The Adjustable Spot Cooler incorporates a vortex tube to convert an ordinary supply of compressed air into two low pressure streams, one hot and one cold. With the turn of a knob, the temperature control valve allows some hot air to flow through a muffling sleeve and out the hot air exhaust. The opposite end provides a cold airstream that is muffled and discharged through the flexible hose, which directs it to the point of use. The swivel magnetic base provides easy mounting and portability. EXAIR's compressed air powered Adjustable Spot Coolers are 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. 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.
