Vortex Tube: The Perfect Cooling Solution

The use of Vortex Tube is in great vogue today- be it for industrial purpose, commercial use or even residential applications. A gift of modern technology, the vortex tube products are today available that are suited to carry out specific applications. These include tubes in three sizes- small, medium and large vortex tubes that have a wide range of cooling capacities. There is the adjustable spot cooler that is used to adjust thermostats, set hot melts, cool machined or molded plastics and more. Then there are cabinet coolers that cool and cleanse electronic enclosures. They also eliminate malfunctions caused by overheating or dirt infiltration.

On the other hand, Cold Gun Air coolant System replaces messy mist systems, cools dry machining operations with clean, cold air. Again component cooler offers a clean, safe way to test electronic components using -40°F (-40°C) air. It ends thermal shock and the environmental problems associated with expendable aerosols.

Nowadays, there are also mini cooler variety of vortex tube that prevents burning, melting and heat related breakage on small parts with 20°F (-7°C) air. It is ideal for small tools, blades, sewing needles, and lenses.

It is found that a Vortex Tube can convert an ordinary supply of compressed air into cold air at -50°F (-46°C) on one end, up to 260°F (127°C) on the other. But they are commonly used to cool electronic controls, machining operations, gas samples, and environmental chambers etc.
