Model 3225 vortex tubes were supplied to a major appliance manufacturer to reduce the rejection rate caused by thin corners in refrigerator shells.

The manufacturer vacuum-formed the plastic interior shell of refrigerators. However the deep draw of the plastic and complex geometry left the four corners unacceptably thin, resulting in tears during assembly or bulging when insulation was inserted between the shell and exterior housing.

Model 3225 vortex tubes were positioned to cool the critical corner areas just prior to forming the plastic sheet. By cooling these areas, less stretching of the plastic occurred, which resulted in thicker corners.

Model 3225 vortex tubes offer the ideal cooling solution for manufacturing processes with their ability to supply ‘instant’ cold air down to -46°C from an ordinary compressed air supply. Along with cooling other vacuum formed parts such as spas, bathtubs, tote pans and waste cans, the vortex tubes are ideal for cooling hot melts, ultrasonic welders and environmental chambers.

Model 3225 vortex tubes are available from Compressed Air Australia .
