The table shows approximate temperature drop and rise achieved by Vortex Tubes when adjusted to various Cold Fraction. A Cold Fraction is the percentage of cold air produced versus total filtered compressed air consumed by any Vortex Tube.

Table baseline: Compressed air temperature: 21 C.

Pressure Dew Point: -56 C (dry air).

Backpressure: not to exceed 0.4 bar (5 PSIG).

TD: Temperature Drop.

TR: Temperature Rise.
