IBO 24l expansion vessel

Product detailed description

Expansion vessels are essential components in closed heating and cooling systems where thermal expansion of water must be accommodated. This IBO model is suitable for residential and commercial heating systems, including those with boilers, heat pumps and underfloor heating. Installers typically integrate these vessels near the boiler to manage pressure fluctuations caused by temperature changes in the system. The vessel must be correctly sized to ensure the system operates within safe pressure limits.

Proper installation requires careful consideration of static water height and pre-charge pressure. The vessel must be positioned so that the static head of water at the installation point does not exceed the pre-charge pressure marked on the vessel. This ensures the system remains balanced and avoids pressure overloads. The maximum water temperature of 99°C must also be respected to maintain component integrity and system safety.

Technical parameters

The EAN code and physical dimensions are key for logistics and space planning. The dimensions of 46 x 27 cm define the footprint and height of the vessel, which is important for fitting into standard installation spaces. These parameters are used to verify product identity and ensure compatibility with existing system layouts.

Installation and connection

Installation of the IBO 24l expansion vessel requires adherence to specific guidelines. The vessel should be mounted in a location where it is easily accessible for inspection and maintenance. It must be connected to the system using appropriate pipe fittings, ensuring a secure and leak-free connection. The pre-charge pressure of 1.5 bar must be verified before operation using a pressure gauge. A common mistake is incorrect positioning where the static water height exceeds the pre-charge pressure, which can lead to system instability. Installers should also check that the vessel is not subjected to freezing conditions, as this can damage the internal diaphragm and compromise system performance.

Compatibility and accessories

This expansion vessel is compatible with standard heating systems that operate within the specified temperature and pressure limits. It is typically used in conjunction with pressure relief valves and temperature sensors to ensure system safety. No additional accessories are required for basic operation, but installers may choose to include monitoring devices for enhanced system control.

Technical background for designers

The IBO 24l expansion vessel operates on a thermodynamic principle, using a rubber diaphragm to separate the water and gas compartments. As the water in the system heats up and expands, the diaphragm compresses the gas, allowing the vessel to absorb the increased volume. The gas is pre-charged to 1.5 bar, which helps maintain system pressure within safe limits. The diaphragm is made from a specialized rubber compound that is resistant to thermal degradation and chemical exposure. The vessel's performance is influenced by the accuracy of the pre-charge pressure, the quality of the diaphragm and the system's operating conditions. Proper integration into the system ensures efficient pressure management and prolongs the vessel's service life.

Service and operation

Regular inspection of the expansion vessel is recommended to ensure it continues to function correctly. Key checkpoints include verifying the pre-charge pressure and checking for signs of diaphragm wear or leakage. If the pressure is found to be outside the specified range, it should be adjusted using a suitable pump and pressure gauge. No specific service intervals are provided in the technical data, but any visible damage or performance issues should be addressed promptly to avoid system failure.

Frequently asked questions

Can the IBO 24l expansion vessel be used in a cooling system?
Yes, the vessel is suitable for both heating and cooling systems as long as the operating temperature and pressure limits are respected.

What happens if the pre-charge pressure is incorrect?
An incorrect pre-charge pressure can lead to pressure imbalances in the system, potentially causing overpressure or underperformance. It should be adjusted to the specified 1.5 bar before operation.

Is the diaphragm replaceable?
The diaphragm is an internal component and is not designed for field replacement. If it is damaged, the vessel should be replaced by a qualified technician.

Can this vessel be installed vertically or horizontally?
The vessel can be installed in either orientation, provided it is mounted securely and the connection points are accessible for maintenance.
