Upright sprinkler ESFR-17

storage

TYCO Model ESFR-17 Upright Sprinklers are Early Suppression, Fast Response (ESFR) sprinklers having a nominal K-factor of 16.8 (Ref. Figure 1). They are suppression mode sprinklers that are especially advantageous as a means of eliminating in-rack sprinklers when protecting high-piled storage. Model ESFR-17 Sprinklers are primarily used for ceiling-only sprinkler protection of, but not limited to, the following storage applications: • most encapsulated or non-encapsulated common materials including cartoned, unexpanded plastics • cartoned, expanded plastics • some storage arrangements of rubber tires and roll paper For more specific criteria, refer to Table A in this technical data sheet as well as the applicable design standard. The Model ESFR-17 Upright Sprinklers provide the system designer with an upright option to the traditional pendent ESFR Sprinklers. With a K-factor of 16.8, Model ESFR-17 Sprinklers provide system designers with hydraulic and sprinkler placement options not presently available to traditional ESFR Sprinklers having a K-factor of 14.0. In particular, the Model ESFR-17 Upright Sprinklers are designed to operate at substantially lower-end head pressures compared to ESFR Sprinklers with 14.0 K-factor. This feature offers flexibility when sizing system piping and positioning the system piping with respect to the ceiling. Applications for the TYCO ESFR Sprinklers are expanding beyond currently recognized installation standards.
