1.Description

Glass ball sprinklers are the key component of sprinkler systems. It is used to sense the fire and activate the sprinkler system by bursting the glass ball to achieve fire control or fire suppression. Glass ball sprinklers are widely used to protect light and medium-level dangerous places such as hotels, commercial buildings, warehouses, garages, office buildings, hospitals, theaters, garment factories, production workshops, etc., as well as buildings with serious dangerous levels.
