Diaphragm expansion vessel REFLEX N-35, 35L, 4 bar / 70°C, threaded connection male thread R3/4", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8208401

REFLEX expansion vessels – stabilization and safety for installations

REFLEX expansion vessels from the N series are a key element of closed heating and cooling systems. Their task is to compensate for changes in water volume resulting from temperature fluctuations, maintaining pressure within the permissible range. This ensures stable and safe operation of the entire system. The membrane-based construction separates water from gas, preventing air from entering the installation and maintaining its efficiency. The N-35 model with a capacity of 35 liters is particularly recommended for installations requiring a reliable solution in a compact size.

Construction and application

The REFLEX N-35 expansion vessel is characterized by a solid standing construction, which facilitates installation and ensures stability. It is made of high-quality materials, guaranteeing durability and corrosion resistance. It has a GZ R3/4” threaded connection, allowing easy connection to an existing installation. The non-replaceable membrane, compliant with PN-EN 13831, ensures long-term and trouble-free operation of the device. The vessel is approved for operation at temperatures up to 70°C and at a pressure of 4 bar, making it a universal solution for various applications – from domestic heating systems to more extensive commercial installations.
