Diaphragm expansion vessel REFLEX N-140, 140L, 6 bar / 70 °C, threaded connection GZ R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8211400

Expansion vessels – stability and installation safety

The REFLEX N-140 diaphragm expansion vessel is a key component of closed heating and cooling systems, designed to compensate for changes in liquid volume due to temperature fluctuations. Its task is to maintain pressure in the installation at a safe and optimal level, protecting system components from damage. The construction with a non-removable diaphragm ensures reliable and long-lasting operation.

Construction and application

The REFLEX N-140 vessel with a capacity of 140 liters is designed for standing mounting (has welded legs). It is made of high-quality materials, which guarantees corrosion resistance and durability. It has a GZ R1" threaded connection, which facilitates integration with the existing installation. Thanks to the approval for operation at a pressure of 6 bar and a temperature of 70°C, the vessel will work in a wide range of applications – both in domestic installations and commercial facilities. It is worth remembering that the diaphragm in this model is non-replaceable, which simplifies operation and minimizes the risk of failure.

Key features and benefits

• Pressure stabilization: The vessel effectively compensates for changes in liquid volume, preventing excessive pressure increases in the installation. This translates into a longer service life of system components – pumps, valves, pipes.
• Durability and reliability: Made of high-quality materials and a non-removable diaphragm ensure long-lasting and trouble-free operation of the device.
• Wide application: Suitable for heating, cooling and solar systems.
• Safety: Compliance with PN-EN 13831 and Directive 2014/68/EU confirms a high level of safety.
• Simple installation: The GZ R1" threaded connection facilitates quick and efficient connection to the installation.
• 5-year warranty: Gives confidence in solid workmanship and peace of mind for the user.
• Graphic nameplate: Facilitates identification of technical parameters and quick reading of key information about the device.
• Improved packaging: Ensures safe transport and protection against mechanical damage during storage.

Whether you are an experienced installer or an end user, the REFLEX N-140 expansion vessel is an investment in a stable, safe and efficient operation of your heating or cooling installation. Solid construction, compliance with standards and a long-term warranty are a guarantee of peace of mind and comfort of use for many years.
