Forede Pendent ESFR fire sprinkler head
Forede Pendent ESFR fire sprinkler installed in places where the slope of the roof or ceiling of the building does not exceed 170mm / m , The sprinkler plate must be installed parallel to the ceiling or ceiling The nozzle distance should not be less than 2.4m and not more than 3.7m , When the height of the protected object is greater than 7.5m or the clearance height of the protected space is larger 9m, the nozzle distance should not be greater than 3m.
Forede Pendent ESFR fire sprinkler is mainly composed of frame, sealing element, ball seat, spring, action mechanism, molten alloy plate, screw, splash plate and so on; sprinkler using a fusible element as the active element and consisting of two identical connections Sections connected by a solder layer of fusible elements. When the operating temperature is reached, the solder layer melts, the connecting parts come apart, the sprinkler starts to spew fire.

Featured
1) Use molten alloy because sensitive components have stable performance, accurate operating temperature and fast response speed.
2) By installing ESFR sprinklers in the overhead system, the layering sprinklers on each shelf can be eliminated, thus simplifying the system and saving investment costs.
Application
Mainly used to protect most common materials covered or unfilmed, including non-foamed plastics packed in cartons. The maximum stack height is 10.5m.
- It can also be used in cylindrical and rubber packaging paper products. Tire storage.
