NEVER ACOMPROMISE FOR QUALITY OR SAFETY

The return system is standardly
recommended with high pressure
steam boilers to supply water
with a boiler feed pump that
operates on demand from the
boiler water level control.

The tank provides storage
for water make-up and
return condensate from the
system when available with
the advantage of pre-heated
water. The tank is also used
for convenience of feeding
water treatment to the boiler.
