The new 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 torust internally, severely shortening 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 water - giving you the information you need to diagnose and repair the system before it's toolate.
