Diaphragm expansion vessel REFLEX N-400, 400L, 6 bar / 70°C, threaded connection male thread R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8218000

Expansion vessel with diaphragm – stability and safety of the installation

The REFLEX N-400 diaphragm expansion vessel is a key element of every closed heating and cooling system. Its task is to compensate for changes in water volume resulting from temperature fluctuations, maintaining constant pressure in the installation and ensuring its proper functioning. This protects the system components from damage caused by excessive pressure and prevents its malfunction. The N-400 model, with a capacity of 400 liters, is designed for use in larger installations where a large volume reserve is required.

This vessel is characterized by a solid construction and high quality workmanship, which guarantees its reliability and long service life. Made of durable materials, it is resistant to corrosion and high temperatures. It has a non-replaceable diaphragm, compliant with PN-EN 13831, which ensures safe and efficient operation for a long time. Approval for use is confirmed by compliance with Directive 2014/68/EU regarding pressure equipment.

Construction and operating parameters

The REFLEX N-400 vessel has a GZ R1" threaded connection, which facilitates its integration with the existing installation. Its standing construction (on welded legs) ensures stability and convenient installation. The operating parameters are 6 bar working pressure and 70°C permissible diaphragm operating temperature, and the maximum system temperature can reach 120°C. The initial pressure, factory set to 1.5 bar, ensures optimal operating conditions from the start. The dimensions of the vessel are 1102 mm in height and 740 mm in diameter.

A vessel with a capacity of 400 liters is ideal for larger heating and cooling systems. The working pressure of 6 bar ensures safety and stability in typical installations, and the GZ R1" connection facilitates installation and integration with existing infrastructure. The standing construction guarantees stability and installation convenience, and the non-replaceable diaphragm minimizes operating costs and ensures long-term reliability. Compliance with PN-EN 13831 standards and Directive 2014/68/EU guarantees safety and quality confirmed by certificates.

Thanks to these features, the REFLEX N-400 expansion vessel is a reliable solution for professionals and end-users looking for high-quality components for their heating and cooling systems. It not only ensures the proper functioning of the installation, but also protects it from potential failures, which translates into savings in the long run.
