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.
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.

Safe, reusable system
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.
How Cardox Works?
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.
