Amtrol® THERM-X-TROL® Diaphragm Thermal Expansion Tank, Series: ST-30VC, 14 gal, 16 in Dia, 19 in Height, 150 psi, Acceptance Factor: 0.64, 200 deg F, Heavy Duty Butyl Diaphragm, Steel Shell, Red Oxide Primer, Domestic
The THERM-X-TROL is designed to provide control of maximum system pressures at a level below the relief valve setting. It also provides an additional space in the system to accommodate the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded. Maximum pressure is kept well below the relief valve setting by the THERM-X-TROL, with its pre-charged air cushion that is separated from system water. The relief valve does not open, therefore "spillage" is eliminated.
