JVC Series Condensate Return

JV Series units produce a powerful vacuum that allows boilers to operate at a lower pressure, minimizing heat loss and reducing heating costs. Units are available in simplex, semi-duplex, and duplex models. JVC Series Vacuum/Condensate Return units collect and quickly return condensate to the boiler feed unit using various designed pressures and flows. Pumping action is controlled by the water level inside the receiver and uses either a standard float switch or a mechanical alternator to turn the pump(s) on and off. The water passes through a Venturi, creating a powerful vacuum that aids in air removal from the system and allows steam to travel long runs.
