The Honeywell Domestic Hot Water Expansion Tank boasts a 4.4-gallon volume with a steel shell for durability. This expansion tank is designed with a 3/4 in. Male NPT, measuring 11 inches in diameter and 12-5/8 inches in height. It guarantees a minimum acceptance volume of 3.2 gallons. The relative lightweight of 5 lbs combined with materials such as a robust brass connection, a polypropylene liner, and a butyl diaphragm ensures solid construction. This sturdy build ensures performance reliability in industrial settings.

This tank features a high-quality, FDA-approved, heavy-duty butyl rubber diaphragm that efficiently isolates water from air, ensuring the precise operation of the system. The polypropylene liner serves as a fully non-metallic, non-corrosive water reservoir, adding to the tank's longevity. This can prevent occurrences of water hammer— a critical factor for maintaining smooth system operations.

The Honeywell Domestic Hot Water Expansion Tank is maintenance-free, making it a convenient choice for several industrial applications. Its design helps protect the water heater from damaging pressure cycling, enhancing equipment life. Moreover, the efficient design of the tank allows the storage of expanded water without any increase in system pressures. This feature aids in preserving system integrity and preventing unnecessary wear and tear. Thus, it ensures the prolonged, efficient functionality of your Honeywell-based control systems.
