Description
(25bar) CWU 36 diaphragm vessel by IBO ITALY – high-pressure expansion vessel for domestic hot water
The (25bar) CWU 36 diaphragm vessel by IBO ITALY is a 36 L expansion vessel designed for domestic hot water systems operating at elevated pressure. It absorbs the thermal expansion of water and stabilizes system pressure, limiting fluctuations. The design is rated for pressure up to 25 bar (the limit), and it contains a replaceable diaphragm designed for contact with domestic water.
Who it’s for
- High-pressure system installers – the design, rated for pressure up to 25 bar, and the 3/4" connection allow the vessel to be adapted to systems operating at elevated pressure.
- High-pressure domestic hot water systems – the vessel absorbs the increase in hot water volume in systems operating at elevated pressure.
- Technical facilities and systems – the replaceable diaphragm, designed for contact with domestic water, serves demanding domestic hot water and hydrophore systems.
- Technical service – the replaceable diaphragm allows the vessel to be restored to working order without replacing the entire unit.
Applications
The (25bar) CWU 36 diaphragm vessel by IBO ITALY absorbs the thermal expansion of water in domestic hot water systems, maintaining stable pressure and limiting fluctuations while the water is heated and drawn.
It is used in domestic hot water and hydrophore systems operating at elevated pressure. The (25bar) CWU 36 diaphragm vessel by IBO ITALY is installed vertically, and the system operating pressure should be appropriately below the design limit.
Features of the IBO ITALY 36 L DHW diaphragm vessel (25 bar) - description and technical specifications
The vessel body is made of steel coated with a protective exterior paint to improve corrosion resistance. A replaceable diaphragm suitable 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 vessel body.
The vessel is designed for pressures up to 25 bar, considered the limit - the system operating pressure and safety valve setting should both be suitably 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 36 L DHW diaphragm vessel (25 bar)
What is the IBO ITALY 36 L DHW diaphragm vessel (25 bar) used for?
The IBO ITALY 36 L DHW diaphragm vessel (25 bar) accommodates the thermal expansion of water in the domestic hot water system and stabilizes its pressure. It is designed for systems operating at elevated pressures, with a construction rated for pressures up to 25 bar.
What is the difference between the (25 bar) version and the standard IBO ITALY DHW 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 pressures. The standard IBO ITALY DHW vessel operates at pressures up to 10 bar.
What does the 25 bar pressure rating 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 both be suitably lower than this value.
How do I install the IBO ITALY 36 L DHW diaphragm vessel (25 bar)?
Install the vessel vertically, using the 3/4" connection, in the domestic hot water system. We recommend fitting an isolation valve so the vessel can be serviced without draining the entire system, and adjusting the pre-charge pressure to suit the installation before start-up.
Where can I buy the IBO ITALY 36 L DHW diaphragm vessel (25 bar)?
The manufacturer does not sell directly. The IBO ITALY 36 L DHW vessel (25 bar) with diaphragm is available from retail partners, plumbing wholesalers and authorized online distributors.
What is the warranty on the IBO ITALY 36 L DHW vessel (25 bar) with diaphragm?
The IBO ITALY 36 L DHW vessel (25 bar) with diaphragm comes with a 36-month (3-year) manufacturer's warranty. Dambat provides warranty and post-warranty service.
