Diaphragm expansion vessel REFLEX N-800, 800L, 6 bar / 70°C, threaded connection male thread R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8218500

Diaphragm expansion vessel – stability and safety of the installation

The REFLEX N-800 expansion vessel is a key component of closed heating and cooling systems, ensuring pressure stability and compensation for liquid expansion. Its task is to balance pressure fluctuations resulting from temperature changes, keeping them at a safe level. The construction based on a membrane separating water from gas prevents gas from penetrating the heating or cooling medium, which affects the efficiency and lifespan of the entire system.

Construction and application

The REFLEX N-800 vessel with a capacity of 800 liters is designed to operate at a maximum pressure of 6 bar and a temperature of up to 70°C. Made of high-quality materials, with a durable, gray painted coating, it ensures reliable operation for a long time. The standing structure on welded legs facilitates installation and provides stability. A threaded GZ R1” connection allows for easy connection to the installation.

This vessel is used in:

• Central heating systems in residential and commercial buildings
• Underfloor heating systems
• Cooling systems
• Solar systems
• Various types of heating boilers

Key features and benefits

• High capacity (800L): Ideal for larger installations where a large volume compensation is required.
• Durable membrane: Non-replaceable membrane compliant with PN-EN 13831 standard guarantees long-term and trouble-free operation. Eliminates the need for servicing in this area.
• Compliance with standards: Meets the requirements of the Pressure Equipment Directive 2014/68/EU and PN-EN 13831 standard, confirming its safety and reliability.
• Wide temperature range: Permissible operating temperature up to 70°C and maximum system temperature up to 120°C allows for use in various working conditions.
• Solid construction: Standing construction provides stability and ease of installation, especially in places with limited access.
• Threaded connection: Enables quick and easy installation in existing installations.
• Painted external coating: Provides resistance to corrosion and mechanical damage, extending the life of the vessel.

Thanks to these features, the REFLEX N-800 expansion vessel is a reliable solution for professionals and end-users looking for a safe and effective way to stabilize pressure in their heating and cooling systems.
