110 | Expansion Tank Fill-Trol Automatic Fill 4.4 Gallon 100 Pounds per Square Inch Gauge 1/2" NPT 110 for Closed Loop Hydronic Heating and Radiant Heating Applications | Amtrol

Amtrol Expansion Tank Fill-Trol Automatic Fill [sku]: This Amtrol Fill-Trol system combines an EXTROL pre-pressurized expansion tank and a specially designed, automatic fill valve. It accepts expanded water when the system temperature rises to reduce pressure build-up, eliminating the need for a separate fill valve. Its adjustable settings help reduce energy consumption and system wear, while the automatic air vent eliminates system air. The air purger efficiently separates air from water. The system connection sets the point of no pressure change, and the water-tight reservoir stores expanded water. The sealed air cushion, precharged and tested at the factory, maintains precharge settings. The strong, deep-drawn steel tank and projection welded air stem ensure durability. The tank pressure controls system fill, and the spring-loaded check valve and automatic shut-off valve spring guarantee reliable operation. Equipped with a removable strainer, cold water supply, expansion bypass, fill gate stem, and more, this expansion tank fill-trol is perfect for closed loop hydronic heating and radiant heating applications.Midwest supply - We offer the best prices and fast shipping for your products!
