The Janus Fire Systems® HPCO2 Fire Extinguishing System utilizes highly pressurized carbon di- oxide as the extinguishing medium. Carbon dioxide (CO2) is a dry, inert, non-corrosive fire suppres- sion agent perfectly suited to protect high value assets in normally unoccupied and unoccupiable areas when an electrically non-conductive agent is required and where clean-up of other agents is problematic.
