Membrane expansion vessel 250 liters CMF 1"

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

Robust and efficient design

This expansion vessel features a non-replaceable membrane in accordance with the EN 13831 standard, specific for non-potable heating and air conditioning systems. With a capacity of 250 liters 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 the appropriate pressure at all times, ensuring the safety and proper functioning of the air conditioning system.

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

High resistance and regulatory compliance

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

This model is also designed 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.
