Zilmet Cal-Pro 200Ltr Heating Vessel

The CAL-PRO range of Expansion Vessels is specifically designed for domestic and commercial unvented central heating systems. The purpose of these vessels is to accommodate the increased liquid volume which occurs during system heating in an Unvented Circuit. A pressurised membrane allows ingress/egress of the liquid only during periods of heating / cooling. The correct size of vessel must be considered prior to installation and installed by appropriately trained engineers.
