Hydronic Expansion Tanks
hydronic expansion tanks are a primary device when it comes to pressurizing and maintaining pressure in a closed system. These tanks are also commonly referred to as hydro-pneumatic expansion tanks. The tanks we supply are manufactured by the globally renowned Zilmet company which is based out of Italy but has stock in the USA. Zilmet hydronic expansion tanks offer superior performance, operation, and durability, they also feature a strategically placed side connection for quicker and less expensive installation. These tanks also have a compact design with a seamless diaphragm that never stretches or creases. There are no bubbles or corners to trap sediment, which inhibits bacterial growth.
