Zilmet Hydro Pro 600L Potable Expansion Vessel

The Zilmet Hydro Pro 600L Potable Expansion Vessel is made for large domestic hot water, potable water and pressurised water systems that need substantial expansion capacity. Its 600 litre volume helps accommodate thermal expansion as water temperature rises, supporting stable pressure across high-capacity installations.

This floor-standing expansion vessel pairs a robust MIG-welded carbon steel shell with a durable epoxy powder-coated finish. The fixed butyl membrane is designed to minimise stagnant water areas, making it a practical solution for commercial water heating, boilers, pump systems and boosted water systems.

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