Box Cooler

Nex Flow™ Vortex Tubes are available in a wide range of sizes to meet the needs of many process andspot 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° Fahrenheit, and the hot side can be adjusted up to a temperature of 250° Fahrenheit.



    Vortex Tube Advantages:

    • 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
    • Why Our Vortex Tubes:

      Our Vortex Tube are Stainless Steel with metal generators as standard for use in high temperature environments No extra charges as with some competitors Superior performance and design

How Box Cooler Works




Compressed air enters at point (A) into the vortex tube.The vortex tube splits the compressed air into a hot (B) & cold (C ) stream of air. The hot air from the vortex tube is vented to the atmosphere at point (D). Hot air displaced from the box is vented out through the breather cap (E). Cold air enters the box at point (F) or via an optional hose distribution kit (G).


Applications

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

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 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.
