Cooling Turn Rolls

Customer needed a way to cool guide bars. They processes mylar sheets. In the process, the sheets pass over the tubular steel bars that act as guides. The friction is causing the bars to heat up and affects the mylar. The heat is causing the mylar to stretch and tension settings are disrupted causing jam ups.

I suggested blowing refrigerated air through the inside of the bars with a Model 3230 Vortex Tube.  This eliminated any heat build up and registry was maintained throughout the shift.
