AMTROL 435465 THERM-X-TROL ST-60VC 25GAL 150PSI POTABLE ASME EXPANSION TANK

MFR Part #: 146-776
SKU #: 1115627
Brand: Amtrol®
UPC: 14045354653
Amtrol® THERM-X-TROL® 146-776 ST-60VC Diaphragm Thermal Expansion Tank, 25 gal Capacity, 0.44 Acceptance, 150 psi Pressure, Heavy Duty Butyl Diaphragm, 16 in Dia x 32 in H
1 Year Limited
Closed potable water systems to control pressure build-up
ANSI/NSF61 | ASME VIII | Division 1 Standards | IAPMO Listed | NAF 2016 Compliant | SBCCI

Amtrol® THERM-X-TROL® Diaphragm Thermal Expansion Tank, Series: ST-60VC, 25 gal, 16 in Dia, 32 in Height, 150 psi, Acceptance Factor: 0.44, 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.
