Product Introduction

The high-velocity water droplets emitted by the nozzle are capable of effectively penetrating the intense upward currents of hot air, commonly referred to as the "fire plume," produced by the flames. This allows the water to be delivered directly onto the surface of the burning material, facilitating rapid cooling and extinguishing of the fire.

"K25.2" refers to the flow coefficient of the nozzle, meaning that under the same pressure, it can spray more water than other smaller K-factor nozzles (such as K17). Its design goal is to sharply reduce the heat release rate and prevent reignition in the early stage of a fire, rather than mainly controlling the spread of the fire as in traditional sprinkler heads.

Product Features

• High flow coefficient.

• Rapid response: Utilizing rapid response thermal sensitive components, it can quickly activate in the early stage of a fire, seizing the best opportunity for fire suppression.

• High-momentum water droplets: Its specially designed deflector can generate water droplets with large particles and high kinetic energy. These water droplets can effectively penetrate the obstruction of the ascending air flow of the fire and directly reach the surface of the burning object for cooling.
