EXAIR’s Adjustable Spot Cooler: A Versatile Tool for Your Cooling Needs!

 

If you’re looking at replacing messy coolant mist systems, look no further than the Adjustable Spot Cooler. 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 directions. 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 stock generator installed, this compact cooler will keep your operation cool, 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 versatility of 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 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 mount the cooler directly at the most critical point that heat is being generated.

EXAIR At BI-MU With Italian Distributor

Lee with Magugliani team
Myself, Lee Evans, with the Magugliani team.

I had the pleasure of attending the BI-MU exhibition with our Italian distributor, Magugliani SRL, from September 30th – October 4th in Milan, Italy.  BI-MU is an exhibition dedicated to the Italian machine tool, robot, and automation industries.  And, our distributor is very keen on finding relevant applications and solving problems in these industries.

One of the most frequent applications we discussed was the use of the Adjustable Spot Cooler.  During milling operations or in lathe turning applications, considerable heat is generated when the cutting edge is applied to the work piece.  This heat can cause the metal (or other material being machined) to adhere or even weld to the cutting edge or flute of a bit.  Such a  condition presents quality control problems, and loss concerns due to machine tool downtime.

The Adjustable Spot Cooler can remove these problems from a machining application using only compressed air – no liquid.  By directing extremely cold air (as low as -30F) to the machining area, the heat is removed and the useful time of the cutting edge is in increased.  By cooling the precise area generating the heat, the Adjustable Spot Cooler can boost the productivity and quality of parts coming out of a machine.

If you have a similar application, or think an Adjustable Spot Cooler may be a positive addition to your application, contact an EXAIR Application Engineer.
