Vortex Tubes MOBILE VIEW Vortex Tubes Cold air to -50°F (-46°C) from your compressed air supply — with no moving parts! What Is A Vortex Tube? A low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. Using an ordinary supply of compressed air as a power source, vortex tubes create two streams of air, one hot and one cold, with no moving parts. Vortex tubes can produce: • Temperatures from -50° to +260°F (-46° to +127°C) • Flow rates from 1 to 150 SCFM (28 to 4,248 SLPM) • Refrigeration up to 10,200 Btu/hr. (2,989 Watts) Temperatures, flows and cooling...

Vortex Tubes How A Vortex Tube Works Compressed air, normally 80-100 PSIG (5.5 - 6.9 BAR), is ejected tangentially (1) through a generator into the vortex spin chamber (2). At up to 1,000,000 RPM, this air stream revolves toward the hot end (3) where some escapes through the control valve (4). The remaining air, still spinning, is forced back through the center of this outer vortex. The inner stream gives off kinetic energy in the form of heat to the outer stream and exits the vortex tube as cold air (5). The outer stream exits the opposite end as hot air (6). There is a detailed discussion of...

Vortex Tubes Selecting The Right Vortex Tube EXAIR Vortex Tubes are available in three sizes. Each size can produce a number of flow rates, as determined by a small internal part called a generator. If Btu/hr. (Watts) requirements, or flow and temperature requirements are known, simply select the appropriate vortex tube according to the specification information shown below or the performance tables shown on the following page. Keep in mind that the vortex generators are interchangeable. If, for example, a Model 3215 Vortex Tube does not provide sufficient cooling, you need only change generators...

The Vortex Tube Performance Tables below give approximate temperature drops (and rises) from inlet air temperature produced by a vortex tube set at each cold fraction. Assuming no fluctuation of inlet temperature or pressure, a vortex tube will reliably maintain temperature within ±1°F. Pressure Supply Cold Fraction % Numbers in shaded area give temperature drop of cold air, °C. Numbers in white area give temperature rise of hot air, °C /ortex es • Spot Cooling Back Pressure: The performance of a vortex tube deteriorates with back pressure on the cold air exhaust. Low back pressure, up to 2 PSIG...

Vortex Tubes Cooling Vacuum Formed Parts The Problem: A manufacturer of major appliances vacuum forms the plastic interior shell of refrigerators. The deep draw of the plastic and complex geometry left the four corners unacceptably thin. The corners would tear during assembly or bulge when insulation was inserted between the shell and exterior housing, resulting in a high rejection rate. The Solution: (4) Model 3225 Vortex Tubes were positioned to cool the critical corner areas just prior to forming the plastic sheet. By cooling these areas, less stretching of the plastic occurred which resulted...

Vortex Tubes Cooling Blow Molded Fuel Tanks The Problem: Automobile fuel tanks are blow molded, then clamped to a fixture to prevent distortion during the cooling cycle. The cooling time of over 3 minutes required for each tank created a bottleneck in the production process. The Solution: (2) Model 3250 Vortex Tubes were mounted to the cooling rack and connected to a compressed air line. Cold air produced by the vortex tubes was circulated inside the fuel tanks. Cooling time was reduced from three minutes to two minutes for each tank, improving productivity by 33%. Comment: It’s hard to imagine...
