This high-performance expansion tank is engineered to effectively absorb the expansion forces of heating and cooling system water, ensuring your hydronic circuit maintains consistent pressure under varying operating loads. The 116298 Bell & Gossett Series D-15 expansion tank is designed as a heavy-duty, pre-charged diaphragm-type pressure vessel, providing a reliable buffer to prevent relief valve discharge and component wear.
Inside the tank, a flexible heavy-duty diaphragm separates the system fluid from a pre-charged air cushion. As the water in your hydronic system heats up and expands, it pushes against the diaphragm, compressing the air in the sealed chamber. This precise mechanism compensates for volume changes caused by thermal fluctuation, protecting your system's piping, pumps, and boilers from excessive stress.
Key System Performance Baselines:
- ASME Rated Safety: Constructed to rigorous standards for pressure vessel integrity and reliability.
- Diaphragm Separation: Utilizes a high-grade flexible barrier to prevent waterlogging and reduce tank corrosion.
- Pressure Stabilization: Effectively maintains optimal system operating pressure during thermal expansion cycles.
⚠️ Application Profile: Ideal for commercial and industrial closed-loop hydronic heating systems, chilled water circuits, and large-scale thermal management installations requiring dependable volumetric expansion control.
