Vaso de expansión CIMM CP387/8 tipo 4 para calderas Baxi

This expansion vessel, listed under catalogue article 294.116.004-2 and manufacturer code 294.116.004, is designed for use with Baxi boilers. It falls under the expansion vessels category. Parts of this type absorb the volume change of water as it heats, keeping system pressure within limits. They are selected by vessel volume and pre-charge pressure, connection thread, membrane material, and suitability for potable water. Typical failures include a lost pre-charge or a ruptured membrane, which cause system pressure to swing and the safety valve to vent. When replacing such a vessel, confirm that the new unit matches the required volume, connection size, and pre-charge setting for the system. Ensure the membrane material is compatible with the system water, particularly if the water is potable or treated. No further specifics about this particular article beyond its designation and intended use for Baxi boilers are available in the source data. Selection must be made based on system parameters and the existing vessel’s specifications.
