Diaphragm expansion vessel REFLEX N-500, 500L, 6 bar / 70°C, threaded connection male thread R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8218300

Expansion vessel – stability and safety of the installation

The REFLEX N-500 expansion vessel is a key element of every closed heating and cooling system. Its task is to compensate for the expansion of the liquid, maintain stable pressure in the installation and protect against damage caused by pressure fluctuations. This solution is dedicated to both professional installers and users who value reliability and long-term system operation.

Construction and application

The REFLEX N-500 vessel is characterized by a solid standing construction, which facilitates installation and ensures stability. Made of high-quality materials, coated with a gray paint finish, it perfectly fits the aesthetics of any boiler room. A threaded GZ R1” connection allows for easy and tight connection to the installation. A capacity of 500 liters makes it an ideal choice for larger heating and cooling systems where a large volume reserve is required.

Inside the vessel there is a non-replaceable membrane that separates water from air, preventing gas from entering the water and maintaining its properties. This ensures that the water in the installation remains clean and effective. The vessel meets the requirements of PN-EN 13831 and has an approval in accordance with the pressure equipment directive 2014/68/EU – which guarantees its safety and reliability.
