  • Designed to make decontamination easier
  • Selection of superstructures for different kinds of jobs
  • Undeniable improvement for quality, health, safety and environment (QHSE)

The KOKS SAKAL-system was originally designed for handling and removal of pollution from hazardous and contaminated storage and drain tanks at the site of nuclear power plants, where human access is necessarily restricted due to the radiation levels present. The SAKAL-system is designed for long-term use under severe conditions in stainless steel tanks and various other types of confined spaces in submerged conditions.

In addition, the KOKS SAKAL-system is a proven design for heavy and hazardous industrial applications and suitable for cleaning areas such as underground tanks or collection basins with restricted human access. The system is equipped with a cabin for the operating personnel to act as an operating and control module on site and can remain on site as long as required for the job.

The KOKS SAKAL-system enables its user to clean irradiation-exposed areas with limited human access as well as general waste areas where human access is undesirable, such as sewage treatment plants. Used for cleaning during downtimes or even when nuclear power plants are operating, the improvements in quality, health, safety and the environment (QHSE) are undeniable.
In the decommissioning of old nuclear power plants, the system is ideal for difficult work such as removal of accumulated sewage sludge and debris that could not be removed during the life of the nuclear power plant. Of course, this is just a sampling of the wide variety of industries which the SAKAL-system can make safer by eliminating personnel out of hazardous environments.


From the cabin, all movements of the robot are controlled by the operator. These can be followed on the HD screen via the onboard camera or via an external camera with an aerial view. The robot, which is connected to the vacuum truck, will enable large quantities of (liquid) substances to be processed in a short time and then be transported for decontamination and/or storage according to the customer’s procedures. Instead of a vacuum truck, an onboard submersible pump can also be used to circulate the water for cleaning, waste separation and return to the tank.


The KOKS SAKAL-robotic system can be fitted with various option kits that are appropiate for your needs and industrial applications.
