Amtrol 390654 Details

Prevent dangerous thermal expansion with this Amtrol Therm-X-Span T-12 4.4 gallon in-line thermal expansion tank. This tank is designed for use in closed, potable water systems. It accepts expanded water as the system temperature increases, which activates the diaphragm to keep pressure below the valve setting. This diaphragm is made of heavy-duty butyl, and it also helps separate the system water from the tank's air charge. This handy tank saves energy, eliminates potential safety hazards, and reduces system maintenance.

This tank has an outer shell made of durable steel with a urethane topcoat for additional strength. It has a polypropylene liner to protect the interior of the tank. This unit has a maximum operating temperature of 200 degrees Fahrenheit and a maximum working pressure of 150 PSIG. It has an ample 4.4 gallon capacity, and it can be paired with multiple units to accommodate larger systems. It comes pre-charged with a 40 PSIG air charge, and it has a 3/4" NPTF water connection. This tank uses convenient in-line mounting to save space.
