The Weizhi Vortex Tube uses compressed air to produce clod air for industial spot cooling.The Vortex Tube can convert compressed air into two air streams. One stream is hot air and the other stream is cold air. The cold air can be adjusted down to -40 degrees Centigrade，and the hot side can be adjusted up to a temperature of 120 degrees Centigrade.
  Weizhi Vortex Tubes have an adjustable valve at the "hot" end controls the volume of the air flow, and the temperature exiting at the cold end. By adjusting the valve, you control the "cold fraction" which is the percentage of total input compressed air the exits the cold end of the Vortex Tube.
  Weizhi Vortex Tubes are constructed of stainless steel and provide years of reliable,maintence free opration.
