  • Senju Sprinkler has over 40 years of experience in designing and manufacturing reliable fire suppression products. These products have passed vigorous performance tests and met universal quality standards. By exclusively using solder as the thermal sensor for fire detection, these sprinkler heads withstand the test of time and perform without fail in case of a fire. The creative integration of advanced technologies in mechanical engineering, polymer chemistry, and hydrodynamics within an eco-friendly framework is what makes Senju sprinkler heads truly one of a kind. Senju Sprinkler heads also provide a safety feature as the sprinkler’s deflector and delicate inner components are protected from the moment they are packaged at our manufacturing facility to when they are ready to be trimmed.
