## Summary description

Reflex N 250 L is a diaphragm expansion vessel designed for central heating (C.O.) systems. The vessel provides 250 liters of hydraulic capacity to absorb pressure fluctuations and thermal expansion in closed heating installations. It features a diaphragm separation of air and water, connection fittings for integration into heating circuits, and is intended for residential and commercial boiler systems to stabilize pressure and protect components.

## Long description

Reflex N 250 L is a diaphragm expansion vessel specifically engineered for closed central heating (C.O.) systems. With a hydraulic capacity of 250 liters, the vessel accommodates thermal expansion and pressure fluctuations that occur during boiler operation. The internal diaphragm separates the water circuit from the pre-charged air cushion, helping to maintain stable system pressure, reduce cycling of pumps and burners, and protect valves, heat exchangers and pipework from pressure-related stress.
Advantages
The diaphragm design ensures reliable separation of water and air, preventing air absorption into the heating circuit and reducing the need for frequent venting. A 250 L capacity covers larger domestic and small commercial installations, enabling smoother pressure control and fewer intervention events. The vessel’s fittings are arranged to facilitate integration into existing heating circuits and to provide a durable interface with standard system components.
Suitable for
 Residential central heating systems with significant water volume and thermal expansion
 Small commercial boiler systems and multi-zone installations
 Replacement or retrofit in systems requiring increased hydraulic capacity
Key specifications
 Hydraulic capacity: 250 liters
 Diaphragm-type separation between air and water
 Connection fittings for integration into closed heating circuits
 Suitable for closed (sealed) central heating installations
 Designed to reduce pressure fluctuations and thermal expansion effects
How to use
Install the expansion vessel in accordance with the heating system design and local regulations, typically on the return line or other recommended location where it can effectively absorb system expansion. Ensure the vessel is mounted securely and that connection fittings are sealed and compatible with the system piping. Check and set the pre-charge air pressure to match the static system pressure before filling the heating circuit. After installation, bleed the system to remove trapped air and verify steady operating pressure during a normal heating cycle.
Usage recommendations
Regularly inspect the vessel’s pre-charge pressure and external condition as part of scheduled system maintenance. Verify compatibility with the system’s maximum operating pressure and temperature limits and consult the system documentation or a qualified technician if adjustments or replacements are required.
