Streamtek Compressed Air Products - Vortex Tubes


Vortex Tubes are 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.
  • Cooling electronic controls
  • Cooling machining operations
  • Setting hot melts
  • Cooling soldered parts
  • Cooling gas samples
  • Electronic component cooling
  • Cooling heat seals.
  • Cooling environmental chambers
  • Maintenance free (No moving parts)
  • Cools without costly electricity or refrigerants
  • Reliable, compact and lightweight
  • Low cost application
  • Durable - Stainless Steel
  • Adjustable temperature
  • Instant cold air

Streamtek 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 STREAMTEK™ Vortex Tube will provide years of reliable, maintenance free-operation.

Inlet Air Temperature - The STREAMTEK™ Vortex Tube will provide a temperature drop from the temperature of the compressed air supply.

Back Pressure - A low back pressure, up to 2 PSIG (.1 BAR), will not affect the performance of the STREAMTEK™ Vortex Tube. Anything over this will have a performance degration of ~ 5ºF (2.8ºC).

Filtration - Filtration to maintain clean air is necessary at a rate of 25 microns or less. STREAMTEK™ filters contain a 5 micron element and are properly sized for airflow.

Noise/Muffling - Both Small and Medium Vortex Tubes can be quite noisey if unducted. STREAMTEK™ offers mufflters for both cold and hot air discharge. If the cold air is ducted, muffling is not usually required.

7700 series Vortex Tubes are used in applications which require extreme cold termperatures such as circuit board testing, and lab sampling cooling. These Vortex Tubes provide the lowest cold air temperatures, but at a low cold airflow (when less than a 50% cold fraction is used). The 7700 series Vortex Tubes should be only used when temperatures below 0º (-18ºC).
