Cement Applications of the Cardox System

Used by all the major cement manufacturers, Cardox is widely recognised as the most efficient, reliable and cost effective method of clearing build-ups and blockages in pre-heaters, cyclones,  kiln inlets, riser ducts, cooler areas & rotary kilns.

Cardox International, the original manufacturers and suppliers of Cardox has provided over 60 years of service to the cement industry.

Cardox can quickly remove build-ups and restore plant production to optimum levels at operating temperatures, with no need to sit through extended shut down while the vessel cools.

Operation: Fast, safe & simple


Unlike air-blasters where cement plants complain of ineffectiveness and report losses of efficiency of up to 75%, using Cardox there is no loss in efficiency! Each time you use a Cardox Tube you are guaranteed maximum pressure to remove the build-up. With a safe and powerful carbon dioxide blast one Cardox Tube can remove tons of build-up and you’re back up to running at full capacity, with little, or no downtime.


The Cardox System is fully approved by the UK Health & Safety Executive and certified by Delta International Products Testing Laboratories.

Cardox Tubes are classed as pressure vessel and are fully regulated under the European Pressure Vessels Directive (PED) and subsequently carry the CE quality marking.

Cardox Tubes are manufactured and tested to the European Pressure Vessel Directive.


Many of our customers report that the Cardox System pays for itself in no time at all. Cardox is only used when a build-up occurs and so the running costs can be very low. Also, maintenance costs are minimal.
