Vortex Tube, Frigid-X Vortex Tube, Vortex Tube - Frigid-X™, Vortex Tube - Stainless SteelProduct Overview

      • Nex Flow™ Vortex Tubes are available in a wide range of sizes to meet the needs of many process and spot cooling applications.

      • Vortex Tube Information

        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 -50 degrees Fahrenheit, and the hot side can be adjusted up to a temperature of 250 degrees Fahrenheit.

      • Vortex Tube Advantages:

        Use the Hand Adjustable Hot End System complete with incorporated Hot End Muffler

 

How They Work

  • The liquid is cooled by means of a small vortex tube that uses around 5 SCFM (142 SLPM) at a maximum of 50 psig (3.5 bar). Pressure can be adjusted up or down slightly to avoid freezing of the liquid or to get a colder temperature.

    An adjusting screw controls the level of mist required. Liquid is siphoned into the unit using a long plastic tube connected to the main unit. A heavy duty removable magnet secures the Sub-Zero Tool Cooling Mist System onto a machine. The magnet can also be removed and mounting holes may be used to secure the mist system.

    All you need is the liquid to cool and/or lubricate and a small amount of filtered (clean) compressed air at 50 psig (3.5 bar). No electrical components, no expensive pumps or moving parts except for the adjusting screw assures long life and maintenance free operation.

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.
