Adjustable Spot Coolers
The Frigid-X™ Adjustable Spot Cooler is adjustable in both temperature and flow. The temperature is adjustable using a knob at the hot end to set the temperature precisely to your requirements from approximately minus 30ºF to room temperature. Three precision brass generators come with the system for flow rate adjustment – providing refrigeration from 700btu to 2100 BTU/hr. Nex Flow™ Frigid-X™
Vortex Tubes normally come with an adjustable hot end that requires screwdriver to change the setting. If the application requires an easier adjusting mechanism the Hand Adjustable version is available. For the small and medium sized vortex tubes. It comes with a built in hot end muffler for noise reduction and is made if stainless steel. The Hand Adjustable assembly may also be purchased separately to convert the standard Vortex Tube into a hand adjustable version. Inside the vortex tube is the interchangeable brass generator which determines the air flow capacity.
There are two types – one to product extreme cold temperatures (maximum cold temperature out call the C generator) and one type to produce the maximum amount of cooling (maximum refrigeration called the H generator). The Hand Adjustable units are used only with the H generators.

Setting Flow and Temperature
The hand adjustable knob 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.
A muffler is incorporated into the hot end hand adjustable system. A cold end muffler is also available.
