Storage sprinkler ESFR-22

TYCO Model ESFR-22 Pendent Sprinklers are Early Suppression, Fast Response Sprinklers having a nominal K-factor of 22.4 (Ref. to Figure 1). They are suppression-mode sprinklers that are especially advantageous as a means of eliminating the use of in-rack sprinklers when protecting high-piled storage. The Model ESFR-22 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 • uncartoned (exposed) expanded plastics in accordance with NFPA 13 and FM Global standards • some storage arrangements of rubber tires, roll paper, flammable liquids, and aerosols For more specific criteria, refer to Table A as well as the applicable design standard. The Model ESFR-22 can protect a storage arrangement of 40 ft (12,2 m) with a ceiling height of 45 ft (13,7 m) without requiring in-rack sprinklers. In addition, it can be installed with a maximum deflector-to-ceiling distance of 18 in. (460 mm), Applications for TYCO ESFR Sprinklers are expanding beyond currently recognized installation standards.
