## Summary description

Reflex N 200 L is a 200‑litre membrane expansion vessel designed for closed central heating (C.O.) systems. The tank absorbs pressure fluctuations and thermal expansion, protecting the system from overpressure and frequent pump cycling. Key features include a diaphragm/membrane separator, threaded connection for installation, and suitability for domestic or small commercial heating installations.

## Long description

Reflex N 200 L is a 200-litre membrane expansion vessel designed for closed central heating (C.O.) systems. The tank compensates for thermal expansion and absorbs pressure fluctuations created during heating and cooling cycles, helping to stabilise system pressure and reduce pump cycling. The vessel features an internal diaphragm separator and a threaded connection for straightforward installation in domestic and small commercial heating installations.
Advantages
The membrane design separates the heating medium from the preloaded air cushion, preventing corrosion and maintaining consistent performance throughout the operating range. Its 200-litre capacity provides ample buffering for medium-sized systems, reducing the risk of overpressure events and frequent automatic venting. The threaded connection enables simple integration into existing pipework and quick replacement or retrofitting when required.
Suitable for
Closed central heating systems in residential buildings
Small commercial heating installations
Boiler rooms and plant rooms requiring pressure compensation
Replacement of worn or undersized expansion vessels
Key specifications
Type: diaphragm/membrane expansion vessel suitable for closed heating systems
Nominal volume: 200 litres
Connection: threaded mounting for pipeline integration
Function: absorbs thermal expansion and pressure fluctuations to stabilise system pressure
Application: central heating (C.O.) systems in domestic and light commercial environments
How to use
Position the Reflex N 200 L expansion vessel at an accessible mounting point in the heating circuit, typically near the boiler or circulating pump. Ensure the system is depressurised and cooled before installation. Connect the vessel using the threaded connection to the appropriate pipework and secure all joints. Check and adjust the pre-charge pressure of the air side according to the static system pressure and manufacturer recommendations before bringing the system back into service. After installation, bleed any trapped air from the heating circuit and verify stable operating pressure during a full heat cycle.
Usage recommendations
Check the vessel’s pre-charge pressure periodically and adjust to match the static pressure of the heating system. Inspect for external damage, corrosion at connections, and secure mounting. For systems with water treatment or special fluids, confirm material compatibility. For complex installations or uncertainty about sizing and pre-charge values, consult a qualified heating engineer.
