This document summarizes the Cardox technology provided by ATD Pressure Gas System for safely removing material build-up and blockages in industrial processes. Cardox uses pressurized carbon dioxide gas to clear obstructions remotely and safely in just minutes, reducing downtime compared to alternative methods. The system is designed to target build-up while protecting refractory and vessel walls. ATD provides equipment, training, and support to over 300 customers worldwide handling a variety of materials.

5. How does a Cardox Tube Work?
The Cardox Tube is loaded with a chemical Pressure Gas
Generator and is then sealed with the Tube Head. The
Discharge side of the tube is loaded with a Copper Washer
and Shear Disc, followed by the operator’s choice of
Discharge Head. After the tube is loaded it is then filled
with liquid CO2.

6. Loading the Tube with
Generator, Copper Washer and
Shear disc. This takes about
two minutes.
Filling The Tube with liquid CO₂.
This takes about 30 seconds.
Loading & Filling Tube

7. Three Main Components
Gripcase
Cardox Tube
Base
Socket
The Base Socket is installed on the outside
of the vessel wall in the location where the
internal material build-up is to be removed.
The Gripcase safely holds the
tube in place while it is
activated.
The Cardox Tube removes the unwanted build-up with a
high pressure blast of inert gaseous C0₂.

8. The operator detonates the Tube from a safe predetermined location. When
detonated, the Chemical Generator creates heat, converting the liquid CO2 to
Gaseous CO2 in 20 milliseconds. It expands at over 500 times its original volume and
the gas ruptures the shear disc at 37,000 psi, producing traverse forces up to 15
tons. The CO2 discharge is deflected by the Discharge Head (type depending on
application) removing the build-up from the refractory/vessel wall.
When the Tube is Activated

9. “We were experiencing funnel flow (vs. mass flow)
which leads to rat-holes putting the site at
operational risk. We originally brought in a firm,
that will remain nameless to clear the rat-hole in
an alternate way than yours. This was costly,
ineffective, and frankly I believe that firm was
milking the job. When we contacted John Stulack
he responded to our needs quickly and
professionally with his mind on safety. His use of
the Cardox System has kept the coal flowing in our
silos and has relieved a great deal of stress for the
people working in this power plant, not the least
of which is mine. John is experienced, courteous
and direct which is refreshing. He has helped us
numerous times and without his dedication I have
no doubt we would have process interruptions.” –

11. ATD Revolutionized Cardox technology 60 years ago by
removing it from the coal mine and adapting it for on line
build-up removal for industrial processes. ATD is
revolutionizing Cardox once again with new technology
that increases safety while increasing your productivity.

12. Keep Your Silos Flowing with ATD Cardox
Whether it is just residual material, funnel flow chokes, bridging,
plugging, or frozen coal. Cardox can get your silos/bunkers flowing
safely and quickly.
Many silos that were built years ago were not designed to handle
many of the types of materials that are being stored today. Cardox
technology is safe to use in coal as it clears the blockage with high
pressure inert gaseous CO₂.

14. ATD Cardox
in Action

15. Basic Procedure
Remove Locking Plate from Base Socket and insert the Drill Guide.

16. Basic Procedure
A Bore is created in the material build-up with a Rock Drill or bar.
Softer material build-up may not require any drilling.

17. Basic Procedure
The loaded Cardox Tube is inserted into the Base Socket at a
predetermined depth and locked in place with the Grip Case.
The detonating wires are now connected.

18. Basic Procedure
The tube is safely activated remotely.

19. How do we protect the refractory and Vessel
Wall?
Our ATD Pressure Gas system is
specifically designed to insure there
is no damage to the refractory or
vessel wall while targeting the
build-up.
ATD also offers custom Discharge
Tubes that insure the operator
inserts the tube at the correct
depth. Our specialized Discharge
Tubes come in a variety of types for
your specific application. Heat
resistant Tubes and Straight Shot
type are also now available!

20. Advantages using Cardox Technology
Safety! Material Build-up is removed from the outside of
the vessel wall. The operator is in a safe area when the
Cardox Tube is activated.
Cardox is safe to use in nearly every process and material as the
discharge is inert gaseous CO₂.
The system is specifically designed to insure there is no
damage to the refractory or vessel wall while targeting
the build-up.
Down time is drastically reduced. Removal of deposits in
most applications is achieved in just minutes.
Using Cardox Technology proactively prevents build-up from
becoming problematic.

21. Removing build-up without Cardox
