Clean Agent Suppression Systems
FM-200 (HFC-227ea) is the trademark name for heptafluoropropane. FM-200 provides superior fire protection in a wide range of applications from sensitive electrical equipment to industrial applications using flammable liquids. FM-200 has zero ozone-depleting potential, low global warming potential, and a short atmospheric lifetime. FM-200 is also a widely accepted replacement for Halon 1301.
FM-200 is an odorless, colorless, liquefied compressed gas, which discharges as an electrically non-conductive vapor that is clear and does not obscure vision. FM-200 leaves no residue and has an acceptable toxicity level for use in occupied spaces at the appropriate design concentration. FM-200 extinguishes a fire by both mechanical and chemical means. The primary means to extinguish the fire is by cooling, i.e., by the removal of heat to a point where combustion cannot occur. Upon the detection of a fire, the gas is discharged into the hazard through a system of piping and nozzles. FM-200 is stored in pressurized cylinders. The FM-200 agent and associated system components are UL listed and FM approved.
HFC-125 (FE-25) is the trademark name for pentafluoroethane. Like FM-200, HFC-125 provides superior fire protection in a wide range of applications from sensitive electrical equipment to industrial applications using flammable liquids. HFC-125 has zero ozone-depleting potential, low global warming potential, and a short atmospheric lifetime. HFC-125 is also a widely accepted replacement for Halon 1301.
HFC-125 systems require 20% less agent per cubic foot/meter than FM-200 systems. HFC-125's superior properties allow use of smaller diameter piping over long distances, creating a more cost-effective system. HFC-125 and FM-200 have identical extinguishing mechanisms, however the physical properties of HFC-125 makes it superior to FM-200 by way of design, agent quantity, and overall environmental impact. The HFC-125 agent and associated system components are UL listed and FM approved. The standard for clean agent systems is NFPA 2001.
The Kidde Clean Agent ADS System with Novec 1230 Fluid combines 3M™ Novec™ 1230 Fire Protection Fluid stored at 360 PSI with Nitrogen at 1,800 PSI. This results in the best coverage, highest nozzle, smallest diameter pipe and longest pipe runs.
Finding the proper storage area for your clean agent cylinders near your protected space can be problematic. With the Kidde ADS system, the cylinders can be stored more than 200 feet from the protected space. This gives you the flexibility to protect multiple hazards from a single cylinder bank location. Piping runs can be reduced by adding directional valves at strategic locations. If space is not a restriction, placement in or near the hazard area allows the smallest possible pipe diameter, thereby lowering your piping costs.
These characteristics allow the Kidde ADS System with Novec 1230 Fluid to be a virtual “drop-in” replacement for existing Halon 1301 systems. Most installations will require only new nozzles and agent storage cylinders and can use most of the existing pipework – providing substantial savings when retrofitting an existing system.
Kidde ADS System with 3M™ Novec™ 1230 Fire Protection Fluid Features:
• Increased agent flow rates and distances provide better coverage for larger hazard areas
• Smaller piping diameter results in installation cost savings
• Enhanced performance and versatility – use with 3-way directional valves for economic protection of multiple enclosures
• Nozzle placement up to a height of 18’ 6”
• Nozzle coverage area of 42’ 6” x 42’ 6”
• Virtual “drop-in” replacement for existing Halon 1301 installations – uses existing piping, changes may be limited to replacement of agent storage cylinders and nozzles
