Ibaiondo CMF 300-Liter Membrane Expansion Vessel 1"

The Ibaiondo CMF 300 expansion tank with reference 04300351 is designed for use in closed heating and cooling systems. With a useful volume of 300 liters and a maximum operating pressure of 6 bar, this model is ideal for large-capacity installations that require effective absorption of thermal fluid volume variations due to temperature changes.

The Ibaiondo CMF model is manufactured in a vertical arrangement with top connection, facilitating its integration into large technical rooms and hydraulic circuits. The body is constructed of durable steel and protected with a layer of red exterior paint, ensuring a long service life against corrosion and external agents.

Its non-replaceable internal membrane is manufactured in accordance with the EN 13831 standard for non-potable applications, making it a safe and low-maintenance solution. The system is pre-charged with air at 1.5 bar from the factory (EXWORKS) and includes a filling valve for further adjustments during system commissioning.
