What kind of water delivery system does the Bresnan nozzle employ?

The Bresnan nozzle utilizes a screen that disperses water over a large surface area, making it particularly effective for applications that require broad coverage. This design allows for a more efficient use of water by creating a wide, fan-like spray that can cover extensive areas, which is beneficial in fire suppression situations when rapid cooling of large surfaces is necessary.

This nozzle is versatile, capable of adapting to various firefighting scenarios, but its primary advantage lies in its ability to provide a more even distribution of water compared to nozzles that produce a singular, concentrated stream. Therefore, the employment of a screen in the Bresnan nozzle enhances the effectiveness of firefighting strategies, especially in conditions where rapid surface cooling is crucial or where the fire spreads across a wide area.
