Indirect High Pressure (IHP) CO2 Systems are mostly used enclosed Electrical Equipments, Machinaries & Panels. Carbon dioxide (CO2) is a colorless, odorless,electrically non-conductive gas that is highly effective at suppressing a wide variety of Class A, B, and C fire. In areas with delicate electronic equipment, such as server rooms and data rooms,and storage areas with potentially combustible materials, sprinkler systems are not the ideal extinguishing agent. Typically, in those environments with valuable machinery and lots of people working you will find clean agent fire suppression systems. These use manufactured, inert gasses to suppress fires. However, in areas with no building personnel like engine rooms, power stations, and around large industrial machines, CO2 fire suppression systems may be the most effective fire protection systems.
