Xylem-Bell & Gossett 116664 40-Gallon Compression Tank ASME

The Xylem-Bell & Gossett 116664 40-Gallon Compression Tank ASME is a pressure system vessel used to absorb water volume changes in closed-loop hydronic systems during heating or cooling operation. It contains an air cushion that accommodates expansion as system water temperature rises, supports to maintain operating pressure throughout the loop. This tank is installed in boiler, chiller, and circulating water systems where pressure control is needed to support fluid movement and equipment protection. It supports balanced system pressure, reduces stress on connected components, and supports to performance in commercial water-based applications and HVAC systems.
