 Vortex Tubes are
an effective, low cost solution to a wide variety
of industrial spot and process cooling needs. With
no moving parts, Vortex Tubes spin compressed air
to separate the air into cold and hot air streams.
While French physicist Georges Ranque is credited
with inventing the vortex tube in 1930, ITW Vortec
was the first company to develop and apply this
phenomenon into practical and effective cooling
solutions for industrial use.
Vortex Tubes Applications:
Vortex Tubes have a very wide range of application
for industrial spot cooling on machines, assembly
lines and processes.

How
Vortex Tubes Work
Fluid (air) that rotates around an axis (like a
tornado) is called a vortex. Vortex Tubes create
cold air and hot air by forcing compressed air through
a generation chamber which spins the air centrifugally
along the inner walls of the Tube at a high rate
of speed (1,000,000 RPM) toward the control valve.
A percentage of the hot, high-speed air is permitted
to exit at the control valve. The remainder of the
(now slower) air stream is forced to counterflow
up through the center of the high-speed air stream,
giving up heat, through the center of the generation
chamber finally exiting through the opposite end
as extremely cold air. Vortex Tubes generate temperatures
down to 100°F below inlet air temperature. A control
valve located in the hot exhaust end can be used
to adjust the temperature drop and rise for all
Vortex Tubes.
