SOLAR IBO ITALY 36 diaphragm expansion vessel – expansion vessel for solar installations
The SOLAR IBO ITALY 36 diaphragm expansion vessel is a 36 l expansion vessel designed for solar collector installations. It accommodates the thermal expansion of the solar fluid and stabilizes pressure in the circuit, reducing fluctuations during large temperature changes. It features 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 it easy to install in a solar collector circuit.
-
Solar collector installations – the expansion vessel accommodates the increase in the volume of the solar fluid as it heats up, maintaining stable pressure in the circuit.
-
Systems operating at high temperatures – operating range up to 100°C (up to 130°C for short periods) suits solar installations.
-
Technical service – a pre-charge pressure of 2.5 bar and a simple design make commissioning and periodic inspections easier.
Application
The IBO ITALY 36 SOLAR expansion vessel accommodates the thermal expansion of solar fluid in solar collector circuits, maintaining stable pressure and limiting fluctuations as the system heats up and cools down.
It is used in solar systems operating with solar fluid, usually a glycol solution. The IBO ITALY 36 SOLAR expansion vessel can be installed vertically or horizontally, on the suction side of the circulation pump.
Features of the IBO ITALY 36 SOLAR vessel – description and technical specifications
The vessel body is made of steel coated with an external protective finish 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 installation. It is compatible with solar circuits with a maximum operating pressure of 10 bar and a temperature range from −10 to 100°C, briefly up to 130°C.

Frequently asked questions (FAQ) – IBO ITALY 36 SOLAR expansion vessel
What is the IBO ITALY 36 SOLAR expansion vessel used for?
The IBO ITALY 36 SOLAR vessel accommodates the thermal expansion of solar fluid in solar collector circuits and stabilizes system pressure. This helps limit pressure fluctuations caused by large temperature changes in the solar system.
How does the SOLAR vessel differ from the IBO ITALY CO version?
The SOLAR vessel is designed for solar collector circuits. It operates with 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 CO 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 the height of the fluid column and the specifications of the solar system by adding or releasing gas through the valve on the vessel connection, with the system isolated and depressurized.
How do I install the SOLAR IBO ITALY 36 diaphragm vessel?
The vessel can be installed vertically or horizontally, with a 3/4" connection, in the solar circuit. It is recommended to install it on the suction side of the circulation pump and adjust the pre-charge pressure to the system specifications before commissioning.
Where can I buy the SOLAR IBO ITALY 36 diaphragm vessel?
The manufacturer does not sell directly. The SOLAR IBO ITALY 36 vessel is available from sales partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the SOLAR IBO ITALY 36 vessel?
The SOLAR IBO ITALY 36 diaphragm vessel comes with a 36-month (3-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
