Low-Maintenance Dry Fire Sprinkler
CA Dry Fire Sprinklers are designed to provide an efficient and reliable fire protection solution for environments where water supply lines may be subject to freezing or where a delay in water flow is desirable until a fire is confirmed. These sprinklers are equipped with a thermally sensitive element that releases to allow water flow when the environment reaches a critical temperature.
