Description
The Bell & Gossett 116051 B200 is a heavy-duty pressurized expansion tank engineered for demanding closed-loop hydronic heating and cooling systems. With a generous 53-gallon capacity, this tank effectively absorbs system pressure fluctuations, protecting pumps, boilers, and piping from the damaging effects of thermal expansion.
Durable Construction
Built for long-term reliability in commercial and industrial hydronic applications, the B200 features a robust carbon steel shell designed to withstand the rigors of pressurized system environments. The interior is fitted with a heavy-duty butyl rubber bladder that fully separates the system fluid from the pre-charged air cushion, preventing waterlogging and maintaining consistent system pressure over time.
