Recently, the Nanjing Emergency Management Association announced the evaluation results of the 2025 Safety Science and Technology Achievements Awards.

The independently developed “SF-91X-100M Dual-Tethered Firefighting Water Spray System” by Nanjing Airfly Electronic Technology Co.,Ltd(Kitefly Tethered) was awarded the Second Prize of the Safety Science and Technology Progress Award.

Innovative Solution for High-Rise and Large-Scale Firefighting

Designed specifically for urban high-rise firefighting, industrial fires, and large-scale emergency rescue operations, the SF-91X-100M system is an innovative integrated solution combining:

l A tethered UAV ground power supply unit

l An integrated high-pressure water pump system

l A heavy-lift unmanned aerial platform

This configuration enables continuous, stable, and efficient aerial water spraying, significantly enhancing firefighting effectiveness while overcoming the endurance limitations of conventional battery-powered drones.

Key Highlights

✅ Continuous and Stable Power Supply

Equipped with a tethered UAV ground power station, the system provides uninterrupted power support for DJI FC100 tethered platforms, DJI M400 tethered platforms, and Kitefly Tethered UAVs, enabling hours of continuous operation and fully eliminating battery endurance constraints.

✅ High-Pressure, High-Efficiency Fire Suppression

The system integrates a 7.5 kW high-pressure water pump, delivering up to 12 MPa nozzle pressure with a spray distance exceeding 10 meters, and supports water hose heights of over 100 meters, making it suitable for high-rise buildings and industrial facilities.

✅ Strong Environmental Adaptability

With an IP65 protection rating, the system operates safely in temperatures ranging from −20°C to +50°C, and under wind conditions up to Level 6, ensuring reliable performance across diverse and complex emergency scenarios.

✅ Rapid Deployment and Easy Operation

Featuring an integrated high-pressure pump spray unit and tethered power system, the solution supports external water sources and streamlined operational procedures, enabling rapid response and sustained firefighting operations.
