The Inta 2 Litre Expansion Vessel is a robust commercial-grade hydraulic component specifically designed to absorb volumetric expansion in undersink heating systems, pumps and booster sets. Constructed with a heavy-duty MIG-welded carbon steel shell and finished with a hard-wearing blue epoxy powder coating, this wall-mounted unit offers high resistance to external corrosion in damp undersink environments. The vessel features a fixed membrane secured at both ends, which explicitly prevents any contact between the internal steel shell and the membrane to maintain system water purity.

Measuring 196mm in height and 142mm in diameter, this compact 1.7kg unit seamlessly integrates into tight plumbing cavities while withstanding an impressive maximum operating pressure of 10 bar. It is engineered to operate reliably at temperatures up to 70 degrees Celsius and is fully certified according to PED 97/23/CE standards. Equipped with a stainless steel threaded connection and galvanised steel flanges, the vessel ensures a secure and leak-free integration into existing potable water networks. Every single unit undergoes rigorous 100% factory testing to guarantee structural integrity and operational safety for trade installers.
