Fire Water System Booster Set

This booster set, consisting of two pumps, is designed for reliable water pressure boosting in fire extinguishing systems, fire water networks, and hydrant and dual systems. It is a comprehensive solution for buildings requiring a high level of fire safety. Application in sprinkler/irrigation systems further expands its functionality.

Performance and Application

The set provides a maximum performance of 17.6 m³/h and is able to lift water to a height of 42.1 meters. The 1.1 kW motor, powered by 400 V, guarantees stable operation even with high water demand. The ability to integrate with Modbus TCP and Modbus RTU protocols allows for remote monitoring and control of the set's operation – useful for both installers and end-users in BMS (Building Management System) systems. The set is suitable for use with potable water.

Safety and Compliance

A key advantage of this set is its possession of a CNBOP Approval Certificate, confirming its compliance with stringent fire safety standards. It has received a positive assessment of its properties and holds the National Technical Assessment CNBOP-PIB-KOT-2022/0324-1005 issue 1 and the National Certificate of Conformity CNBOP-PIB. Additionally, it has a CNBOP Approval Certificate for the control and signaling device type ZHWF and a National Declaration of Performance (KDWU).

Important: A separate order for the OT40 testing bypass (Onninen index: DAQ079) is required for the full functionality of the set. This is mandatory equipment for the set.

Construction and Parameters

The set consists of two pumps, providing redundancy and increasing system reliability. Three-phase power supply (3 phases) ensures stable operation even under heavy loads. The design adapted for use with potable water makes it a universal solution for various types of buildings.
