Diaphragm expansion vessel REFLEX S-50, 50L, 10 bar / 70°C, threaded connection R3/4", light grey, for heating, solar and cooling systems, standing, with non-replaceable semi-membrane 8209500

Expansion vessels – stabilization and safety of the installation

Expansion vessels play a key role in heating, solar and cooling systems, being responsible for compensating for changes in liquid volume resulting from temperature fluctuations. This ensures stable pressure in the installation, which translates into its reliable and safe operation. The REFLEX S-50 model is a solution designed for closed systems, providing effective protection against excessive pressure and its negative effects.

The Reflex S-50 diaphragm tank is characterized by a construction based on a membrane that separates water from gas, preventing gas from penetrating the working medium. This solution ensures long-term stability of the installation parameters. Made of high-quality materials, the tank is adapted to work in difficult conditions, including with glycol as an antifreeze agent (up to 50% content). The standing construction of the S-50 model (from a capacity of 50 liters) ensures convenient installation and stability.

• Versatile application: ideal for heating, solar and cooling installations.
• Durable membrane: non-replaceable semi-permeable membrane guarantees long-term trouble-free operation. Compliance with PN-EN 13831 standard confirms high quality and safety of use.
• Chemical resistance: possibility of use with glycol (up to 50% content) expands the scope of application of the tank.
• Safety: compliance with the EU pressure equipment directive 2014/68/EU and the CE marking demonstrate compliance with strict safety standards.
• Durability: permissible operating temperature up to 70°C and maximum system temperature 120°C ensure reliability even in demanding conditions.
• Threaded connections R3/4": facilitate integration with the existing installation.
• Gray color: aesthetic appearance and a durable epoxy coating.

REFLEX S expansion vessels are a proven choice for both professional installers and end-users looking for a reliable solution to protect their heating and solar systems. Thanks to the solid construction and compliance with applicable standards, they provide peace of mind and long-term installation efficiency. Installation is simple – tanks with a capacity of 50 liters or more are designed to be placed on the floor, which facilitates integration with the existing infrastructure.
