Expansion Vessels | Membrane Pressure Vessels

Membrane pressure expansion-vessels serve as a pressurised water reservoir for cold and warm water installations and are suitable for temperatures up to 99°C.
Required for pressurised booster-sets including water supply from wells and rainwater harvesting systems, membrane pressure vessels act as a buffer to minimise water-hammering within the pipe network and reduce pump switching cycles.
We keep stock of Zilmet Ultra-Pro pressure expansion vessels (horizontal & vertical) in the sizes 50 litres and 100 litres.
Larger vessels are available on request!
