What is a Vortex Tube?

What is a General Imsubs Vortex Tube? The General Imsubs Vortex Tube is an effective, low cost solution to a wide variety of industrial spot cooling and process cooling needs. Compressed air is injected into the vortex tube, flows at a rate of up to 1,000,000 RPM towards the 'hot' end of the tube. Once this hot air reaches the end, a small amount is exhausted through a control valve. The rest of the air is forced backwards towards the other end and exits as 'cold' air. The Vortex Tube can decrease temperatures by ~115°F (46°C) and raise temperatures up by ~200°F (93°C) from the initial inlet air temperature. Vortex tubes are available in two sizes, Small and Medium depending upon compressed air consumption.

Which Vortex Tube will best suite my needs?
Our Vortex Tubes are available in 2 sizes (Small and Medium). Each Vortex Tube is constructed of stainless steel. The wear resistance of stainless steel, as well as its resistance to corrosion and oxidation, assures that Vortex Tube will provide years of reliable, maintenance free-operation.

Advantage of Vortex tube
	Safety, as no electricity at the point of application. No RF interference. Low cost of ownership Lower noise. SS 304 construction. Special material constructions available on specific order. Available in two sizes Enhances reliability and durability of equipment
	Applications or Vortex Tube
	Heat sealing machines Sewing machine needle cooling Tools and plastic grinding and machining Spot cooling Laboratory instrument / chambers cooling. Ultrasonic welding horn cooling Dry machining Camera cooling in spray drier, induction furnaces and such applications.

HOW IT WORKS: Vortex Tubes

• • (A) Compressed air, normally 80 to 100 PSIG (5.5 - 6.9 BAR) enters the Vortex Tube through a standard BSP inlet and tangentially through a generator into the vortex spin chamber.
     
  • (B) This air stream spinning at up to 1,000,000 RPM travels in one direction along the small (hot end) tube and then is forced back through the center of this outer vortex.
     
  • (C) The brass control valve on the hot end allows for quick n' easy adjustment of the "cold fraction".
  
  
  • (D) As the center column travels towards the opposite end, it gives off kinetic energy in the form of heat to the outside stream of air and exits the vortex tube as cold air.

Cable wipers provides effective solution for wiping of water on electric cable and tube extrusion plants. Available in various sizes. Air knives are air amplifying linear blow off devices used for cooling or cleaning of flat surfaces.
