Chemori5112 Clean Agent

Chemori5112 is one of the most prevalent agents used for fire suppression in the world. It is perfect for electronic equipment as it is non-conductive, non-corrosive, and free from any residue. It is composed of fluorinated ketone that is stored as a liquid before being discharged as a gas.

FK-5-1-12 works by removing the heat source from the flame, extinguishing it immediately. This is considered a safer route than other agents which remove the oxygen from the heat source, thus being unsuitable for occupied spaces.

In addition, FK-5-1-12 is safe around people and your equipment. The agent evaporates immediately after discharge, leaving no need for tedious clean-up.
