Condensate Return/Boiler Feedwater System
Manage Condensate for Efficient Operation
Precision Boilers’ Model CF boiler feed systems are designed to receive condensate, accommodate condensate surges, and, when condensate return is insufficient, automatically add make-up to maintain sufficient boiler or deaerator water supply. Standard receiver tanks are vented (non-code) and are constructed of hiqh quality 1/4″ thick carbon steel.
Make-up valves are either internal or external float-operated to maintain a minimum water level. Systems can be supplied with single or multiple pumps (with starters and controls), plus optional items such as alternators, alarm systems, auto standby provision, sparge-tube preheat system, makeup water spray valve, special tank materials/linings, etc.
