Frigid-X™ Vortex Tube/Hilsch Tube - Stainless Steel
Setting Flow and Temperature in Vortex Tube/Hilsch Tube:
Adjusting the slotted valve at the hot air outlet sets the flow rate and temperature at the cold end. The more air let out at the hot end reduces the cold air flowing and the cold air temperature at the cold end. Close the valve at the hot end and you increase the cold air flow at the cold end as well as the air temperature at the cold end. The percentage of total input air to the vortex tubes that is directed to the cold end is the "cold fraction". A cold fraction of 60% to 80% produces the optimum refrigeration. See the chart below which indicates the temperature "rise" at the hot end and temperature "drop" at the cold end of a vortex tubes at various input pressures and "cold Fraction" setting.
Most industrial applications, such as electrical control panel cooling, parts cooling, tool cooling require maximum refrigeration and utilize the Nex Flow™ Frigid-X™ 50000H series. Applications which require extreme cold temperatures such as lab sample cooling, circuit board testing, would utilize the Nex Flow™ Frigid-X™50000C series. However, mufflers are available for both the cold and hot ends if required.
