Negative Pressure Unit | Stop Leaks | Temperature Control

VT-1800

These units are closed circuit negative pressure temperature control units with heater, heat exchanger and stainless steel reservoir. The design features a vacuum venturi that creates the best air separation in the industry. The Vac-U-Temp stop leaks without robbing your pump of pressure that can reduce the usable flow of the system. It is an excellent choice in a closed loop system requiring both heating and cooling for mold or process temperature control.
