There are several ways to determine the cold fraction setting of your Vortex Tube. One would be to use the performance data chart in the EXAIR Catalogue and on our website that displays the temperature drop and rise of the Vortex Tube at various temperatures and supply pressures. Measure the temperature of the cold air exiting the Vortex Tube and compare it to the chart. Ensure that the air temperature is measured immediately out of the Vortex Tube as the air stream will warm as it mixes with ambient air.

Another method is to use an air flow meter to measure the volume of air both going into and out of the unit and comparing the hot and cold flow rates of the unit. Comparing the hot or cold flow rate to the total will give you the relative cold or hot fraction setting.
