Vortex Tubes

Vortex Tubes are an effective, low-cost solution to a wide variety of industrial spot and process cooling needs.

Overview

Nex Flow™ Vortex Tubes are an effective, low-cost solution to a wide variety of industrial spot and process cooling needs. Available in three basic sizes Small, Medium and Large and in several packaged versions.

Our Stainless Steel vortex tube comes assembled with a brass generator as a standard item rather than cheap plastic for longer lifespan and for applications in high-temperature environments. With virtually no moving parts, the vortex tube takes compressed air and converts it to cold air as low as minus 50° F (minus 46° C) at one end and hot air at the other up to 260° F (127° C).

Frigid-X™ Adjustable Spot Cooler

The Frigid-X™ Adjustable Spot Cooler is a low cost and maintenance free Adjustable Spot Cooler system which utilizes a vortex tube to produce cold air at one end.

Frigid-X™ Mini Spot Cooler

The Nex Flow™ Mini Spot Cooler is designed for small parts and produces a stream of 15 to 20 degree F (minus 9.5 to 7 degree C) of cold air to prevent heat buildup depending on inlet air temperature.

Frigid-X™ Box Cooler

For cooling small enclosures for laboratory use, environmental chambers and any application where an enclosure needs cooling

Applications

  • Cool electronic and electrical control
  • Cool machine operations/tooling
  • Cool CCTV cameras
  • Set hot melt adhesives
  • Cool soldered parts
  • Cool gas samples
  • Cool heat seals
  • Cooling environmental chambers

Adventages

  • No moving parts, reliable, maintenance free
  • No coolant
  • Compact and lightweight
  • Low cost application
  • Maintenance free units
  • Instant cold air in environmental chambers
  • No spark or explosion hazard
  • Interchangeable generators

Temperature

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 Frigid-X™ 50000H series. Applications which require extreme cold temperatures such as lab sample cooling, circuit board testing, would utilize the Frigid-X™50000C series. However, mufflers are available for both the cold and hot ends if required.

**Approximate temperature drops (and rises) from inlet air temperature produced by a Vortex Tube set at various cold fractions. Assume constant inlet pressure and tempereture. Tests were conducted with a 15H generator in a medium size Vortex Tube (Model 50015H). Will vary with other sizes and capacities**
