Diaphragm expansion vessel REFLEX G-300, 300L, 6 bar / 70°C, threaded connection G1 1/4", light grey, for heating and cooling systems, standing, with replaceable membrane 8519200

Diaphragm expansion vessel – stability and safety for your installation

This diaphragm expansion vessel from REFLEX, part of the G series, is designed for closed heating and cooling systems. Its function is to compensate for the thermal expansion of the heating medium, maintain stable pressure in the installation, and protect its components from damage caused by pressure fluctuations. With a capacity of 300 liters, designed to operate at a maximum pressure of 6 bar and a temperature of 70°C, it is a reliable solution for both professional installers and end-users.

Construction and application

The REFLEX G-300 expansion vessel uses a membrane to separate water from gas, preventing oxygen from entering the installation and minimizing corrosion. The solid construction, compliant with PN-EN 13831 and VDI 4708/AD 2000 standards, guarantees long-lasting and trouble-free operation. It has approval for pressure equipment 2014/68/EU, confirming its safety and compliance with European standards.

• Versatile application: ideal for central heating systems, underfloor heating and cooling installations.
• Replaceable membrane: allows for easy maintenance and extends the life of the vessel.
• Threaded connection G1 1/4 inch: ensures quick and tight installation in the system.
• Durable external coating: the painted surface protects against corrosion and mechanical damage.
• Addition of antifreeze agent: (from 25% to 50%) protects the installation from the effects of low temperatures.

Key features and benefits

The REFLEX G-300 vessel is not only an element ensuring pressure stability, but also an investment in the safety and durability of the entire heating or cooling installation. A pressure gauge protected by a metal guard makes it easy to monitor the working pressure, and the pre-pressure valve allows for precise adjustment of operating parameters to the specifics of the installation.

• Overload protection: the vessel absorbs excess energy generated during the expansion of the heating medium, protecting pipes, radiators and other installation components from damage.
• Stable pressure: ensures comfortable use and optimal performance of the heating or cooling system.
• High quality workmanship: guarantees long-lasting and trouble-free operation of the device.
• Easy installation and maintenance: thanks to the well-thought-out design and standard connections.
• Availability of spare parts: the replaceable membrane allows for repair of the vessel without having to replace the entire device.

Whether you are an experienced plumber or an end-user – the REFLEX G-300 expansion vessel is a sure choice for any demanding installation!
