At design concentrations both the agents are safe for protecting closed areas and the discharge produces only a negligible decrease in the oxygen level. After discharge, the extinguishing agent can be dispersed by simple aeration because the clean agents quickly evaporate, there is minimal downtime as no clean-up is required. FITECH1230 agent compiles with NFPA Standard 2001: Standard for Clean Agent fire Extinguishing systems, EPA SNAP Program (Significant New Alternate Policy).
Clean agent fire suppression systems are safe to use in occupied spaces, require no clean up after discharge, and are environmentally friendly with a short to no atmospheric lifetime and a low Global Warming Potential (GWP). These systems are designed around providing total flooding protection for small enclosed areas or large rooms containing sensitive documents or equipment.
When a fire is detected by one or more of the automatic detectors or when a pull station is activated, the fire detection control panel sets off an alarm. After a brief time delay, the pressurized extinguishing agent cylinders are opened either electrically or pneumatically. The liquid extinguishing agent flows to the nozzles where it vaporizes, rapidly and effectively flooding the room.
The basic system consists of extinguishing agents stored in seamless metal cylinders. There are various types of actuators ie. Electric, Pneumatic and Manual for the actuation of the system and release of the agents into the hazard area. The agent is distributed and discharged into the hazard area through a network of pipes and nozzles. The nozzle is drilled with a fixed number of orifices designed to deliver a uniform discharge to the protected area.
The Fire extinguishing system is designed using a dedicated software for calculating the cross-section diameters of the nozzle passages to discharge the extinguishing gas into the environment in 10 seconds. Discharge time is defined as the time needed to reach 95% of minimum design concentration.
Full discharge within 10 seconds is clearly advantageous with respect to technologies that provide discharge times and consequently, extinguishment times in excess of one minute. Use of the HFC227/FK-5-1-12 extinguishing agents guarantee fast fire suppression and therefore less damage both to the protected spaces and objects and people present in the areas.
The system cylinders conform to DOT, BIS & PESO standards. The components meet the requirements of UL & TPED 2010/35/UE, of the Construction Products Directive (CPD – 89/106/CE), and of the EN 12094-series standards. The clean agent FITECH227 (HFC227ea) and FITECH1230 (FK-5-1-12) are UL recognized.
