Cardox Systems Solutions

Manufactured by Cardox International Ltd, the original manufacturer of Cardox Systems Technologies.

Cardox system used to safely eliminate ledging of Granular Urea in dry storage warehouse

Non-explosive Cardox Systems are globally recognized as the most effective and reliable means of loosening accumulated powdered, granular, or solidified materials in diverse material handling and process applications. Deca is proud to partner with Cardox International, the original manufacturer, in offering the Cardox System for bin cleaning and other uses.

Cardox System solutions provide safe and economical results in clearing stubborn material build-up or blockages, and for fracturing rock or concrete in above ground, underground, or underwater applications. They are available in styles and sizes tailored to each application, and are commonly used for:

The Cardox Advantages

Because Cardox Systems work on the rapid expansion of CO2 from a liquid to a gaseous form – generating pressures up to 40,000 psi – they offer multiple advantages over other mechanical solutions or conventional explosives. 


  • SAFE. Instantaneous liquid-to-gas expansion provides a safer fracturing alternative to dynamite, and can be used safely in explosive environments and closer to sensitive areas without the same safety concerns. This is a welcomed solution for potentially explosive products such as grains, sugar, coal, fertilizers and ore powders.

Cardox CO2 System Used to Blast Granular Urea

  • TIMESAVING. With the ability to be installed from the outside of a structure at regular operating temperatures, Cardox solutions eliminate the need for extended shutdowns to cool rotary kilns. This feature enables you to remove rings or blockages in hours with one or two workers, instead of requiring multi-day shutdowns involving dozens of workers.
  • ECONOMICAL. Reusable Cardox tubes can be discharged, removed, and recharged within minutes. With a working life of more than 15 years, and the ability to be re-used by replacing just a few consumable parts, they provide years of repetitive use in blockage-clearing or fracturing applications.
  • EFFECTIVE. A few properly placed and actuated Cardox tubes can clear stubborn accumulations – such as compacted powders or hygroscopic materials in storage vessels, or ring formations in rotary kilns – all from the outside of the vessel.
  • RELIABLE. Unlike air blasters that can lose up to 75% of their efficiency in cement plant applications, Cardox tubes are guaranteed to generate maximum pressure every time.


Whatever the industry application or obstruction, Cardox Systems provide quicker and more economical solutions. 


  • STORAGE VESSELS. Powerful Cardox Systems provide the ultimate solution to clear even the most difficult of build-ups or blockages in bins, silos, hoppers, and bunkers. These include granular and powdered materials that are susceptible to accumulation, compaction, or sticking under tremendous weight or due to humid conditions. These include a variety of organic and inorganic materials: grains… flour… maize… soy… salt… sugar… DDG… cement… cement… gypsum… coal… fertilizer… catalyst… ores… and ore powders, etc.
  • ROTARY KILNS. Naturally occurring ring formations in rotary kilns have multiple causes and multiple impacts on cost-efficient productivity. Cardox Systems let you clear build-ups and blockages caused by burning zone rings, mid-kiln rings, alkali rings and mud rings, without time-consuming shutdowns for unscheduled clean-outs and replacement of damaged refractory bricks.
  • DEMOLITION. Strategically placed Cardox tubes can replace noisy and dusty conventional concrete demolition operations for quicker, easier breakdown and removal.

Here’s an example of the Cardox system at work in concrete demolition.

  • UNDERGROUND EXCAVATION. Cardox tubes deliver up to 17.5 tons of rupture pressure per square inch to simplify excavations for tunneling, foundations, quarrying, trenching, and open cuts. The ability to use them close to sensitive areas makes them the best alternative to conventional dynamite.


Here’s an example of how the Cardox system makes Face Tunneling possible in a 350′ Tunnel of Limestone Rock under sensitive structures. 

  • UNDERWATER EXCAVATION. Because they produce no shock wave and minimal vibration, Cardox solutions are completely safe for underwater excavation applications – even in close proximity to ships, structures, and sensitive areas. They generate no noise and no danger to marine life. Divers can even stay underwater during tube activation.


Here is an example of the Cardox System used in underwater excavation.

How the Cardox System Works

If you have struggled with material build-up, demolition, or excavation problems that are too time-consuming or too costly to deal with using conventional approaches, explore the possibilities of Cardox System alternatives. They provide a comprehensive solution for applications where compaction or blockages are simply too large or too entrenched to respond to industrial vibrator solutions, or where explosives are impractical to use.

The Cardox Tube

Cardox CO² systems are comprised of reusable steel tubes filled with liquid carbon dioxide, which when energized by a small electrical charge from the firing head, instantly converts into gas. The CO² volume builds up until the pressure inside the tube causes a rupture disc at the end to burst and release the gas at a controlled pressure of up to 40,000 psi. These pressures build within milliseconds and generate forces capable of dislodging and clearing stubborn build ups of rock-hard concrete, cement, and heavily compacted bulk solids — immediately returning materials such as grain, flour, maize, soy, salt, sugar, coal, fertilizers, ores, powders, and catalysts to free flowing status.

Fast, safe, and cost-effective, the powerful Cardox CO² system provides the ultimate solution to rapidly clear even the most difficult of build ups. There is no need for extended shutdowns, and carbon dioxide gas presents no risk of combustion, allowing Cardox CO² systems to be used in high temperature areas or where dust, chemicals, or hazardous materials are present. The tubes are reusable — the only consumables are heater, washers, and rupture disc — and rapid recharge minimizes disruption of plant operations.

As the premier North American supplier of Cardox CO² systems, our highly qualified technicians have the in-depth knowledge and field-proven expertise to assist you with your individual project.
