Diaphragm expansion vessel REFLEX N-250, 250L, 6 bar / 70°C, threaded connection male thread R1", light grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8214300

Diaphragm expansion vessel – stability and safety of the installation

This REFLEX N-250 diaphragm expansion vessel, with a capacity of 250 liters, is designed for use in closed heating and cooling systems. Its membrane-based design allows for compensation of liquid expansion and maintains stable pressure in the system. This vessel is a solid element ensuring safe and efficient operation of the installation, both in residential and industrial buildings.

Construction and application

The REFLEX N-250 is characterized by a durable welded construction, coated with a gray paint finish. It has a non-removable half-membrane, which simplifies operation and minimizes the risk of failure. Designed for standing installation (on welded legs), which facilitates its integration with existing infrastructure. A threaded GZ R1” connection provides easy and tight installation in the system. The expansion vessel is crucial for protecting installation components from damage caused by pressure fluctuations, and also prevents noise associated with fluid flow.

Key features and benefits

• High capacity (250L): Provides effective compensation for liquid expansion in larger heating and cooling systems.
• Durable construction: Welded housing guarantees long-lasting and reliable operation even in difficult operating conditions.
• Non-removable membrane: Eliminates the need for regular membrane replacement, reducing operating costs and simplifying servicing.
• Wide operating 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 heating systems.
• Safety confirmed by standards: Compliance with PN-EN 13831 and Directive 2014/68/EU (concerning pressure equipment) guarantees a high level of safety.
• Threaded connection GZ R1": Enables quick and easy installation in an existing installation without the need for additional adapters.
• Working pressure 6 bar: Suitable for most standard heating and cooling installations.
• Height 888 mm and diameter 634 mm: Dimensions allow the vessel to be adapted to the available technical space.
• Initial pressure 1.5 bar: Optimal setting of the initial pressure ensures correct operation of the expansion vessel from the beginning of operation.

Let's remember that proper selection of the expansion vessel is crucial for the reliable operation of the entire heating or cooling system. Choosing REFLEX N-250, you invest in durability, safety and comfort of use for years to come.
