Instantly Control Air Temperature

Instant cold or hot air – from -40°f to 230°f – from ordinary compressed air.

It’s your answer for instant cold air, where and when you need it, using nothing but compressed air as a power source. There’s no maintenance, no mess, no explosion hazard, no electricity, no moving parts – just clean, cold air for industrial or laboratory spot cooling.

Industrial Solutions For Vortex Tubes

Diagram of a Vortex Tube cooling a metal tap operation.

Metal Fabricating – Tapping

Tapping brass clips is completed without messy liquid coolants using air from a Vortex Tube to cool the tap. The brass does not have a chance to gum up, the cut is cleaner, and secondary operations are eliminated.

Plastic – Slitting

Cutting wheels on this slitter can work at top speed and stay sharper longer – when cold air from Vortex Tubes eliminates the friction heat build-up. The trim edge is also cleaner.

Transportation Spot-Welding

Cooling this spot-welding operation with a Vortex Tube virtually eliminates secondary smoothing operations, and greatly improves the appearance of the product.

Metalworking – Single Point Threading

Heat build-up in this single point threading operation can shorten tool life and produce a rough thread. Clean, dry, sub-zero cooling allows increased speed, while eliminating tool microcracking and premature failure.

Frequently Asked Questions

How do Vortex Tubes Work?

The vortex tube sets up two streams of air at different speeds. As the two streams pass each other there is an air to air heat exchange with the slower speed stream of air giving up its heat to the fast moving stream. So you have one colder stream and one hotter stream of air than the ambient air you started with. You are welcome to call 800 307 7475 if you have particular questions on your application.

Where can I use the Vortex Tube?

Anywhere you need very cold or very hot air. Use it to cool hot parts, molds, electronics, machining operations, personnel, all without bulky freon units. Use it to heat shrink wraps, glues, or for drying parts.

Is there anything to wear out or replace?

No, They may need cleaning from contaminated air, but because there are no moving parts, it does not wear out.
