The Induction of DN20 K202 Fire Sprinkler Heads
Under normal circumstances, forede DN20 K202 Fire Sprinkler Heads will generate a lot of mechanical pressure on the moving elements when they are under working load. This series of sprinklers adopts the lever principle to reduce the force acting on the moving elements. With this structure, the mechanical pressure is reduced. Decomposed into the force on the support rod, the mechanical force of the fusible connection and the load of the flux between the fusible connection parts, so that the force of the flux is lower, and the composition of the flux required to reach the operating temperature can be avoided. Causes cold flow under stress.

1)Use the fusible alloys as sensitive components has stable performance, precise operating temperature, and fast response speed.
2)By installing ESFR sprinkler heads in the overhead system, the layered sprinkler heads on each shelf can be eliminated, thus simplifying the system and saving investment costs.
