Vortex Tubes and Spot Cooling

pdf Adjustable Spot Cooler

Cold air to -30°F (-34°C) from your compressed air supply for spot cooling!

A low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. With the turn of a knob, you can select the temperature best suited to your application.The Adjustable Spot Cooler provides a precise temperature setting from -30°F (-34°C) to room temperature.
The Adjustable Spot Cooler incorporates a vortex tube that converts an ordinary supply of compressed air into cold air.
• It can produce temperatures from -30° to +70°F (-34° to +21°C)
• Parts included for fl ow rates of 15, 25, and 30 SCFM (425, 708 and 850 SLPM). 25 SCFM (708 SLPM) generator is factory installed.
• It can produce refrigeration up to 2,000 Btu/hr. (504 Kcal/hr.)
A swivel magnetic base provides easy mounting and portability. Flexible tubing that holds its position directs the cold air. No moving parts or CFC’s assures maintenance free operation.

How The Adjustable Spot Cooler Works

The Adjustable Spot Cooler incorporates a vortex tube to convert an ordinary supply of compressed air (1) into two low pressure streams, one hot and one cold. (For complete information on vortex tube operation, see page 175.) With the turn of a knob, the temperature control valve (2) allows some hot air to flow through a muffling sleeve and out the hot air exhaust (3). The opposite end provides a cold airstream (4) that is muffled and discharged through the flexible hose, which directs it to the point of use. The swivel magnetic base (5) provides easy mounting and portability.
