Description
IBO ITALY SOLAR 24 diaphragm expansion vessel – expansion vessel for solar installations
The IBO ITALY SOLAR 24 diaphragm expansion vessel has a capacity of 24 L and is designed for solar collector installations. It accommodates the thermal expansion of the solar fluid and stabilizes circuit pressure, reducing fluctuations during significant temperature changes. It contains an EPDM diaphragm that withstands the high temperatures typical of solar systems.
Who it's for
- Solar installation professionals – the 3/4" connection and high-temperature-resistant EPDM diaphragm make installation in a solar collector circuit easier.
- Solar collector installations – the vessel accommodates the increase in solar fluid volume as it heats up, maintaining stable pressure in the circuit.
- Systems operating at high temperatures – an operating range of up to 100°C (briefly up to 130°C) meets the requirements of solar installations.
- Technical servicing – a pre-charge pressure of 2.5 bar and a simple design make commissioning and periodic inspections easier.
Applications
The IBO ITALY SOLAR 24 diaphragm expansion vessel accommodates the thermal expansion of the solar fluid in the solar collector circuit, maintaining stable pressure and reducing fluctuations as the system heats up and cools down.
It is used in solar installations operating with solar fluid, usually a glycol solution. The IBO ITALY SOLAR 24 diaphragm expansion vessel can be installed vertically or horizontally, on the suction side of the circulation pump.
Features of the IBO ITALY SOLAR 24 diaphragm expansion vessel – description and technical data
The vessel body is made of steel coated with a protective exterior paint that increases corrosion resistance. Inside the steel shell is an EPDM rubber diaphragm, resistant to high temperatures and stretching, allowing it to withstand the operating conditions typical of solar circuits. The diaphragm separates the solar fluid from the compressed gas cushion, limiting its contact with the inside of the vessel.
The vessel is supplied with a factory pre-charge pressure of 2.5 bar ±10%, which can be adjusted to suit the specific system. It is compatible with solar circuits with a maximum operating pressure of 10 bar and a temperature range from −10 to 100°C, with short-term operation up to 130°C.

Frequently asked questions (FAQ) – IBO ITALY SOLAR 24 diaphragm expansion vessel
What is the IBO ITALY SOLAR 24 diaphragm expansion vessel used for?
The IBO ITALY SOLAR 24 diaphragm expansion vessel accommodates the thermal expansion of solar fluid in solar collector circuits and stabilizes system pressure. This helps limit pressure fluctuations caused by major temperature changes in the solar system.
How does the IBO ITALY SOLAR vessel differ from the CH version?
The SOLAR vessel is designed for solar collector circuits, uses solar fluid (a glycol solution) and has a high-temperature-resistant EPDM diaphragm, with a pre-charge pressure of 2.5 bar. The IBO ITALY CH version is designed for central heating systems and has a pre-charge pressure of 1.5 bar.
What is the vessel’s pre-charge pressure, and can it be changed?
The factory pre-charge pressure is 2.5 bar ±10%. It can be adjusted to suit the height of the fluid column and the solar system parameters by adding or releasing gas through the valve on the vessel connection, with the system isolated and depressurized.
How do I install the IBO ITALY SOLAR 24 diaphragm expansion vessel?
The vessel can be installed vertically or horizontally, with a 3/4" connection, in a solar circuit. It is recommended to install it on the suction side of the circulation pump and set the pre-charge pressure to match the system parameters before commissioning.
Where can I buy the IBO ITALY SOLAR 24 diaphragm expansion vessel?
The manufacturer does not sell directly. The SOLAR 24 IBO ITALY diaphragm vessel is available from retail partners, plumbing and heating wholesalers, and authorized online distributors.
What warranty does the SOLAR 24 IBO ITALY diaphragm vessel have?
The SOLAR 24 IBO ITALY diaphragm vessel comes with a 36-month (3-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
