Fluoro-K™ Clean Agent
Advanced Clean Agent Fire Suppression with Low Environmental Impact
Fluoro-K™ Clean Agent is KiddeFenwal’s proprietary FK-5-1-12 clean agent designed to provide fast, effective fire suppression while minimizing environmental impact and protecting sensitive assets.
Fluoro-K™ extinguishes fire primarily through heat absorption, allowing fires to be suppressed quickly without leaving residue or causing damage to electronic equipment, critical infrastructure, or valuable materials. When applied as part of a properly engineered system, Fluoro-K™ supports safe use in normally occupied spaces while enabling rapid system recovery and minimal downtime.
Fluoro-K™ is approved for use within KiddeFenwal engineered clean agent suppression systems and delivery platforms, including ADS™, ECS™-500, and ECS™ 360, providing flexibility across a wide range of applications and enclosure sizes.
