Diaphragm expansion vessel REFLEX N-1000, 1000L, 6 bar / 70 °C, threaded connection male thread R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8218600

Pressure stabilization in heating and cooling systems

The Reflex N-1000 diaphragm expansion vessel is a key component of closed heating and cooling systems, ensuring stable and safe operation. Its function is to compensate for changes in liquid volume resulting from temperature fluctuations, maintaining pressure within permissible limits. This solution is appreciated by both installers and end-users due to its reliability and long service life.

Design and application

The Reflex N-1000 is characterized by a solid welded construction, coated with a gray paint finish. It is designed in a standing version, which facilitates installation and integration with existing infrastructure. A capacity of 1000 liters makes it an ideal choice for larger installations where a large volume reserve is required. A threaded GZ R1" connection ensures easy and tight installation in the system.

Inside the vessel, there is a non-removable diaphragm that separates water from gas, preventing air from entering the installation. This design minimizes the risk of corrosion and maintains optimal system performance. The vessel complies with the PN-EN 13831 standard and has approval for use in accordance with Directive 2014/68/EU regarding pressure equipment – this guarantees safety and quality.

Key features and benefits

• High capacity: 1000 liters provides effective compensation for volume changes in large installations.
• Durable construction: Welded housing with a painted coating guarantees resistance to corrosion and mechanical damage.
• Non-removable diaphragm: Eliminates the need for servicing and replacing the diaphragm, reducing operating costs.
• Safety: Compliance with PN-EN 13831 standards and Directive 2014/68/EU ensures safe system operation.
• Wide temperature range: Permissible operating temperature up to 70°C and maximum system temperature up to 120°C allow the vessel to be used in various conditions.
• Optimal pressure: Operating pressure at 6 bar ensures stable operating conditions of the installation.
• Easy installation: Threaded GZ R1" connection facilitates integration with the existing heating or cooling system.

The Reflex N-1000 expansion vessel is an investment in the reliability and long-term operation of a heating or cooling system – for both professionals and end-users.
