This product is the Zilmet Hydro-Pro 12-Litre Wall-Mounted Potable, Fixed Membrane Vessel Z1-300012WH. It is part of the Hydro-Pro range from Inta manufactuer.

Operation of Hydro-Pro Zilmet range:

The HYDRO-PRO range of Expansion Vessels is specifically designed for Unvented Potable Systems to deal with increased water volume resulting from heat expansion.

The purpose of these vessels is to accommodate the increased liquid volume which occurs during system heating in an Unvented Circuit. A pressurised membrane allows ingress/egress of the liquid only during periods of heating / cooling.

The correct size of vessel must be considered prior to installation and installed by appropriately trained engineers.

Installation Siting for Hydro-Pro Zilmet range:

The Expansion Vessel may be fitted to a very wide range of systems, different sources of heat are applied to Unvented Hot Water Systems, and as long as the temperature is controlled within normal limits, the HYDRO-PRO will be compatible in it’s application.

Installations where the heat source is augmented by Solid Fuel, Solar Thermal or other heat sources with potentially uncontrolled input temperatures are not compatible with these vessels and an alternative model should be specified.

The physical siting of the vessel should always be in accordance with the Cylinder manufacturers instructions as a variety of acceptable siting options is available.

Main product features:

• Suitable for potable water, pumps and booster sets
• Galvanised steel flanges
• Stainless steel threaded connection
• MIG welded carbon steel shell construction
• Fixed membrane at both ends of the vessel prevents contact between the vessel and membrane
