## Long description

The Reflex N 35 expansion vessel is designed for closed heating and hot-water systems to stabilize pressure and compensate for thermal volume changes. This compact gray vessel is suitable for residential and small commercial installations where space-efficient pressure management is required. It is rated for a maximum pre-charge/operating pressure of 4 bar and can be used at temperatures up to 70°C, providing reliable protection for pumps, valves and other system components.
Advantages
The vessel offers efficient pressure stabilization in closed systems with a limited footprint, allowing installation in tight plant rooms or near boilers. Its design supports consistent system protection by compensating for expansion and reducing the risk of overpressure events. Materials and construction are selected for compatibility with typical heating and hot-water circuits, enabling long-term service under rated conditions.
Suitable for
 Residential central heating systems
 Small commercial hot-water and heating installations
 Compact boiler rooms and plant cupboards
 Systems requiring pressure compensation up to 4 bar
Key specifications
 Maximum operating pressure: 4 bar
 Maximum allowable temperature: 70°C
 Application: closed heating and hot-water systems
 Color/finish: gray
 Mounting: space-efficient compact design for wall or floor proximity installation
How to use
Install the expansion vessel in accordance with system design and local regulations, ensuring correct orientation and secure mounting close to the boiler or primary circuit. Pre-charge the vessel to the system's static pressure before filling; verify the pre-charge pressure with a suitable gauge and adjust if necessary. After filling and venting the system, check for leaks and confirm that the vessel is responding to pressure changes during heating cycles. Perform periodic inspections of the pre-charge pressure and visual condition as part of routine system maintenance.
Usage recommendations
For reliable operation, match the vessel pre-charge to the static pressure of the installation and re-check the pressure after the first heat-up cycle. Avoid exposure to temperatures and pressures above the rated limits. If the system requires higher capacity or higher temperature/pressure ratings, select a suitably larger or higher-rated expansion vessel.
