Diaphragm expansion vessel REFLEX G-200, 200L, 6 bar / 70°C, threaded connection G1 1/4", light grey, for heating and cooling systems, standing, with replaceable membrane 8519100

Expansion vessels – stabilization and safety of the installation

The REFLEX G-200 diaphragm expansion vessel is a key component of closed heating and cooling systems, ensuring pressure stability and safe operation. The device compensates for changes in liquid volume due to temperature fluctuations, protecting installation components from damage caused by excessive pressure. The design with a replaceable diaphragm guarantees long-lasting and reliable operation.

Construction and operating principle

The REFLEX G-200 expansion vessel uses a diaphragm to separate the water part from the gas part. This construction prevents gas from penetrating the water, maintaining its physical and chemical properties at an optimal level. The water space is connected to the installation via a threaded connection G1 1/4", which facilitates installation and integration with the existing system. The vessel is designed for standing installation, which ensures convenient installation and servicing.

Application and benefits

• Versatility: ideal for use in both heating and cooling systems.
• Safety: protection of the installation against excessive pressure and potential failures.
• Durability: solid construction with high-quality materials ensures a long service life of the device.
• Replaceable diaphragm: the possibility of replacing the diaphragm allows extending the service life of the vessel without having to replace the entire device.
• Wide temperature range: permissible operating temperature up to 70°C and maximum system temperature of 120°C allow use in various working conditions.
• Compliance with standards: the product meets the requirements of PN-EN 13831 and the Pressure Equipment Directive 2014/68/EU, which guarantees its safety and reliability.
• Capacity tailored to needs: a capacity of 200 liters makes the vessel suitable for medium and large installations.
• Pressure resistance: The maximum working pressure is 6 bar, ensuring safe operation under standard operating conditions.

Additional information: The initial pressure of the vessel is 3.5 bar, and its height is 972 mm with a diameter of 634 mm. The painted external surface provides corrosion resistance and an aesthetic appearance. Remember to regularly check the condition of the expansion vessel and the diaphragm to ensure its proper operation and long-term use.
