ESFR fire Sprinkler, denotes a special type of fire sprinkler.
Early Suppression Fast Response sprinkler heads were developed in the 1990s to take advantage of the latest fast-response fire sprinkler technology to provide fire suppression of specific high-challenge fire hazards. The sprinklers are specifically designed to fully suppress a fire that is within the design limits of the piping system. Prior to the introduction of these sprinklers, protection systems were designed to control fires until the arrival of the fire department.
