Zilmet Hydro Pro 200L Potable Expansion Vessel

The Zilmet Hydro Pro 200L Potable Expansion Vessel is designed for larger-capacity domestic hot water, potable water and pressurised water systems. Its 200 litre capacity provides substantial expansion volume to accommodate changes in water volume as temperature increases, helping manage system pressure.

The Hydro Pro features a fixed butyl membrane designed to minimise areas where water can stagnate, together with a MIG-welded carbon steel shell and durable epoxy powder-coated exterior. Its floor-standing configuration makes it suitable for larger commercial and domestic water heating installations.

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