Cooling with the Cold Gun Aircoolant System and Vortex Tubes

Vortex Tubes are a low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. EXAIR has used this vortex tube in the Cold Gun Aircoolant System™ to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used. EXAIR's Cold Gun is non-adjustable to prevent freeze-up during use.

Using an ordinary supply of compressed air as a power source, vortex tubes create two streams of air, one hot and one cold, with no moving parts. Temperatures, flows and cooling power are adjustable over a wide range using the control valve on the hot end exhaust.

EXAIR Vortex Tubes are available in three sizes. Each size can produce a number of flow rates, as determined by a small internal part called a generator. If Btu/hr. (Kcal/hr.) requirements, or flow and temperature requirements are known, simply select the appropriate vortex tube according to the specification information. Keep in mind that the vortex generators are interchangeable. If, for example, a Model 3215 Vortex Tube does not provide sufficient cooling, you need only change generators within the vortex tube to upgrade the flow rate from 15 to 25, 30 or 40 SCFM (425 to 708, 850 or 1,133 SLPM).
