120 VAC PROGRAMMABLE UNIVERSAL - Residential Steam Boiler Water Feeder

The VXT is the first automatic steam boiler water feeder designed to monitor the amount of water added to a steam boiler. The addition of make-up water raises the oxygen level in a boiler and accumulates lime and other mineral deposits. Excessive boiler make-up water can cause cast iron boilers to rust internally, severelyshortening the boiler's life. Mineral deposits from too much make-up water can impede heat transfer causing cast iron boiler sections to overheat and crack. Unlike other water feeders, the VXT can protect the life of a boiler by exposing system leaks that call for excessive make-up watergiving you the information you need to diagnose and repair the system before it's too late. VXT Steam Boiler Water Feeders are primarily used on residential and light commercial steam heating boilers up to 500,000 Net BTUH. They are not recommended for commercial steam process work. The VXT feeder should be wired to and receive its signal from a float or probe type low water cut-off. When the VXT receives a signal from the LWCO, it initiates an adjustable delay before feed to allow condensate from the system to return to the boiler and near boiler piping. Upon completion of the delay, if the LWCO feed signal is still present, the feeder begins its feed cycle. If the feed signal is still present after the completion of the feed cycle, the control will revert back to its delay mode. After the second delay expires the control will begin another feed cycle. If the signal is still present after the second feed cycle, the control will lock-out until the feed signal from the LWCO has been removed. Once in lock-out, the feeder can be forced to feed an additional two cycles each time power is removed then reapplied. The Safgard VXT water feeder is fully programmable to accommodate any residential steam system.
