Accept. Volume (Gallons) - 11.3 A Height (Inches) - 23 B Diameter (Inches) - 15-3/8 System Conn. (NPTF) - 1/2 Maximum Working Pressure = 100 PSIG Maximum Operating Temperature = 240 F Factory Precharge = 12 PSIG How the Amtrol FILL-TROL 112 Expansion Tank System Works: Water enters the FILL-TROL valve pushing open the check valve and flows into the heating system. The automatic shut-off valve is kept open by the diaphragm pressing against the pressure plate raising the stem of the fill gate which compresses the automatic shut-off valve spring. When the heating system reaches fill pressure (12 psig) the tank's diaphragm depresses and the automatic shut-off valve is closed. Whenever system pressure falls below 12 psig the automatic shut-off valve is pressed open by the diaphragm. Make-up water flows into the system to restore pressure.

Amtrol ST-25V THERM-X-TROL Expansion Tank 10.3 Gallon (143N164) What Is Thermal Expansion? With modern plumbing codes mandating backflow prevention thermal expansion can cause pressure buildup in domestic water systems. When demand is put upon a potable water system hot water is drawn from the water heater. Cold water from the supply line enters the water heater to replenish it. The colder water is heated to replace the hot water used. With the installation of a backflow preventer check valve or pressure reducing valve on the supply line the water heater and the system piping form a closed plumbing system under pressure. As the water is heated thermal expansion occurs. Pressure increases until the relief valve opens and the expanded water "spills" from the water heater. This "spillage" results in wasted BTU's and a potential safety hazard for the homeowner. Closed Potable Hot Water system without THERM-X-TROL Backflow preventer pressure reducing valve or meter causes expanded (heated) water to build pressure causing the relief valve to open resulting in: Wasted BTU's Shortened water heater life Wasted municipal water and sewer dollars Potential safety hazard for homeowner The Amtrol THERM-X-TROL ST-25V Expansion Tank is designed to eliminate this problem by providing control of maximum 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. Closed Potable Hot Water System with THERM-X-TROL Expanded (heated) water is absorbed by THERM-X-TROL which means: Water heater and fixtures are protected Eliminates BTU and water waste saving money and energy No dangerous
