How it works

Breaking Barriers Safely: Cardox – The Reliable Choice When Traditional Explosives Can’t Be Used

The Cardox System is a high-pressure blockage clearing system that does not require explosives. It works by using specialised tubes for distinct applications. These tubes are filled with liquid carbon dioxide, akin to a fire extinguisher, and can be activated using a small electrical charge. The resulting gas expansion exerts a powerful force, clearing blockages rapidly and safely.

Cardox: Where Safety Meets Efficiency and Speed

The Cardox system offers immediate operation upon activation with minimal setup time required, as it takes just one minute to fill a tube. With one tube locked into a vessel, large areas can be cleared in a matter of seconds, and activation can be directed to target problematic areas. Additionally, the system has no effect on refractory with the correct application, and the treated tubes are durable enough to withstand harsh operating conditions.

Less downtime and no need for manual cleaning

One tube can remove several manual hours of cleaning, and unlike water jetting systems for example, there is no prolonged exposure to heat. The tube can be placed at the centre of build-up, unlike blasters, and there is no blowback on operators, ensuring maximum safety during use.

Unmatched Experience in clearing build-up and blockages

With 60+ years of experience in the cement industry alone, Cardox International remains the premier manufacturer and supplier of Cardox. Our clients attest that the Cardox System’s quick ROI makes it a smart investment, as it eliminates build-ups only as needed, with minimal running and maintenance costs.

As pioneers of the Cardox System, our expertise and innovation remain unmatched.

In a League of Their Own: Cardox International Drives Innovation Beyond Imitation.
