Fire water system booster set

This booster set, type ZH-CRFF/WF 2.10.4/2.2kW, is a reliable solution for increasing water pressure in fire extinguishing systems, fire water networks, and hydrant and dual-purpose installations. Equipped with two pumps, it provides a flow rate of up to 26 m³/h with a head of up to 41.2 meters. Three-phase power supply (400V) and a 2.2 kW motor power guarantee stable operation even in demanding conditions.

The set has been thoroughly tested and has all the necessary certificates – National Technical Assessment CNBOP-PIB-KOT-2022/0324-1005, National Certificate of Conformity CNBOP-PIB, and CNBOP Approval Certificate for the control and signaling device type ZHWF. Importantly, the set is suitable for use with drinking water.

Key features and applications

• High efficiency: Two pumps provide a flow rate of up to 26 m³/h, allowing for effective supply of fire protection and irrigation systems.
• High head: The maximum head of 41.2 meters allows use in buildings of varying heights and in installations with large pressure losses.
• Modbus protocol compatibility: Support for Modbus TCP and RTU protocols facilitates integration with building monitoring and control systems (BMS).
• CNBOP certification: Having the CNBOP Approval Certificate guarantees compliance with stringent safety standards and device reliability – this is crucial for installers carrying out fire projects.
• Versatile application: Ideal for fixed mist extinguishing systems, fire water networks, hydrant installations, and dual-purpose installations.
• Integration possibilities: The set can also be used in sprinkler/irrigation systems.

Important information: A testing bypass OT40 (Onninen index: DAQ079) must be ordered separately for the full functionality of the set. This is mandatory equipment for the set in accordance with the manufacturer's requirements and safety standards.
