TANKS HFT Diaphragm Tanks • Expansion Tanks for Hydronic Heating
Airtrol
®
Tank Fittings
Directs free air to the compression tank. Restricts thermal
circulation to boiler. Establishes initial tank air level.
Allows compression tank size reduction.
Description
Bell & Gossett HFT expansion tanks
are designed to absorb the force
of thermal expansion in hydronic
heating systems. Series HFT tanks
for hydronic heating systems are
available in sizes from 2—86 gallons.
The Series HFT tank is designed
to absorb the force of thermal
expansion of heating water to
maintain proper pressurization in a
closed hydronic system. The heavy
duty butyl diaphragm separates
system water from the air in the tank
preventing water logging problems.
