Description
IBO ITALY 80 L DHW diaphragm vessel (25 bar) – high-pressure expansion vessel for domestic hot water
The IBO ITALY 80 L DHW diaphragm vessel (25 bar) is an 80 L expansion vessel designed for domestic hot water systems operating at elevated pressure. It accommodates the thermal expansion of water and stabilizes system pressure, limiting fluctuations. It is designed for pressures up to 25 bar (limit value) and contains a replaceable diaphragm suitable for contact with potable water.
Who it's for
- High-pressure system installers – the design pressure of up to 25 bar and 1" connection make it possible to adapt the vessel to high-pressure systems.
- High-pressure domestic hot water systems – the vessel accommodates the increase in hot water volume in systems operating at elevated pressure.
- Technical facilities and systems – the replaceable diaphragm, designed for contact with potable water, supports demanding DHW and pressurized water systems.
- Technical maintenance – the replaceable diaphragm lets you restore the vessel to working order without replacing the entire unit.
Applications
The IBO ITALY 80 L DHW diaphragm vessel (25 bar) accommodates the thermal expansion of water in domestic hot water systems, maintaining stable pressure and limiting fluctuations during water heating and draw-off.
It is used in domestic hot water and pressurized water systems operating at elevated pressure. The IBO ITALY 80 L DHW diaphragm vessel (25 bar) is installed vertically, and the system operating pressure should be sufficiently below the design limit.
Features of the IBO ITALY 80 L DHW diaphragm vessel (25 bar) – description and technical data
The vessel body is made of steel coated with a protective exterior paint to increase corrosion resistance. A replaceable diaphragm designed for contact with potable water and resistant to elevated hot water temperatures is fitted inside the steel shell. The diaphragm separates the water from the compressed gas cushion, limiting its contact with the inside of the body.
The vessel is designed for pressures up to 25 bar, treated as the limit value—the system operating pressure and safety valve setting should be correspondingly lower. The vessel is suitable for domestic hot water systems operating at temperatures from −10 to 100°C (up to 130°C for short periods).

Frequently asked questions (FAQ) – IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm
What is the IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm used for?
The IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm absorbs the thermal expansion of water in the domestic hot water system and stabilizes its pressure. It is intended for systems operating at elevated pressure and is designed for pressures up to 25 bar.
How does the (25 bar) version differ from the standard IBO ITALY CWU expansion vessel?
The (25 bar) version is designed for a higher pressure limit (up to 25 bar) and intended for domestic hot water systems operating at elevated pressure. The standard IBO ITALY CWU expansion vessel operates at pressures up to 10 bar.
What does a pressure of 25 bar mean for this vessel?
25 bar is the design limit – the maximum permissible short-term load, not the operating pressure. The system operating pressure and safety valve setting should be appropriately lower than this value.
How do I install the IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm?
Install the vessel vertically, using the 1" connection, in the domestic hot water system. A shut-off valve is recommended to allow servicing without draining the entire system. Adjust the pre-charge pressure to suit the system conditions before commissioning.
Where can I buy the IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm?
The manufacturer does not sell directly. The IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm is available from retail partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm?
The IBO ITALY CWU 80 expansion vessel (25 bar) with diaphragm comes with a 36-month (3-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
