## Summary description

Reflex DE expansion vessel, model 7306005, with 50-litre capacity and 10 bar maximum working pressure designed for domestic hot water systems. The diaphragm-type vessel compensates for thermal expansion in closed hot water installations, helps maintain system pressure stability and protects components from overpressure. Suitable for residential and light commercial hot water applications.

## Long description

The Reflex DE 50L expansion vessel for domestic hot water systems is a diaphragm-type pressure vessel designed to absorb volume changes caused by thermal expansion. With a 50-litre nominal capacity and a maximum working pressure of 10 bar, this vessel helps stabilise system pressure in closed hot water installations and protects pumps, valves and piping from pressure fluctuations. The Reflex design is intended for residential and light commercial applications where reliable pressure management and corrosion protection are required.
Advantages
This expansion vessel uses a flexible diaphragm to separate the water and pre-charged gas chamber, preventing direct contact and reducing corrosion risk. Its 50-litre capacity provides a balance between compact installation footprint and expansion buffering, while the 10 bar rating allows compatibility with typical domestic hot water systems. The vessel is constructed for long service life under normal operating conditions and contributes to the stable operation of circulation pumps and safety devices by limiting pressure peaks.
Suitable for
 Closed domestic hot water systems in single-family homes
 Light commercial hot water installations with moderate duty cycles
 Systems requiring protection of pumps, valves and fittings from thermal expansion
 Retrofit projects where a compact 50 L expansion vessel is needed
Key specifications
 Nominal volume: 50 litres
 Maximum working pressure: 10 bar
 Diaphragm-sealed vessel design to separate water and gas
 Intended application: closed domestic hot water systems
 Compact form factor suitable for wall-mounted or floor-mounted installations depending on space
How to use
Install the expansion vessel in the hot water circuit at a location recommended by the system designer or installer, typically near the primary circulation pump or close to the safety group. Ensure the vessel is mounted securely and positioned according to the manufacturer’s instructions for orientation and support. Check and set the pre-charge pressure of the gas side to match the static system pressure before introducing water. After installation, pressurise the system gradually and inspect for leaks. Periodic checks of pre-charge pressure and vessel integrity are recommended as part of routine system maintenance.
Usage recommendations
Verify compatibility with the system maximum pressure and temperature specifications and confirm correct pre-charge pressure before commissioning. Consider routine visual inspection and pressure checks at regular maintenance intervals to ensure continued performance and to avoid system overpressure or pump cavitation.
