In 2019 a new brand of the Athomic® Group appeared, AgenteLimpo®, it is exactly a Clean Agent for Fire Suppression according to NFPA2001. An innovative product, capable of extinguishing Class A, B and C fires, without leaving residues and without degrading the ozone layer. The fluid is effective for preserving people's lives and maintaining the physical integrity of Electrical Systems, Data Centers, Hospital Equipment, Archives, Collections, Safe Rooms, etc. NFPA 2001 defined the term "clean agent" as an electrically non-conductive, volatile or gaseous fire extinguishing agent that does not leave residue by evaporation, being indicated for class A, B and C. A clean agent fire fighting system takes an inert gas or a chemical that is stored in a container and discharges it, when necessary, to extinguish a fire in its initial stage. There are many benefits to using a clean agent fire fighting system. These systems are fast, effective, safe, clean and environmentally friendly. Most systems can reach concentration levels for extinction in just 10 seconds or less. The clean agents are designed to suppress the fire while it is still in its incipient stage, which means that it will suppress the fire before it grows and enters the heat / flame stage and will damage the equipment in the environment. The clean agents dispersed in a fire fighting system are safe for use in areas occupied by humans and a technology with a short or practically non-existent technology has already been developed. There is no need for cleaning after the discharge of the clean agents, because they are extremely volatile gases that do not leave residues. The FK5112 fluid offers, in the long term, a sustainable technology that has the highest safety margin, the lowest GWP (Global Warming Potential) among all the alternatives of clean chemical agents, and zero ozone depletion potential.
