what is esfr sprinkler
Early Suppression Fast Response (ESFR) Early Suppression Fast Response (ESFR) systems are quick responding, high volume sprinkler systems that provide exception protection for high piled storage occupancies. Instead of merely controlling a fire until the original fuel source is depleted, ESFR systems are designed to suppress the fire by discharging a large volume of water directly to the fire to reduce the heat release rate.
