We realize “In-Cabinet” suppression systems is not a type of gaseous clean agent, but it’s a fire suppression system design for specific applications. The reason for its placement here is that this is a unique system application and we were concerned that it may be missed.
In-Cabinet fire suppression systems are most likely used because it is an economical way to protect a “micro environment," such as a computer server cabinets, CNC machine, IT closets, UPS switchgear cabinets, and archive storage enclosures to name just a few. Rather than a total flood of the whole room with an agent, only the specific cabinet is protected.
Obviously, protecting only the micro environment may be a problem in the event the fire is outside the cabinet/micro environment, but the cost savings is attractive.
At the same time, an argument can be made that protecting the cabinet/micro environment is a positive. First you are protecting specifically the high value asset. Secondly, this is most likely where a fire would have the highest probability of starting, and the suppression system is right there at the fire source.
