Abstract: A fire suppression system includes a Coolant Infusion Spray Nozzle (CISN) and a Coolant Introduction Adapter Cap (CIAC). The CISN includes a water inlet and a coolant inlet. The CISN also includes a coolant infuser with infusion aperture(s) for injecting coolant into the water as it is bypassing the coolant infuser. This CISN generates a fire suppressing stream of coolant and water mixture. The CIAC supplies water and coolant to the CISN. The CIAC is coupled to a water source, and is also coupled to the CISN via hoses. The CIAC can includes an elbow for directing coolant toward the CISN.
