Achieve the Perfect Temperature with EXAIR’s Adjustable Spot Cooler

EXAIR’s Adjustable Spot Cooler is an ideal fit for those who need the ability to adjust the temperature of their spot cooling solution. This user-friendly tool is available right out of the box with the necessary accessories to allow you to quickly install and implement the solution. It can be great for dry-machining processes or applications where you’re looking to replace a standard coolant-based method of cooling.

If that sounds like something you’re looking for, then the Adjustable Spot Cooler could be an excellent product for optimizing your processes. EXAIR’s Adjustable Spot Cooler incorporates Vortex Tube technology to produce temperatures ranging from -30°F – +70°F. A Vortex Tube works by imparting a rapid spinning motion to the supplied compressed air. This airflow makes its way to the end of the tube where it is forced to abruptly change direction. It is during this change of direction that energy is given off in the form of heat. The hot air then exits the tube from the hot end, while cold air exits the other end of the tube. As the valve is opened to allow more air to exhaust from the hot end, the temperature at the cold end will decrease. At a sound level of just 73 dBA when operated at 100 psig and a stock generator installed, this compact cooler will keep your operation clean and dry without causing unnecessarily high noise levels.

When looking at a Vortex Tube based solution, the variety of options can sometimes be daunting. This is where the Adjustable Spot Cooler shines. Through a simple turn of the control knob, you can easily adjust the temperature and cold fraction of the unit. Additionally, the kits come with (2) extra generators (15-H and 30-H) that can be swapped out for the stock generator for more/less cooling power and air consumption. The 15-H generator will deliver up to 1,000 Btu/hr of cooling capacity and the 30-H will provide up to 2,000 Btu/hr of cooling capacity. We have (2) different kits available, the Model 3825 Single Point and the Model 3925 Dual Point Kit. The 3825 is recommended for use in applications where you’re cooling a small surface such as solder joints, hot melts, or drilled plastics. The 3925 system is better served when heat is generated over a larger surface area, such as saw blade cooling. The kits use a flexible Loc-Line hose to allow you to precisely position the cold airflow onto your target. The Adjustable Spot Cooler provides easy mounting with a swivel magnetic base, allowing you to position the cold air flow directly at the most critical point where heat is being generated.

If you’re tired of cleaning up your coolant or have an application that requires dry machining, get one of the Adjustable Spot Cooler systems on order today. They’re in stock ready to ship the same day with an order received by 2:00 ET!

The Adjustable Spot Cooler utilizes the Vortex Tube technology that converts compressed air into a cold air stream. To learn more about EXAIR vortex tubes, click here.

  • It can produce temperatures form -30 °F to +70 °F (-34 °C tp +21 °C)
  • Parts included for flow rates of 15, 25 and 30 SCFM (425, 708, 850 SLPM.) The unit comes from the factory set at 25 SCFM (708 SLPM)
  • It can produce refrigeration up to 2,000 BTU/hr (504 Kcal/hr.)

A swivel magnetic base allows for easy mounting and portability, you can move it from machine to machine as needed. The flexible cold air outlet tubing holds its position and is easy to aim. Most importantly, there are no moving parts or CFC’s, ensuring maintenance free operation.

How the Adjustable Spot Cooler Works

The Adjustable Spot Cooler incorporates a vortex tube to convert a 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 air stream (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.


The Adjustable Spot Cooler can produce a wide range of air flows and temperatures as determined by the temperature control valve knob setting and the generator installed. The generator controls the total SCFM (SLPM) of compressed air consumption, and is easy to change. From the factory, the 25 SCFM (708 SLPM) generator is installed, producing up to 1,700 BTU/hr (429 Kcal/hr) of cooling. For less cooling, the 15 SCFM (425 SLPM) generator can be installed, providing up to 1,000 BTU/hr (252 Kcal/hr) of cooling. And for more cooling, the 30 SCFM (850 SLPM) generator can be installed, providing up to 2,000 BTU/hr (504 Kcal/hr) of cooling.
