Robotic system for hazardous waste cleaning

KOKS SAKAL no-man entry hazardous waste cleaning robot

koks robotics sakal system hazardous waste cleaning robot

The KOKS SAKAL-system is originally designed to serve in handling and removal of hazardous and contaminated areas of storage and drain tanks in the premises of nuclear power plants where human entry is restricted by necessity because of the radiation levels present. The SAKAL is designed for heavy duty long-term deployment inside stainless steel and various other tank types in underwater conditions. 


The KOKS SAKAL-system is furthermore a proven design for heavy and hazardous industrial applications and is suitable for cleaning out areas like underground tanks or gathering pools with restricted human entry. It features a cabin for the operating crew to serve as an on-location command and control module, being able to remain on-site for as long as the job requires it.


The KOKS SAKAL-system enables its user to clean irradiated areas with restricted human entry or general waste areas where the entry of humans is undesirable, like sewage water treatment plants. Used for the cleaning during the downtime or even during operation of nuclear power plants (NPP’s) the quality, health, safety and environment (QHSE) improvements are undeniable. It will find use especially in the hard condition of doing decommission work when the older type NPP’s are being put out of operation, in cleaning the built-up sludge and debris that could not have been removed during the lifetime of the NPP. Of course this is just a grasp of the wide variety of industries which the SAKAL-system can make safer by eliminating the human out of a dangerous environment.


From the cabin the operator will control every movement of the robot which can be seen on the HD television screen, either via the onboard camera or an external camera offering aerial viewpoint. The robot is connected either to a vacuum truck which will enable large quantities of (fluid) substances to be processed in a short time and then be transported for decontamination and/or storage as per the procedures of the customer, or utilizes an onboard submersible pump to circulate the water for cleaning, waste separation and flow back into the tank.


The KOKS SAKAL-system can be fitted with various option kits which are appropriate for your needs, for varied applications.
