Cardox Co2 by Pneumat

Safely Clear Combustible Materials

If you want to make quick work of clearing blockages, plugs and chokes in your pre heater towers, silos, kilns and bins, the Cardox CO2 Blaster could be your answer.

Cardox produces a controlled release of liquid CO2 at up to 34,000 psi with the power to break concrete, coal and other rock-hard materials. Because it does not present a fire hazard, Cardox is widely used in locations where dust, chemicals or hazardous combustible materials are present.

Pneumat designs, builds and inventories all of the Cardox components we offer, in fact, we use Cardox on a daily basis in our Silo Clean Out Services. Our hands on approach led us to develop the Rapid-Fill Pump and the Auto-Fill Head that revolutionized how Cardox tubes are filled. Pneumat’s Cardox CO2 Blasting System is simple, efficient and more reliable than any other system on the market, effectively making misfires a thing of the past.

  • The most competitive price on the market for consumables
  • Guaranteed available inventory (order today/ships today)
  • Safe-reusable system
  • Interchangeable components with other systems
  • Qualified, experienced Technicians to assist with questions
  • On-site training by the Country’s leading Cardox experts

How Cardox Works

cardox co2 during after blast

The heart of Pneumat’s Cardox System is a reusable, high-strength alloy steel tube, which holds a charge of liquid carbon dioxide and a safety heater.

When the heater is remotely initiated by a small electrical charge, the CO2 reaches the shear pressure of the rupture disc (up to 34,000 psi). High-pressure CO2 is instantly released through ports of the discharge head, creating a powerful force that dislodges tons of blockage in less than a second.

Once fired, the Cardox tube is rebuilt with a new Cardox safety heater, shear disc and sealing washer and recharged with CO2 for another use.

Safe, Reusable System

Pneumat’s proprietary Cardox blasting system is a safe, effective way to clear blockages and hang-ups from a bulk materials handling line. It powerfully but gently breaks rock, concrete and other materials that have become rock-hard. Storage vessel walls are not damaged in the process. Cardox is cost-effective and safe to transport. Tubes are designed to be filled, fired, rebuilt, filled and fired again.

Designed for Use in Hazardous Environments

The gentle, hydraulic breaking force of Cardox was originally designed for use in coal mines, where volatile methane gas makes explosion a constant threat. Acting on natural cracks and weaknesses in the material, Cardox dislodges stuck material by instantaneously releasing liquid CO2 at up to 34,000 psi. Cardox does the work—creating power without the high-velocity shock waves of an explosive—while you monitor the job safely, at a distance.

Cardox Is Valued by Diverse Industries

Cardox is widely and safely used in feed mills and grain handling plants, where grain dust can be volatile and dangerous. It is safe and effective when used in preheater/precalciner systems, feeder systems, kilns, paper and pulp mills, waste handling sites and storage systems, among others. It works where other tools cannot—in high-temperature production areas and where hazardous, flammable or combustible materials are stored. The harder the material, the better Cardox works.

It’s too expensive not to fix the problem.
