Early Suppression Fast Response (ESFR) Fire Sprinkler Systems

Using early suppression fast response (ESFR) sprinkler systems, AFPG provides an exceptional fire protection alternative to traditional, in-rack sprinklers.

Rather than merely controlling the growth of a fire, as in in-rack sprinklers, ESFR systems target the fire’s origin and completely extinguish the fire by releasing large volumes of water. With quick-responding, large-volume, high-velocity sprinkler heads within ceiling spaces, our ESFR systems can enhance your entire industrial facility’s fire protection.

ESFR systems are mainly used to protect warehouses with a variety of high-piled storage, including palletized, solid pile, shelf, bin box, or rack storage of materials. The elimination of in-rack sprinklers helps warehouses avoid unintended water discharge caused by the rupture of a sprinkler or a pipe struck by a piece of material handling equipment or a pallet load. Plus, ESFR systems from AFPG allow you to rearrange storage racks without the costly reconfiguration of in-rack piping when such systems are installed in racks.

Unique ESFR Features & Benefits

• Speed – ESFR sprinkler heads sense a fire and begin spraying water in half the time of conventional heads.
• Volume – ESFR sprinkler heads release around two times the water amount (60 gallons per minute) than conventional sprinkler heads (25 to 30 gallons per minute).
• Droplet Size – ESFR sprinkler heads release larger droplets of water with greater momentum than conventional heads.
• Cost – ESFR systems provide greater fire protection than conventional systems and also cost 30 to 50 percent less.
