Boiler Expansion Tanks
Bell & Gossett expansion tanks absorb the force of thermal expansion in hydronic heating and potable domestic water systems. The butyl diaphragm separates system water from the air in the tank thereby preventing water-logging problems. Bell & Gossett HFT tanks are for standard hot water heating systems (for heating the home or building environment). Bell & Gossett PT tanks are for potable domestic water systems (water heated for showers, bathrooms, laundries, etc.). The PT tanks use a polypropylene liner to protect the water from contaminants. ASME designated PT tanks can be special ordered -- Call the phone number above for price and availability.
