The CD690 cleaning unit is a highly specialized installation for removing of activated carbon from reactor vessels at oil refineries. By means of a high pressure of max. 850 bar water is injected by drill tubes to a nozzle where jets of water remove the activated carbon from the reactor vessels.

Operator convenience & comfort / Advantages

To meet local safety regulations of the refinery the CD690 cleaning unit is tested and provided with a ATEX cat. II 3G IIC T3 safety norm. Also a SIR safety test has been carried out, which ensures that all parts of the installation meet the safety regulations.

A drillpipe carrousel and drillhead side-shift are installed on the installation which makes manual handling of drillpipes a thing of the past. At the bottom of the mast a double breaking clamp is installed for breaking of drillpipe connections.

The installation is mounted in a hinged hoisting frame which makes installing of the installation on the reactor vessel easy.
