Adjustable Spot Cooler

Cold air to -30ºF (-34ºC) from your compressed air supply for spot cooling!

What is The Adjustable Spot Cooler?

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 -30ºF (-34ºC) to room temperature.

The Adjustable Spot Cooler incorporate a Vortex Tube that converts an ordinary supply of compressed air into cold air.

  • It can produce temperatures from -30º to +70ºF (-34º to +21ºC)
  • Parts included for flow 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.

Why The Adjustable Spot Cooler?

The Adjustable Spot Cooler is quiet (lee than 75 dBA), easily set with a thermometer and holds the temperature setting. It's ideal for applications where mist or liquid cooling can not be used due to part contamination or cost. Tolerances, product finish and production rates can improve dramatically.

The Adjustable Spot Cooler is available with either a single point or dual point hose kit. The singe point system (Model 3825) is recommended for cooling a small surface like solder joints, hot melts or drilled plastics. The dual point system (Model 3925) is recommended when heat is generated over a larger surface area.

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. 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.
