The Cimm 2-Litre Potable Expansion Vessel is a compact, commercial-grade pressure vessel designed for domestic hot and cold sanitary water circuits, water pressurising systems, and small-scale heating or cooling loops. Commonly utilised as a water hammer arrestor or small expansion buffer, its primary function is to absorb sudden pressure spikes and thermal expansion within tight plumbing layouts. This targeted protection prevents safety valves from weeping and minimises physical strain on pipework joints, taps, and domestic appliances.
- Interchangeable membrane pressure tank for hot and cold sanitary water circuits, pressurising systems, heating systems and refrigeration circuits.
- Epoxy powder exterior painting to guarantee a high level of protection against oxidation and a fine aesthetic final quality
