Description
The nozzles are designed to control the agent flow and to distribute the agent throughout the protected enclosure in a uniform, predetermined pattern and concentration. The nozzles are designed to comply with ISO 14520, EN 15004, EN 12094-7, and NFPA 2001 requirements for agent discharge.
The discharge nozzles are made of brass and are available in 180° and 360° discharge patterns. Each discharge nozzle has an internal orifice plate that controls the flow of the agent through the nozzle. The hole diameter of the orifice plate is determined by performing a hydraulic calculation using the Fike Engineered ProInert Flow Calculation program. Engineered nozzle(s) should not be ordered until the clean agent system pipe network is installed and an “As Built” hydraulic calculation is performed. Orifice plate drilling must be done at the Fike factory or at a UL-listed nozzle drill station.
