116493 Bell & Gossett D40V Expansion Tank

Datasheet

Series “D” expansion tanks are ASME rated precharged diaphragm-type pressure vessels. The Series “D” tank is designed to absorb the expansion forces of heating/cooling system water while maintaining proper system pressurization under varying operating conditions. The heavy duty diaphragm separates system water from the tank air charge thereby eliminating waterlogging problems.

Pre-charged Expansion Tanks contain either a bladder or a diaphragm to separate the air charge from the system water. Tanks are design to absorb the expansion forces of heating/cooling system water while maintaining proper system pressurization under varying operating conditions.
