TY7229 Đầu Phun Sprinkler Tyco Hướng Xuống (Dry Type) K16.8

The 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. Operation The casing between the inlet and the sprinkler remains dry until the sprinkler operates. The fusible link assembly is comprised of two link halves that are joined together by a thin layer of solder. When the rated temperature is reached, the solder melts and the two link halves separate, activating the sprinkler and allowing water to flow through the casing and to the activated sprinkler.
