Thermolator® vacuTrac


Control Temperature and Stop Mold Leaks

Keep your operation up and running with the Thermolator® vacuTrac water temperature controller. This positive/negative pressure unit can be used as a temporary fix for a leaky mold or bad O-rings.

The vacuTrac is equipped with a manual three-way ball valve that allows you to change the unit from positive pressure to negative pressure by moving the valve handle on the back of the unit counterclockwise. Changing the unit to operate with negative pressure allows the unit to draw air into the mold, effectively stopping leaks.
