Diaphragm expansion vessel REFLEX N-200, 200L, 6 bar / 70 °C, GZ R1 threaded connection, light gray, for heating and cooling systems, standing, with non-replaceable semi-membrane 8213300

Diaphragm expansion vessel – stability and safety of the installation

The REFLEX N-200 expansion vessel is a key element of closed heating and cooling systems, ensuring stable working pressure. The device compensates for changes in the volume of the heating medium resulting from temperature fluctuations, protecting installation components from damage caused by excessive pressure. Thanks to the use of a diaphragm, the water in the installation remains separated from the gas cushion, preventing gas from penetrating the water and maintaining its properties.

Construction and parameters

The REFLEX N-200 vessel is characterized by a solid construction adapted to work in demanding conditions. Made of high-quality materials, it ensures long-lasting and trouble-free operation. A capacity of 200 liters makes it an ideal solution for both domestic and public utility installations. A threaded GZ R1" connection facilitates installation and integration with the existing system.

• Nominal capacity: 200 liters – provides adequate volume reserve for pressure stabilization.
• Pre-charge pressure: 1.5 bar – the factory-set pre-charge pressure optimizes the vessel's operation in typical installations.
• Maximum permissible working pressure: 6 bar – ensures safe operation in standard heating and cooling systems.
• Maximum permissible working temperature: 70°C – allows use in most typical installations.
• Height: 758 mm, diameter: 634 mm - dimensions facilitating integration with existing infrastructure.
• Non-replaceable diaphragm: Compliance with PN-EN 13831 standard guarantees high quality and reliability of the diaphragm, eliminating the need for its replacement during operation.

Application and benefits

The REFLEX N-200 expansion vessel finds wide application in:

• Central heating installations: Ensures stable working pressure and protects installation components from damage.
• Cooling systems: Compensates for changes in the volume of the cooling medium, ensuring optimal system performance.
• Solar installations: Stabilizes the pressure in the solar circuit, increasing system efficiency.

Using this vessel translates to:

• Extended lifespan of installation components: Stable pressure reduces mechanical stress on pipes, valves and other components.
• Increased comfort of use: Eliminates noise and pulsations in the installation caused by pressure fluctuations.
• Safety of use: Protects against failures caused by excessive pressure or overheating.
• Compliance with standards: Meets the requirements of the Pressure Equipment Directive 2014/68/EU and PN-EN 13831 standard, which guarantees the safety and reliability of the device.
