Generically, a Buffer or Volume tank is one that is installed to add extra capacity to any system that contains fluid. Hanson tank manufactures buffer tanks for both hot and chilled water systems. Their purpose is to increase the volume of water in the system to achieve optimum efficiency. It is usually insulated to reduce unwanted heat transfer. Hanson Buffer tanks are normally vertical and as they are for indirect closed loop systems, are usually unlined. Without a buffer tank, rapid fluctuation of water temperature causes frequent stops and starts ("short cycling") of the equipment.
A correctly sized and located thermal buffer tank significantly improves the performance and longevity of the entire system it is installed in. Hanson can manufacture any style of cylindrical buffer tanks in carbon or stainless steel. Buffer tanks 42” OD and above have a 12” x 16” manway.
