For pressurisation, deaeration and topping up in sealed heating installations (acc. to EN12828) and chilled water (cooling) installations.

Sinums with pump units are used for storage of expansion water, deaeration and topping up your installation automatically as an integrated controlled unit carried out with state of the art micro-electronics. The Sinum balanced pressure expansion equipment is sized according to the total system volume and the boiler or chiller load. The Sinum vessel is 80% efficient irrespective of the static height of the system. It is the ideal solution for large installations or high installations where standard

diaphragm expansion equipment is limited.
