250 Litre Membrane Expansion Vessel CMF 1"

The Ibaiondo CMF 250-litre membrane expansion vessel is a key component in closed heating and cooling systems, designed to absorb water expansion when heated, thus preventing overpressure that could damage the installations. This model is manufactured from high-quality steel and finished with a red paint coating, providing excellent corrosion resistance and ensuring a long service life.

Robust and efficient design

This expansion vessel features a non-replaceable membrane in accordance with EN 13831 standards, specific for non-potable heating and cooling systems. With a capacity of 250 litres and a maximum pressure of 6 bar, it is perfect for large-scale installations where efficient water pressure control is required. The system helps maintain appropriate pressure at all times, ensuring the safety and proper functioning of the climate control system.

Additionally, its 1” water connection guarantees easy and quick installation. It includes an inflation valve that allows for pre-charge pressure adjustment, which is factory set at 1.5 bar but can be modified according to system specifications.

High resistance and regulatory compliance

The Ibaiondo CMF 250-litre expansion vessel meets the requirements of the 2014/68/EU Directive, ensuring it has been manufactured to the highest quality and safety standards. It has been pressure tested up to 9 bar, exceeding its service pressure of 6 bar, making it a robust and reliable piece of equipment suitable for demanding conditions.

This model is also prepared to withstand a wide range of temperatures, with a maximum service temperature of 100°C and a minimum of -10°C, making it suitable for both heating and cooling systems.
