## Summary description

Reflex 100 L diaphragm expansion vessel, blue finish, model 7306600. Designed to accommodate thermal expansion in closed heating and hot-water systems, this vessel features a diaphragm separating fluid and gas chambers to maintain system pressure and prevent water hammer. Suitable for residential and light commercial heating installations requiring a 100-litre expansion capacity.

## Long description

Reflex 100 L diaphragm expansion vessel in blue finish, model 7306600, is designed to manage thermal expansion in closed heating and domestic hot-water systems. The vessel separates the system fluid from a pre-charged gas chamber using a durable diaphragm, allowing the system to absorb volume changes, maintain stable pressure and reduce hydraulic shocks. With a nominal capacity of 100 litres, it is intended for residential and light commercial heating installations that require a medium-sized expansion buffer.
Advantages
The diaphragm design ensures reliable separation between liquid and gas, minimising corrosion and gas absorption into the system. A factory pre-charge and robust construction provide consistent pressure control and extended service life under normal operating conditions. The blue finish offers standard visual identification for system components and the 100-litre capacity balances compact footprint with adequate expansion reserve for typical heating circuits.
Suitable for
Closed central heating systems in single-family homes
Domestic hot-water systems with moderate expansion volumes
Light commercial heating circuits with similar hydraulic requirements
Retrofit projects where a 100-litre expansion capacity is required
Key specifications
Nominal volume: 100 litres
Diaphragm separator between liquid and gas chambers
Pre-charged gas chamber for pressure maintenance
Blue external finish for component identification
Designed for closed heating and hot-water systems
How to use
Install the expansion vessel on the return line or at the designated connection point of the heating system following the system designer's recommendations and local regulations. Ensure the vessel is mounted in a stable position and connected with appropriate fittings and isolation valves. Verify and, if necessary, adjust the pre-charge of the gas chamber to match the static pressure of the installation before filling the system. After installation, perform a leak test and monitor system pressure during initial heat-up to confirm correct operation.
Usage recommendations
Check the vessel pre-charge periodically and after any major system maintenance; maintain the recommended pre-charge to ensure proper pressure control. Use corrosion-inhibiting additives suitable for the system if required, and follow local codes and the manufacturer's installation instructions for safety and compliance.
