Compressed air is injected into the vortex tube at extremely high speeds and that creates a cyclone, or vortex, spinning a million revolutions per minute. Part of the air is forced to spin inward to the center and travels up a long tube where a valve turns the spinning column of air inside itself. The inside column of air gives up its heat to the outside column. The cold air is directed out the cold end of the Vortex Tube and the hot air is directed out the other end of the Vortex Tube. The air flow and temperature are totally controllable. And since there are no moving parts there is little need for maintenance. A Vortex Tube is useful in many applications from spot cooling to creating a "cooling chamber" in a haunted house.  If you have any questions about using a vortex tube please call to discuss your application.
