Programmable Water Feeder
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 to rust
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 too late.

Universal Compatibility
The VXT can be used with virtually any probe or float-type
low water cut-off. It is available in 120 VAC (Model VXT-120)
and 24 VAC (Model VXT-24).
Digital Feed Counter
Brightly illuminated feed counter displays
the amount of water added to the boiler –
essential in diagnosing water loss problems
that can severely shorten the life of a steam boiler. Built-in
memory prevents power interruptions from clearing the
counter.
Programmable Feed Delay Settings
Helps prevent flooded boilers.
Allows time for condensate
to return to the boiler
before starting feed
cycle – ensuring that
additional water is
needed.
Programmable Feed
Amount Settings
Six settings provide two
ways to feed. 1-5 gallon set-
tings now feed above the low
water cut-off to restore the boiler’s
normal operating level. Or, select LWCO setting to end the
feed cycle when the low water cut-off re-energizes the
burner circuit.
Manual Feed Button
Allows for additional make-up water at the touch of a button.
Manual feed amounts are recorded and added to the total
gallons displayed by the feed counter.
Underfeed Protection
If one feed cycle is not sufficient to restore boiler operation,
the VXT will delay and feed one additional cycle.
Lockout Flood Protection
The VXT locks-out to prevent steam system flooding and
costly water damage if burner operation does not resume
after two consecutive feed cycles.
