Amtrol Fill-Trol FT-110 4.4 Gallon In-Line Hydronic Expansion Tank

Amtrol 389780 Details

Prevent dangerous thermal expansion with this Amtrol Fill-Trol FT-110 4.4 gallon in-line hydronic expansion tank. This tank is designed for use in closed, non-potable, hydronic heating and chilled 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/EPDM, 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. It can be used for propylene glycol applications with mixtures up to 50%. It comes equipped with an automatic fill valve to control the system pressure. This eliminates the need for a separate, automatic fill valve.

This tank has an outer shell made of durable steel with a urethane topcoat for additional strength. It has a maximum operating temperature of 240 degrees Fahrenheit and a maximum working pressure of 100 PSIG. Plus, it has an ample 4.4 gallon capacity. This unit features an In-Sight indicator cap that changes color to alert users that tank service is required. It comes pre-charged with a 12 PSIG air charge, and it has a 1/2" NPTF water connection. It uses convenient in-line mounting to save space.
