Model ESFR-34 Sprinklers

The Model ESFR-34 sprinklers are advantageous when eliminating in-rack sprinklers for the protection of high-piled storage. Their heavy discharge helps attack burning fuel and protects most encapsulated or nonencapsulated common materials, including cartoned and unexpanded plastic. These suppression-mode sprinklers can protect a storage arrangement of 50 feet (15.2 meters) with a ceiling height of 55 feet (16.8 meters) without requiring in-rack sprinklers. In addition, it can be installed with a maximum centerline of a thermal sensing element-to-ceiling distance of 17 inches (432 millimeters).
