Cardox is a pressurised CO2 blasting system designed to clear blockages in a wide range of bulk material process systems. 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 C02 – now 660 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) producing traverse forces up to 15 tons. This all takes place in milliseconds. Absafe is the Australian Distributor for ATD Cardox Pressurised CO2 blasting systems.

Absafe also supplies and installs external permanent Cardox systems as well as supplying all training and certification for your staff 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.
