means of eliminating in-rack sprinklers
when protecting high-piled storage.
Model ESFR-17 Sprinklers
primarily used for ceiling-only sprin-
kler protection of (but not limited to)
the following storage applications:
• Most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics.
• Cartoned, expanded plastics.
• Some storage arrangements of rub-

For more specific criteria, refer to
Table 1 in this data sheet as well as
the applicable design standard.
The Model ESFR-17 Upright Sprin-
