Dry sprinkler ESFR-17 series

storage

TYCO Model ESFR-17 Dry Type Pendent Sprinklers are Early Suppression, Fast Response (ESFR) sprinklers having a nominal K-factor of 16.8. They are suppression mode sprinklers that are especially advantageous as a means of eliminating in-rack sprinklers when protecting high-piled box-in-box refrigerated storage areas. The Model ESFR-17 Dry Type Pendent Sprinkler is FM Approved and has successfully undergone full-scale fire testing at FM Global, when used in conformance with applicable FM Global Property Loss Prevention Data Sheets. The Model ESFR-17 Dry Type Sprinkler consists of an ESFR sprinkler permanently secured to a sprinkler drop featuring an inlet with both grooved and threaded connections. The drop between the inlet and sprinkler remains dry until the sprinkler operates, allowing for a pendent sprinkler installation on a wet pipe sprinkler system where the dry drop and sprinkler are located in an area subjected to freezing temperatures. The Model ESFR-17 Dry Type Sprinklers are primarily used for ceiling only sprinkler protection (i.e., no need for in-rack sprinklers) and used to protect solid piled, palletized, and rack storage that is subject to freezing temperatures. The water supply is provided from a wet pipe system located outside of the refrigerated storage area. The Model ESFR-17 Dry Type Sprinklers feature all of the same design criteria as 16.8 K-factor ESFR Pendent Sprinklers, and substantially lowers the end head pressure requirement as compared to the 14.0 K-factor ESFR Dry Type Pendent Sprinklers.
