The Cardox System in Action

OUR TUBES

Cardox has a variety of different Tubes for specific applications.

Tubes are filled with liquid carbon dioxide (exactly the same as a fire extinguisher). When energized by the application of a small electrical charge, the chemical Heater instantly converts the liquid carbon dioxide to 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 head to create a powerful heaving force, at pressures up to 40,000 psi (3,000 bar).

This all takes place in milliseconds.

Carbon dioxide gas is an inert gas that is commonly used in fire extinguishers, so it is safe to use without fear of generating secondary reaction with gases in the vessel/silo. In addition, the quick release of the gas refrigerates the discharge, bringing it to a temperature low enough to avoid ignition of any air-gas mixture inside the blocked vessel.

The video below shows how the Cardox system works.
