What type of sprinkler heads are used to counteract strong updrafts during high challenge fires?

Large drop heads are specifically designed to combat strong updrafts during high challenge fires. These sprinkler heads are equipped with a larger surface area that allows for increased water discharge, which is particularly effective in overcoming the upward movement of heat and smoke associated with intense fires. The design helps to deliver a concentrated and directed water supply to the burning area, thereby maximizing the cooling effect on the flames and enhancing fire suppression capabilities.

In high challenge fire situations, where the environment is volatile and combustion can create significant updrafts, the larger drop heads can maintain effective water distribution within the fire zone and prevent the fire from escalating. This is crucial for maintaining control over a fire's spread and ensuring the safety of firefighters and occupants in the vicinity.
