The Central Model ESFR-1 Early
Suppression Fast Response
Automatic Sprinkler has been
designed to meet high challenge fire
hazards.
The Model ESFR-1 utilizes a
160°F/71°C or a 212°F/100°C Fast
Response solder link, giving the
sprinkler the required fast response
characteristics.
The fast response, combined with
water droplet size and velocity
provide early suppression to high
challenge fires.
The ESFR-1 is approved for use with
storage up to 35 feet in 40 foot
buildings and 25 feet in 30 foot
buildings, as referenced in the NFPA
Standards, Underwriter's
Laboratories and Factory Mutual's
installation standards.
A head guard is available for use with
the ESFR-1. It must be assembled at
the factory, so be sure to specify it
when ordering.
