Stainless Steel Vortex Tubes Large H Series Nex Flow Model 50150H
Our Vortex Tube is a tool that can take normal compressed air and convert into two air streams. One stream is hot air and the other stream is cold air. The advantage of our vortex tube is that it has no moving parts , which translates into no maintenance. The cold air can be adjusted down to -50º F, and the hot side can be adjusted up to a temperature of 250º F.
Sizes Of Vortex Tubes
There are three basic physical sizes of vortex tubes used extensively in industry the small version, medium version and large version. Vortex tubes can be selected by required performance in cooling for the "H" generator versions and where very cold temperatures are required "C" generators are used. However, even with "C" generators, as expected, the higher the flow rating the greater the cooling effect.
Nex Flow stainless steel vortex tubes use a metal (brass) generator as a standard item rather than cheap plastic for longer life and for applications in high temperature environments. (competitors would charge extra for that feature.) With virtually no moving parts, Vortex Tubes take compressed air and converts it to cold air at one end and hot air at the other. Temperature as low as -50ºF (-46ºC) can be achieved at the cold end and up to 260º F (127ºC) at the hot end.
Vortex tubes are used to cool electronic controls, machining operations, spot cooling and more.
How Do Stainless Steel Vortex Tubes Large H Series Nex Flow Model 50150H Work?
Compressed air enters at point (A). Inside the vortex tube the compressed air is made to spin using a generator. It travels in one direction along the small (hot end) tube and then back inside itself in the reverse direction creating one stream of air (B) and the second stream of air (C) in the opposite direction. The outside stream of air gets hot and exhausts at point (D). The centre column of air gets cold and exists at point (E). Temperatures and capacities can vary by adjusting the hot end plug at (D) and by using different generators
Why Nex Flow Vortex Tubes?
Our vortex tubes are stainless steel with metal generators as standard for use in high temperature environments. Superior performance and design. In addition, it is useable in high temperature environments AS IT COMES with NO extra charge unlike many of our competitors.
Most competitors use plastic generators and standard Buna N O-Rings and charge extra for brass and viton. The unique design and quality of materials used in Frigid-X vortex tubes will deliver years of maintenance-free operation.
Do you require a more convenient way to adjust the vortex tube?

Stainless Steel Vortex Tubes Large H Series Nex Flow Model 50150H Applications
They are used in the following applications.
Setting Flow and Temperature In Frigid-X Vortex Tubes
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-X50000C series. However, mufflers are available for both the cold and hot ends if required.
