Description
The Zilmet ZETA-20 Hydro Expansion Tank is a 10.9 gallon pressure control part that is used to control thermal expansion in closed-loop heating and cooling equipment. It works by using an internal diaphragm which separates air and water so that expanded fluid volume can be absorbed without changing the system pressure. It is typically installed in HVAC systems like hydronic heating or boiler-based systems in either a commercial or residential installation, and is linked in system piping in the vicinity of the heat source. Its operation aids pressure stability, aids in stress protection of components and ensures stable performance of the system.
