## Summary description

Reflex N-140 expansion vessel for central heating systems, 1" connection, rated to 6 bar, grey finish. Designed to absorb pressure fluctuations and compensate thermal expansion in closed heating circuits. Suitable for residential and light commercial boilers and heating installations that require a 1" vessel with 6 bar maximum operating pressure.

## Long description

Reflex N-140 expansion vessel for central heating, with a 1" connection and maximum operating pressure of 6 bar, is engineered to compensate for thermal expansion and absorb pressure fluctuations in closed heating circuits. The grey-bodied vessel integrates into residential and light commercial boiler systems where a compact, reliable pressure-equalizing component is required. It supports stable system pressure and reduces stress on valves, pumps and piping by providing a sealed gas cushion that accepts expanded water volume as temperature rises.
Advantages
The Reflex N-140 vessel offers a robust steel construction with vessel sizing appropriate for small to medium heating circuits. Its 1" connection simplifies installation in systems designed for that thread size, and the 6 bar rating provides a safety margin suitable for many residential and light commercial setups. The grey finish helps resist visible soiling and integrates visually with typical plantroom equipment. Designed to minimize maintenance, the bladder-type separation between gas and liquid preserves precharge and performance over time when installed and serviced per manufacturer guidance.
Suitable for
 Residential central heating systems with closed-loop circuits
 Light commercial boiler installations
 Boiler replacement or retrofitting where a 1" expansion vessel is required
 Systems requiring a maximum operating pressure up to 6 bar
Key specifications
 Connection size: 1 inch
 Maximum operating pressure: 6 bar
 Function: absorption of thermal expansion and pressure fluctuations in closed heating circuits
 Body finish: grey
 Typical installation position: vertical or as recommended by system designer
How to use
Install the expansion vessel in the heating circuit according to local regulations and the system designer's layout, ensuring the 1" connection is compatible with existing piping or adapters. Precharge the vessel to the correct air pressure (usually matched to the system's static pressure) before commissioning, and secure the vessel to avoid mechanical strain on the connection. After installation, pressurize and fill the system slowly, vent air from high points and verify that the vessel accepts expansion without excessive cycling of the boiler or pressure relief devices.
Usage recommendations
Check the vessel precharge periodically and inspect for visible corrosion or damage. Confirm compatibility with system water treatment practices and observed system pressures; replace or service the vessel if the bladder shows signs of failure or if the vessel no longer maintains pressure balance. Follow local rules for pressure equipment handling and the installation instructions provided with the vessel.
