Expansion Tank Cimm ERE CE 150 L

Product detailed description

Expansion tanks are essential components in closed heating systems where thermal expansion of water must be accommodated. They are commonly installed in residential, commercial and industrial buildings with hydronic heating systems. The Cimm ERE CE 150 L is suitable for systems with moderate expansion requirements, such as those with radiators, underfloor heating or heat pumps. It ensures pressure stability and prevents damage to system components from overpressure. Installers must ensure correct sizing and positioning to maintain system efficiency and safety.

During installation, the tank is typically mounted on a wall near the boiler or pump unit. It is connected to the system via a dedicated pipe, and the pre-charge pressure must be adjusted to match the system's operating pressure. The tank's location should allow for easy access for maintenance and inspection. It is important to avoid placing the tank in areas with extreme temperatures or direct sunlight, as this can affect its performance and longevity.

The 150 L capacity of the Cimm ERE CE 150 L makes it suitable for systems with moderate expansion volumes. The operating pressure of 1.5 bar ensures compatibility with standard heating systems, while the maximum overpressure of 6.0 bar provides a safety margin. The tank's working temperature range of -10 to +100 °C allows it to function in a variety of climates and system conditions. These parameters are critical for proper sizing and selection to ensure the tank can handle the system's thermal expansion without exceeding its pressure limits.

Installation and connection

The Cimm ERE CE 150 L is connected using a M 3/4 inch G thread, which is a standard connection for many European heating systems. Installers should ensure the connection is clean and free of debris before tightening the fittings. A wrench should be used to secure the connection without over-tightening, which could damage the threads. It is important to verify that the tank is installed in a vertical position to ensure proper internal diaphragm function. Common installation errors include incorrect orientation, improper pre-charge pressure settings, and failure to isolate the tank during system pressure checks. Always refer to the manufacturer's instructions for specific installation guidelines.

Compatibility and accessories

The Cimm ERE CE 150 L is compatible with most standard heating systems that use water as the heat transfer medium. It is typically used in conjunction with a pressure relief valve and a pressure gauge to monitor system pressure. Additional accessories such as mounting brackets or insulation may be required depending on the installation environment. While no specific related products are listed, installers should ensure that all system components are compatible with the tank's operating parameters to avoid performance issues or premature failure.

Technical background for designers

The Cimm ERE CE 150 L operates on the principle of a closed expansion tank with a flexible diaphragm that separates the air and water compartments. As the system heats up, the water expands and compresses the air in the tank, maintaining a stable pressure. The tank is constructed from durable materials that can withstand the operating conditions specified in the technical parameters. The white colour indicates a standard coating that provides protection against corrosion. The tank's integration into the system depends on the system's expansion volume and pressure requirements. Factors that affect the tank's service life and efficiency include the quality of the installation, the system's operating conditions, and the frequency of maintenance checks.

Service and operation

Regular inspection of the Cimm ERE CE 150 L is recommended to ensure it continues to function correctly. This includes checking the pre-charge pressure and verifying that the tank is not overfilled or damaged. If the tank shows signs of leakage or excessive pressure fluctuations, it should be replaced immediately. No specific service intervals are provided in the technical data, so it is advisable to follow the manufacturer's recommendations for maintenance. During operation, the tank should be monitored for any changes in performance that could indicate a need for servicing or replacement.

Frequently asked questions

Can the Cimm ERE CE 150 L be connected to a system with a pressure relief valve?
Yes, the tank can be connected to a system with a pressure relief valve. The valve should be sized and set according to the system's maximum pressure to ensure safe operation.

Is the Cimm ERE CE 150 L suitable for use in a system with a heat pump?
Yes, the tank is suitable for use in systems with heat pumps, provided the system's expansion volume and pressure requirements match the tank's specifications.

Can the Cimm ERE CE 150 L be installed in a horizontal position?
No, the tank must be installed in a vertical position to ensure the internal diaphragm functions correctly and to prevent uneven pressure distribution.

What should be done if the pre-charge pressure is incorrect?
If the pre-charge pressure is incorrect, it should be adjusted using a pressure gauge and a suitable pump or valve. The pressure should be set to match the system's operating pressure as specified in the manufacturer's instructions.
