Closed Pressurized Expansion Tank

Closed Pressurized Expansion Tank 

The Closed Pressurized Expansion Tank is an essential component designed to maintain pressure stability and compensate for thermal expansion in closed water heating and cooling systems. Engineered with durable mild steel construction and a high-quality internal diaphragm or bladder, this tank ensures efficient pressure control, system protection, and extended equipment lifespan.

The closed design prevents water contact with air, minimizing corrosion and oxidation, while the pressurized air cushion absorbs excess water volume during temperature fluctuations.
