KalpEX CO2 type Fire Extinguishers are environmentally safe and designed to suppress the fires where Class B, C and Electrically energized fires could occur. CO2 Extinguishers are advisable to use in Indoors where wind and drafts doesn’t affect discharge and where clean medium is required which doesn’t leave residue. Carbon Dioxide is discharged as a white cloud of “snow” which smothers a fire by eliminating oxygen. It is effective for Class B flammable liquids and is electrically non- conductive. Carbon Dioxide is a clean, non-contaminating, odorless gas.
