Vortex Tubes from Knight Pneumatics are an effective, low cost solution to a wide variety of industrial spot and process cooling needs. With no moving parts, a vortex tube spins compressed air to separate the air into cold and hot air streams.

Functions of vortex tubes:

Fluid air that rotates around an axis is called a vortex. A Vortex Tube creates 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.

Applications of vortex tubes include:

  • Set solders and adhesives
  • Cool heat seal operations
  • Temperature cycle parts
  • Dry ink on labels and bottles
  • Cool Machining Operations
  • Thermal test sensors and choke units
  • Dehumidify gas operations
  • Cool cutter blades
