Blast. Rebuild. Repeat.
Cardox CO2 Blaster
by Pneumat
A reusable gas expansion system that fractures rock-hard material with power, safety, & control.
Blast away the problem areas holding back your operation.
Power and Control
Cardox produces a controlled release of carbon dioxide at up to 34,000 psi, with the power to fracture concrete, coal, and other rock-hard materials.
Engineered for Safety
Because it does not present a fire or explosion hazard, Cardox is widely used in locations where dust, chemicals, or hazardous combustible materials are present.
Recharge & Reuse
Pneumat's Cardox system can be refilled on-site and safely transported to wherever needed. The tubes are designed to be filled, fired, rebuilt, filled, and fired again.
Having Supplier Issues?
Pneumat has quality Cardox consumables (heaters, shear disks, etc.) ready to ship from our Minnesota-based manufacturing facility. Supplies are interchangeable with most Cardox systems. Contact us to place an order today!
How It Works
The Cardox CO2 Blasting system consists of a reusable metal tube that is secured into a vessel or directly into the material to be blasted.
Inside the high-strength steel alloy tube is a charge of liquid carbon dioxide and a chemical energizer. When remotely initiated by a small electric charge, the carbon dioxide inside the tube rapidly expands. At around 34,000 psi the pressure bursts a rupture disc and is released through the ports on the discharge head as high-velocity jets of inert gas with the power to dislodge and break up tons of material. The process occurs in less than one second – with no risk of igniting combustible materials or gasses in the vicinity.

Why Work with Pneumat?
Pneumat has led the development of Cardox technology for decades and is home to the nation's leading Cardox experts. We are the inventors of the Rapid-Fill Pump and Auto-Fill Head that revolutionized how Cardox tubes are filled, eliminating the need to keep tubes refrigerated at the worksite.
The primary advantage of the Pneumat Cardox CO2 Blasting System over competing products is the extent to which our field technicians, engineers, and machinists have collaborated to produce a system that essentially eliminates misfires. Misfires are a frustrating scenario that results in downtime, threatens worker safety, and increases operational costs.
If half your blasting attempts result in misfires, you are effectively paying twice as much for consumables. Choosing a precision-engineered Pneumat Cardox system maximizes the value of your investment for years to come.

The POWER of Cardox
Cardox blasts are often performed inside of a vessel with limited visibility. This demonstration pushing around a huge boulder shows just how much force Cardox can generate by instantaneously converting a small amount of carbon dioxide from liquid to gas.
Even with extreme heat and flame applied, Pneumat heaters will not react under normal handling conditions.
How Safe is Cardox?
Pneumat's safety heaters are a stable, non-explosive chemical energizer used to initiate a Cardox blast. They must be embedded in high-pressure CO2 in order to release their heat energy and create supercritical carbon dioxide. This allows Cardox to be deployed in high-temperature applications like a 1500° Fahrenheit (816° Celsius) kiln without the need for lengthy cooldown cycles.

Features and Benefits
When Explosives Aren't An Option, Cardox Gets The Job Done
Cardox was originally developed for mining operations, but its applications have expanded to serve many different industries.
Pneumat designs, builds, and uses all of the Cardox components we offer. Through our quality control process, tube recertification program, and in-depth training offerings, we are proud to provide our customers with the most complete Cardox solution on the market. It’s dependable, easy to use, and powerfully effective on buildup of all types.
Safely remove rock-hard buildup without hazardous explosions, shock waves, or confined space entry.
Blast in Areas You Never Thought Possible
Cardox phase-transition blasting technology was originally designed for use in coal mines, where methane and other dusts and gasses pose a constant threat of fire or explosion. Acting on natural cracks and weaknesses, Cardox dislodges stuck material by rapidly releasing a powerful shot of inert CO₂ gas at up to 34,000 psi. Using a remote detonator, your team activates the system from a safe distance and Cardox does the work, fracturing material in a controlled manner without the high-velocity shock wave of an explosive. It can even be used in hot kilns where the internal temperature can be up to 1500° Fahrenheit (816° Celsius).
Demolition Without Ignition
Conventional explosives produce combustion, shock waves, vibration, and high noise levels. They also have the potential for dangerous rock fly and come with some of the strictest regulatory compliance standards. For many applications, Pneumat’s proprietary Cardox non-detonating gas expansion system is a safe and effective alternative. Upon activation, a controlled release of inert carbon dioxide gas fractures blockages and hang-ups in bulk material handling processes without the potential for igniting combustible dusts or gasses. Concrete, coal, catalyst, hardened protein meals, and other rock-hard materials have all been safely shattered and dislodged by Cardox while vessel walls, equipment, and personnel remain protected from harm.
Endless Applications
Pneumat's carbon dioxide blasting system is widely used in cement production processes, clearing hardened material from feeders, risers, kilns, preheater/precalciner towers, and other vessels and processing equipment. Mining operations, ag processing and storage facilities, paper/pulp mills, waste handling systems, and chemical production plants also represent environments where product can solidify where dust, biogasses, or other flammable or explosive materials are present. The Pneumat Cardox CO2 Blaster works where other tools cannot – including high-temperature production systems.
