Dense Loading

CATcap Tubular Loading

CATnap® Catalyst Passivation

Dense loading is a technology that maximises catalyst performance and therefore the performance of the reactor itself. Commonly used in the petroleum refining and petrochemical industries.

CATcap tubular loading technology is a system which pioneers the way in which tubular reactors are loaded. Due to the success of our systems many have tried to imitate it and failed. We have found that no other technique produces the same high level of uniformity and consistent loading.

A major breakthrough in catalyst unloading technology is now available and Cat Tech are proud to be setting new standards for safety in the Industry.

CD Tech Towers


Reformer Tube Loading

Cat Tech has a deep-seated history in regards to the installation process involved with CD Tech towers.  Cat Tech & CD Tech were at the time Shell owned companies, and due to the shared ownership Cat Tech were approached to assist with the onsite installations alongside CD Tech.

Cat Tech has more experience with all licensors, units and processes in the ammonia industry than any other contractor and can deliver success on any unit or process, including refits, revamps, partial unloads, cartridge replacements and inspection or repairs under inert conditions.

Cat Tech’s patent CATcade reformer tube loading system is simple, effective and delivers high quality results in all conditions. CATcade’s patented designs reduces human error and material fatigue making it the best choice for better, faster loading and DP results.

DP Testing
