Zilmet Hydro Pro 50L Potable Expansion Vessel

The Zilmet Hydro Pro 50L Potable Expansion Vessel is designed for domestic hot water and potable water systems that require additional expansion capacity. Its 50 litre capacity helps accommodate thermal expansion and maintain stable system pressure in larger water heating and pressurised water installations.

The fixed butyl membrane is designed to minimise water stagnation, while the MIG-welded carbon steel shell and durable epoxy powder-coated finish provide a robust solution for hot water expansion control. Its floor-standing format offers stable installation for larger domestic and commercial hot water systems.

Please note: Vessel shape may differ slightly from the product image.
