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.
