ESFR Sprinkler
ESFR (Early Suppression Fast Response) for high-bay warehouses
Overview
ESFR is a high-flow sprinkler system designed to suppress fire in high-bay warehouses from ceiling level without in-rack sprinklers. Large water droplets penetrate the fire plume for rapid suppression.
How it works
Ceiling-Level Suppression
High K-factor heads suppress from the ceiling without the need for in-rack sprinklers.
Fast-Response Element
A low-RTI bulb activates in the early stage of the fire.
High Flow & Pressure
Large droplets penetrate the fire plume to reach the stored load.
Storage Flexibility
Reduces the need to relocate in-rack piping when rack layouts change.
Frequently asked questions
How does ESFR differ from standard sprinklers?+
ESFR suppresses fire with high-flow large droplets; standard sprinklers usually control fire. ESFR often eliminates the need for in-rack sprinklers.
Is it suitable for any warehouse?+
Ceiling height, storage height and load type determine ESFR suitability; where unsuitable, in-rack sprinklers are designed.
