Warehouse Fire Sprinkler System Design Information

Below are examples of common warehouse sprinkler design scenarios and the general capacity of each system.

Early Suppression Fast Response (ESFR) Systems

ESFR systems are quick responding and high volume systems that provide exceptional protection for high piled storage occupancies. They are designed to suppress the fire by discharging a large volume of water directly to the fire to reduce the heat release rate and are ideal for maximizing the high pile storage potential of your warehouse.
