic enclosures and panel components
protected so they can operate precisely. A compressed-air stream enters the vortex tube where it
spins rapidly, splitting into hot and cold air streams.
Cooling performance is easily adjusted by changing
the inlet air pressure or by changing the generator in
the tube itself.
Cohran installed two 787SS Vortex coolers at the
client's site. He also installed a water separator to
keep moisture out of the cabinet housing the three
VFDs. Since then, the electrical panel has maintained
a steady, cool, 56 F temperature that's low enough to
keep the drives from overheating.

Chuck Cohran installed two 787SS Vortex Enclosure Coolers at his client's site, and the panel temperature has stayed at
a steady, cool, 56 F ever since.

hard-hitting curtain of air for
blowoff, cleaning, drying and cooling.
SUPER AIR KNIFE Quiet,

EXAIR's engineered Super Air Knife dramatically reduces compressed air use
and noise when compared to other blowoffs. It offers a more efﬁcient way to
clean, dry or cool parts, webs or conveyors. A uniform sheet of laminar airﬂow
across the Super Air Knife's entire length delivers hard hitting force upon your
target. With an air ampliﬁcation ratio (entrained air to compressed air) of 40:1,
the Super Air Knife also delivers a maximum volume of air. The Super Air
Knife meets OSHA standards for dead-end pressure and noise exposure to
keep your personnel safe and comfortable.

Available in Aluminum,
Type 303 and 316 Stainless Steel
and PVDF; ships same day for
orders placed by 3:00pm Eastern.
Static Elimination
models also available.
Stocked in 3" to 108" lengths.
Surprisingly Quiet! Only 69 dBA!
Reduced Air Consumption.
