Zilmet Hydro Pro 105L Potable Expansion Vessel

The Zilmet Hydro Pro 105L Potable Expansion Vessel provides increased expansion capacity for larger domestic hot water, potable water and pressurised water systems. Its 105 litre capacity helps accommodate thermal expansion as water is heated, supporting more stable system pressure and reducing unnecessary strain on associated components.

The Hydro Pro uses a fixed butyl membrane designed to minimise areas where water can stagnate. Its MIG-welded carbon steel shell and hard-wearing epoxy powder-coated finish provide a durable solution for larger water heating and plumbing installations. The floor-standing design is suited to compatible water heaters, boilers and pump systems.

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