Zilmet Hydro Pro 150L Potable Expansion Vessel

The Zilmet Hydro Pro 150L Potable Expansion Vessel is designed for larger domestic hot water, potable water and pressurised water systems. Its 150 litre capacity provides substantial expansion volume to accommodate changes in water volume as it is heated, helping manage system pressure.

A fixed butyl membrane helps minimise areas where water can stagnate, while the MIG-welded carbon steel shell provides robust vessel construction. The durable epoxy powder-coated finish makes this floor-standing expansion vessel suitable for larger plumbing and water heating installations.

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