Pendent Fire Sprinkler Head ZSTX-25 Fire Sprinkler System

The Pendent fire sprinkler head is a small, compact device designed to be used in buildings containing combustible materials and to protect from heat-generating fires.Fire Sprinkler is an important part of wet-type auto spraying system.Fire sprinkler head is designed for use in highly corrosive applications where traditional wet pipe systems are not suitable.

It combines the advantages of an easy to install, low-maintenance system with the reliability of a high quality mechanical linkage, which helps to ensure that it does not react when exposed to small amounts of water. It is usually installed inside the building and structures with light fire danger, medium fire danger and heavy fire danger, such as workshop, warehouse, hotel, shop, recreational place, hospital, cinema, office building and garage.

The sprinkler is composed of sprinkler frame, sealant and glass bulb. It is to be installed in the protective district via ductwork, acting as a fire detector and auto sprayer. In case of fire inside the protective district, the atmosphere temperature rises up and the liquid inside the glass bulb expands after being heated and explodes after reaching the operating temperature of the glass ball. The sealant drops and the sprinkler sprays to the protective district for fire extinguishments subject to the preset shape of spraying.
