Diaphragm expansion vessel REFLEX G-500, 500L, 6 bar / 70°C, threaded connection G1", light grey, for heating and cooling systems, standing, with replaceable membrane 8521705

Diaphragm expansion vessel – stability and safety of the installation

The REFLEX G-500 expansion vessel is a key element of closed heating and cooling systems, ensuring compensation for liquid expansion and maintaining optimal pressure. Its construction, based on a membrane separating water from gas, minimizes the risk of corrosion and ensures long-term reliability. This is an ideal solution for both professional installers and users who value the stability and safety of the system.

Construction and application

The REFLEX G-500 diaphragm vessel is characterized by a solid construction in accordance with PN-EN 13831 and VDI 4708/AD 2000 standards, confirmed by approval for use in accordance with the Pressure Equipment Directive 2014/68/EU. Made of high-quality materials, with a durable external coating, it is resistant to corrosion and mechanical damage. The replaceable membrane ensures easy maintenance and extends the life of the device. A threaded G1” connection facilitates integration with the existing installation.

• Capacity: 500 liters – suitable for medium and large heating and cooling installations.
• Initial pressure: 3.5 bar – ensures optimal operating conditions in typical heating systems.
