Thermal Expansion Tanks
Silver Springs Thermal Expansion Tanks are built for durability and efficiency, featuring an FDA-grade liner and butyl rubber diaphragm to absorb expanding water, relieve system pressure, prevent corrosion, and ensure safe, potable water with high-quality materials and patented technology.
Description
Our Thermal Expansion Tanks feature an FDA Grade liner, a fixed butyl rubber diaphragm and are precharged at the factory with 35PSI. The tanks are designed to absorb heated water as it expands in the system.
The tank protects the plumbing system by allowing the expanded water to enter the tank, thereby relieving pressure on the piping of the system. When water enters the tank, it is contained inside an FDA-Grade polypropylene liner, thus protecting the water from coming into contact with the steel of the tank. This helps keep the water potable and protects the tank from corrosion.
