Amtrol ST-60V Thermal Expansion Tank

The Amtrol ST-60V Thermal Expansion Tank is a vertical stand unit designed for reliable pressure management in closed potable water systems. This 34-gallon tank features 22" diameter by 30" height with 3/4 inch female threaded inlet/outlet connections for easy integration.

Constructed with a urethane top-coated steel tank and an antimicrobial inner lining, it protects water quality while resisting corrosion. The heavy-duty butyl diaphragm, factory pre-charged air at 40 PSIG, and a temperature rating up to 200°F with a pressure rating up to 150 PSIG ensure durable expansion control in potable applications.

Designed to meet industry standards, it is IAPMO R&T and NSF/ANSI 61 compliant, ISO 9001 certified, and lead-free. The closed potable water system benefits from built-in features like a projection welded air valve, turbulator water circulator, and stainless steel system connection.
