COLD AIR INSTANTLY USING ONLY COMPRESSED AIR STAINLESS STEEL CONSTUCTION
VORTEX TUBES-WHAT ARE THEY?
A Vortex Tube is a device with no moving parts that will conver ordinary stream of compressed air into two streams-one hot and one cold. A Vortex Tube can produce cold air down to -50degrees F.and hot air up to 260degrees F.
HOW DO VORTEX TUBES WORK?
Compressed air is injected circumferentially into the tube at sonic speed and creates a cyclone(Vortex) spinning at a million revolutions per minute. Part of the air is forced to spin inward to the center hole and travels up the long tube where a value turns the spinning column(Vortex) 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 exhausted out of the other end of the Vortex Tube. The temperature and airflow is totally controllable by adjusting the knob on the hot end of the Vortex Tube .
