RV Series Positive/Negative Pressure Temperature Controller

Vactherm RV Series positive/negative temperature controllers eliminate downtime caused by a coolant leak in the mold or process water circuit. The unique design of the Vactherm allows the vacuum level to be adjusted to the exact amount necessary to stop the leakage, without drawing air into the water circuit. This provides better temperature control at lower flow rates than competitive designs. Plus units can run as nonferrous temperature controllers even when no leak is present.
