A Vortex Tube is a device which utilizes compressed air to produce cold air by creating a vortex effect inside the tube. The vortex effect basically expells the hot air and directs the cool air to seperate outlet. The Nexflow Frigid Vortex Tube is available in sizes between 700 - 2800btu. Our Vortex Tubes are supplied with a hot end muffler.
A Vortex Tube has no moving parts and is virtually maintenance free. The main requirement of a Vortex Tube is that the compressed air supply is clean and dry. A Vortex tube can produce cold air down to -35°C and hot air up to +127°C. Compressed air is injected tangentially into the tube at sonic speed and creates a cyclone (Vortex) spinning at about one million revolutions per minute. Part of the air is forced to spin inward to the centre hole and travels up the long tube where a valve turns this spinning column (Vortex) of air inside itself. The inside column of air gives up its heat to the outside column. The cold air is then directed out the cold end of the Vortex Tube. The temperature and air flow are totally controllable by adjusting the valve at the hot end of the tube.
Nexflow Frigid Vortex Tubes are available in the following sizes:
