The VXT is the first automatic steam boiler water feeder designed to monitor the amount of water added to a steam boiler. The addi- tion of make-up water raises the oxygen level in a boiler and accu- mulates lime and other mineral deposits. Excessive boiler make- up water can cause cast iron boilers to rest 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. Un- like any other water feeder, the VXT can protect the life of a boiler by exposing system leaks giving you the information you need to diagnose and repair the system before it’s too late.
