The basic vortex tube has been utilized in numerous industrial cooling applications over the years. Some of these applications have gained such popularity that they have led to the creation of specialized “applied products” tailored to meet specific needs. These products encompass the Adjustable Spot Cooler, Mini Cooler, Cold Gun, and Cabinet Coolers, all of which are available in our catalog and on our website.

The Mini Cooler utilizes a vortex tube to transform a limited quantity of compressed air into two low-pressure streams that flow in opposite directions, one within the other. This interaction allows the two air streams to exchange heat, resulting in the generation of cold air at one end of the tube and hot air at the other. A flexible hose channels the cold airstream towards the surface intended for cooling.

Heat produced by processes like machining, welding, soldering, brazing, electrical losses, and the functioning of rotating or reciprocating machinery poses considerable challenges that extend beyond simple comfort. Efficient heat removal from these activities is crucial for uninterrupted operation, as significant amounts of heat often require dissipation. For example, power plants generating electricity employ large pumps to circulate thousands of gallons of water each minute through extensive heat exchangers, which condense steam from turbines, enabling reheating and sustaining turbine functionality.

The Mini Cooler operates on the Vortex Tube principle to produce cold air from compressed air without any moving components, providing immediate cooling on demand. This method relies on a physical phenomenon rather than direct heat transfer, allowing the Mini Cooler to deliver cold air at specified flow rates and temperatures as soon as compressed air is supplied. It can be activated or deactivated as frequently as required, and its design eliminates the risk of wear from moving parts or failure of electrical components. With a compressed air requirement of just 8 SCFM at 100 psig, even relatively small compressors, some as low as 3HP, can sustain continuous operation of the Mini Cooler.
