Cardox® Low-Pressure CO2 Fire System

The CARDOX Low-Pressure Carbon Dioxide (LP CO2) System is a proven solution when used to protect areas that require multiple suppression cycles, expansion capabilities, numerous hazards or more than 5000 lbs of CO2.

LPCO2 TankCO2 is an odorless, colorless, inert gas that extinguishes fire primarily by diluting the oxygen that supports combustion. It is applied by either the “total flooding” or the “local application” method. CO2 is not recommended for normally occupied spaces, except when other means of fire protection are not effective.


Total flooding delivers CO2 into an enclosure until the fire is extinguished. For open hazards, the CO2 local application method blankets the hazard extinguishing the flames and cooling the hazard.  In “total flooding”, the enclosure of the hazard protected is flooded to a proper concentration. In “local application”, CO2 is directly applied in the proper amount at the rate required to cover the protected hazard.


We have the expertise and product line to protect a full range of hazards with vertical and horizontal storage tanks ranging from 2¾ ton to 60 ton and are available in 120, 220, 380, 460 and 575 volts, 50/60Hz, single and three-phase variants. Optional CSA and PED approved systems are also available.
