ESFR-17 K17 (imperial) early suppression fast response upright sprinkler head
Product Description
The ESFR-17 downdraught sprinkler head (see Figure 1) is an early suppression, fast response sprinkler head (K=242) that has particular advantages for protecting high palletized warehouses without the need for in-shelf sprinklers.
The ESFR-17 sagging nozzle is mainly used to protect most of the general materials with or without film encapsulation, including non-foamed plastics packaged in cardboard boxes with a stack height of 10.7 m and a roof height of 12.2 m. It can also be used to protect paper warehouses and rubber tire warehouses with cylindrical packaging, with a stack height and a roof height of 7.6 m. The ESFR-17 sagging nozzle can be used to protect paper warehouses and rubber tire warehouses with cylindrical packaging, with a stack height and a roof height of 7.6 m. For details of goods height, roof height and hydraulic calculation parameters, please refer to the correspondence.
The distance of the centerline of the heat element of the ESFR-17 drop-type sprinkler head from the roof panel is 305 mm and the distance is 102 mm.
The ESFR-17 Drop Sprinkler Head must be installed and maintained in accordance with the datasheet, NFPA standards and FM requirements. Incorrect installation and maintenance can reduce the fire suppression performance of the sprinkler head or even damage the sprinkler head.
Action: A fusible link assembly consists of two equal lengths connected by a thin layer of solder. When the action temperature is reached, the solder joints fuse and the two equal lengths separate, activating the sprinkler head to sprinkle water.
Based on new fire suppression tests that are constantly being conducted, the ESFR-17 Sagging Sprinkler Head is being used beyond its current approved limits.
