## Long description

The Comap Contraflex 50L expansion vessel is a high-quality component engineered for closed-loop central heating systems. Its primary function is to absorb the thermal expansion of water as it heats up, preventing dangerous pressure spikes and maintaining consistent system stability. Constructed from robust red steel, this vessel provides a reliable solution for managing pressure fluctuations in both residential and commercial heating setups.
Advantages
This expansion vessel offers exceptional durability due to its high-grade steel construction, which is designed to withstand the rigors of continuous operation in heating systems. The 50-liter capacity is ideal for medium-sized installations, ensuring that the system remains balanced even during significant temperature changes. Its factory-set pre-charge of 1.5 bar allows for quick and easy installation, while the standard 3/4 inch connection ensures compatibility with most common heating pipework configurations.
Suitable for
Closed-loop central heating systems
Residential heating installations

How to use
Installation should be performed by a qualified heating engineer to ensure system safety and compliance with local regulations. The vessel is typically connected to the return pipe of the heating circuit. Before installation, verify that the system pressure is fully depressurized. Ensure the vessel is mounted in a vertical position to allow for proper operation of the internal diaphragm. After connection, check the system for leaks and verify that the pre-charge pressure matches the specific requirements of your heating system design.
What to consider before purchase
Verify that the 50-liter capacity is sufficient for the total water volume of your heating system.
Ensure the 3 bar maximum pressure rating meets your system requirements.
Check available space for mounting the vessel, considering its physical dimensions.
Confirm that the 3/4 inch connection is compatible with your existing piping.
Usage recommendations
Regular maintenance checks are recommended to ensure the pre-charge pressure remains at the required level. Inspect the vessel annually for signs of corrosion or damage to the diaphragm to maintain optimal system performance.
