The KOKS SAKAL-robot was originally designed for handling and removal of pollution from hazardous and contaminated storage and drain tanks in non-ATEX zones at the site of nuclear power plants, where human access is necessarily restricted due to the radiation levels present. Nowadays the SAKAL-robot is designed for more applications such as cleaning wastewater systems, sewers, drainage pools, industrial tanks and ponds in non-ATEX zones at for example copper, aluminum and zinc plants. The SAKAL-robot is designed for long-term use under severe conditions in tanks and various other types of confined spaces in submerged conditions.


In addition, the KOKS SAKAL-robot is a proven design for heavy and hazardous industrial applications and suitable for cleaning areas such as underground tanks or collection basins in non-ATEX zones with restricted human access.

The KOKS SAKAL-robot enables its user to clean in non-ATEX zones at environments where human access is undesirable. The undesirable situations can be cleaning of contaminated storage and drain tanks, wastewater basins filled with accumulated sewage sludge and debris, cleaning at sewage treatment plants and cleaning tanks or drainage pools at industrial plants filled with contaminated liquids or sludges.
The advantages for health, safety and the environment, as well as an improvement of the cleaning quality, are undeniable. Of course, this is just sampling of the wide variety of industries which the SAKAL-robot can make safer by eliminating personnel out of hazardous environments.


The SAKAL-robot can be controlled by the operator with both a standalone power pack (SAPP and SAPP Pro) as well as a transportable, ventilated cabin (TVC). Furthermore, it is available in a built-in version such as a van or trailer.
Application of different types of suction heads with its own electric submersible pump makes this SAKAL-robot very versatile and efficient. The user benefits from significant time savings and a huge reduction in cost.
