Frequently Asked Questions (FAQ Page)
What differentiates a fixed membrane expansion vessel from a replaceable one?
A fixed-membrane vessel, such as the Ibaiondo CMF model, is considered a sealed component and does not allow for replacement of the internal rubber membrane. If the membrane fails, the entire vessel must be replaced.They are more economical for iStandard installations where periodic maintenance of the vessel is less critical.
What is the optimal temperature range for CMF installation?
This vessel is designed to operate efficiently with fluid temperatures between -10º and +100ºThis makes it compatible with the vast majority of residential and industrial heating and cooling systems.
How do I check the preload of 1.5 bar before installation?
It is essential to check the factory pre-charge pressure with an air gauge before connecting the tank to the system. If the pressure differs from 1.5 bar (the one recommended for most domestic systems), should be adjusted according to the specifications of your boiler manufacturer and the static height of the installation.
