Diaphragm expansion vessel – stability and safety of the installation

The REFLEX N-18 expansion vessel is a key element of every closed heating and cooling system. Its task is to compensate for changes in fluid volume resulting from temperature changes, maintaining constant pressure in the installation and protecting it from damage. This ensures not only comfort but, above all, the safety of the entire system.

Construction and application

The Reflex N type diaphragm vessel is characterized by a solid construction and the use of a non-replaceable diaphragm that separates water from air. This prevents gas from penetrating the water, which affects its quality and system efficiency. The N-18 model with a capacity of 18 liters and a threaded GZ R3/4" connection is ideal for use in domestic installations and small commercial facilities. Made in gray color, designed for wall mounting.

Thanks to its properties, the vessel provides expansion compensation, protection against damage, long-term and trouble-free operation thanks to the non-replaceable membrane, and the ability to operate within a wide temperature range. It meets the requirements of PN-EN 13831 and has approval in accordance with the pressure equipment directive 2014/68/EU, which guarantees safety and quality. Easy installation is provided by the threaded connection.

Technical parameters and durability

The REFLEX N-18 vessel is distinguished by its high quality and durability. Made of corrosion-resistant materials, it ensures reliable operation for many years. The operating pressure of 4 bar makes it suitable for most standard heating and cooling installations. In addition, the five-year manufacturer's warranty confirms the high quality of the product and gives confidence in the purchase. A graphic nameplate and operating instructions facilitate proper operation of the device.
