The fixed differential by-pass kit designed for the 662 series distribution manifolds is a specially engineered accessory that ensures smooth integration within modern heating systems, It is supplied with a flexible hose that allows easier positioning during installation and provides better adaptability to the actual layout of the system’s flow and return piping.

This design helps achieve a more practical and flexible installation process, especially in situations where alignment between manifold brackets and piping routes requires adjustment, The flexible connection simplifies fitting and reduces installation constraints, making the overall system assembly more efficient.

The kit operates with a fixed differential pressure setting of 20 kPa (2000 mm water gauge), which provides a stable and consistent pressure balance within the system, This fixed value ensures uniform operating conditions across the heating network, helping maintain steady hydraulic behavior during operation.

It is designed to perform reliably under demanding technical conditions, with a maximum working pressure of 10 bar, making it suitable for a wide range of heating applications, In addition, it operates within a temperature range of 0°C to 100°C, allowing it to be used in both low-temperature and high-temperature system environments without compromising performance.

The construction and design of the by-pass kit ensure compatibility specifically with the 662 series distribution manifolds, allowing seamless integration without the need for modifications, Its compact structure and flexible hose arrangement make it suitable for different installation configurations while maintaining a clean and organized system layout.

Overall, the fixed differential by-pass kit provides a well-balanced combination of flexibility, durability, and stable operating parameters, It is designed to fit modern heating system requirements where precision installation and consistent system conditions are essential for long-term reliability and performance.
