About Cordox Application

The Cardox system is designed to break or aerate materials by discharging Carbon Dioxide at high pressure into the material Cardox can be used for Silos, Preheaters, Cyclones, Ducts, Feed pipes, Inlet Chamber, Chutes, Clinker Cooler, Kiln, Stock Yard and many other locations.

In Cement and other manufacturing plants, the Cardox CO2 System is the most efficient and cost effective method of clearing build-up and blockages in preheaters, cyclones, inlet chambers, riser ducts, feed pipes, rotary kilns, raw feed mills, Precalciners, Coolers and anywhere in the plant’s processing line.


• No special permits for transport or storage
• Safe in gaseous mines
• Dramatic reduction in coal fines/dust
• No shock waves or vibration

Cardox tubes are filled with liquid carbon dioxide (exactly the same as a fire extinguisher). When energised by the application of a small electrical charge, the chemical heater instantly converts the liquid carbon dioxide to a gas. This conversion expands the CO2 volume and builds up pressure inside the tube until it causes the rupture disc at the end of the tube to burst. This releases the CO² – now 600 times the original volume – through a special discharge nozzle to create a powerful heaving force, at pressures up to 40,000 psi (3,000 bar). This all takes place in milliseconds.
Carbon dioxide gas is an inert gas that is commonly used in fire extinguishers, so it is safe to use without fear of generating secondary reaction with gases in the vessel / silo. In addition, the quick release of the gas refrigerates the discharge, bringing it to a temperature low enough to avoid ignition of any air-gas mixture inside the blocked vessel.

Used by all the major cement manufacturers, Cardox is widely recognised as the most efficient, reliable and cost effective method of clearing build-ups and blockages in pre- heaters, cyclones, cooler areas & rotary kilns.Cardox can quickly remove build-ups and restore plant production to optimum levels.

We specialize in Non-Explosive systems for use in clearing of build-ups and blockages in large to small Blending, Storage Silos, bunkers, Hoppers, vessels, Rotary kilns, Clinker Coolers and high heat process equipment such as pre-heaters, cyclones, feed pipes, chutes as well as provide solutions to rock breaking, concrete demolition, dimensional rock quarrying, road bed& bridge abutment Demolition, Mining, Tunnelling, even in underwater applications


Cardox technology has proven itself as a safe and controlled method for material removal. Its use is ideal for applications such as Ringsformation , chokes, and build ups in rotary kilns and high heat process equipment, as well as storage vessels, bins, silos, hoppers and bunkers. In addition to Cardox control and safety advantages, it can be applied without cooling the systems down or entering vessels. The result is less down time, minimal production loss, and the elimination of a hazardous manual labour.

Cardox can be employed for Site Preparation, Mining, Excavation, Rock breaking, Concrete demolition, Tunnelling and even underwater applications as a safe alternative to conventional explosives blasting. These highly engineered processes also provide lower decibel sound rating, low shock wave, and low debris flagration patterns, which makes them ideal for sensitive area use. In addition, both systems can be adapted to virtually any size project.
