EXAIR's Adjustable Spot Cooler System (one cold outlet) includes everything needed for a single point cooling station that offers a low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. With the turn of a knob, you can select a precise temperature setting from -30°F (-34°C) to room temperature. A swivel Magnetic Base provides easy mounting and portability. A Single Point Hose kit (with cone and fan nozzle) directs the cold air. 15 & 30 SCFM (425 & 850 SLPM) generators are included and a 25 SCFM (708 SLPM) generator is installed. An Automatic Drain Filter Separator is included to insure a supply of clean air. No moving parts or CFC's assures maintenance free operation.

*25 SCFM (708 SLPM) generator is factory installed. Air consumption is based on generator installed.

Adjusting the Spot Cooler

The Adjustable Spot Cooler System can produce a full range of airflows and temperatures as determined by the knob setting and a small internal part called a generator. The generators control the SCFM (SLPM) of air consumption and are easily interchangeable. The Adjustable Spot Cooler has a 25 SCFM (708 SLPM) generator installed that produces up to 1,700 Btu/hr. (498 Watts). If less cooling is desired, the 15 SCFM (425 SLPM) generator, which delivers 1,000 Btu/hr. (293 Watts), can be installed. If more cooling is needed, the 30 SCFM (850 SLPM) generator can be installed for up to 2,000 Btu/hr. (586 Watts).

How It 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. 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.

Controlling the Cold Air

The Adjustable Spot Cooler gives instant cold air when filtered compressed air is supplied to it. Cycling on and off is a good way to save air. For on and off control, use a Model 9012 Manual Shutoff Valve. To turn the Adjustable Spot Cooler on with the machine, the Model 9020 Solenoid Valve may be used and wired through the machine control switch. The EFC electronic flow control can also be used.
