Fog stream nozzles are designed to create a highly dispersed spray of water, resulting in fine droplets. These small droplets have a greater surface area relative to their volume compared to larger water streams. This characteristic is crucial because the fine droplets enhance the ability of water to absorb heat rapidly from the burning materials, leading to faster cooling and increased effectiveness in extinguishing fires.

The design of fog stream nozzles allows them to achieve a balance between coverage and heat absorption, making them particularly useful in firefighting scenarios where quick thermal reduction is needed to control flames and protect exposed structures or personnel. The mist-like spray also assists in protecting firefighters from heat and reduces the risk of steam burns by creating a barrier between them and the fire. In contrast, other types of nozzles, such as solid stream or master streams, do not create such fine dispersion and therefore do not absorb heat at the same efficiency as fog stream nozzles.
