## Summary description

Diaphragm expansion vessel CIMM ERE with 50 L capacity designed for closed central heating (CO) systems. Features working pressure range of 1.5–6 bar and operating temperature from -10 to +100°C. Provides hydraulic compensation of thermal expansion, protects system components and reduces pressure fluctuations. Suitable for residential and light commercial heating installations.

## Long description

The CIMM ERE 50 L diaphragm expansion vessel is designed for closed central heating systems to compensate for thermal expansion of the heating medium. With a nominal capacity of 50 litres and an operating temperature range from -10 to +100°C, this expansion vessel stabilizes system pressure, reduces pressure fluctuations and protects pumps, valves and boiler components in residential and light commercial installations.
Advantages
This expansion vessel uses a durable diaphragm to separate the air cushion from the heating fluid, ensuring reliable hydraulic compensation and minimizing the risk of waterlogging. The specified working pressure range of 1.5–6 bar accommodates typical central heating circuits, while the compact vertical design simplifies installation in plant rooms or service cupboards. Materials and construction are selected to provide corrosion resistance and long service life under normal operating conditions.
Suitable for
Closed central heating systems in single-family homes
Small multi-family dwellings and light commercial heating circuits
Systems requiring hydraulic compensation for temperature-related volume changes
Key specifications
Nominal capacity: 50 L
Working pressure range: 1.5–6 bar
Operating temperature range: -10…+100°C
Diaphragm-type vessel with separated air cushion
Vertical compact body suitable for indoor installation
How to use
Install the expansion vessel on the return line or at the hydraulic connection point recommended by the heating system designer, following local regulations and manufacturer's installation instructions. Pre-charge the air side to the required static pressure before commissioning and verify system pressure when cold. Periodically check the pre-charge and inspect connections for leaks; perform maintenance or replacement of the diaphragm if operational signs indicate loss of air cushion or waterlogging.
Usage recommendations
Verify compatibility with system volume and maximum allowable pressure before selecting the vessel. Ensure correct mounting orientation and accessible service isolation valves. For optimal performance, match the pre-charge pressure to the system cold pressure and schedule periodic inspections to confirm integrity and pre-charge levels.
