Genuine Cimm ERE 12 12 Litre Expansion Vessel
Genuine Cimm ERE 12 12 litre expansion vessel for sealed central heating and chilled water circuits, with a 3/4" BSP male connection and a 1.5 bar factory pre-charge.
What it does
Water expands as it is heated, and in a sealed heating circuit that expansion has nowhere to go, so pressure rises until the safety valve lifts. The vessel takes up the extra volume against a pre-charged air cushion and holds system pressure steady. The ERE uses a fixed rubber diaphragm rather than an interchangeable bag, designed to hold its air pre-charge at the higher temperatures a heating circuit sees. A vessel that has lost its charge is the usual reason a boiler keeps losing pressure or dumping through the relief valve.
Where it fits
Sealed (closed) central heating systems, chilled water and refrigeration circuits; absorbs the expansion of the system water so pressure stays within limits; 12 litre, 3/4" BSP male connection, 1.5 bar pre-charge, 4.0 bar maximum.
