Non-man entry cleaning robots for the refineries and tank farms

Refineries & Tank terminals

A refinery (in this case oil or petroleum) is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha.


Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units, such as distillation columns. In many ways, oil refineries use much of the technology, and can be thought of, as types of chemical plants.


An oil terminal (also known as tank farm or oil depot) is an industrial facility for the storage of oil, petroleum and petrochemical products, and from which these products are transported to end users or other storage facilities. An oil terminal typically has a variety of above or below ground tank storages.

Robots for refineries & tank terminals



ATEX Zone 0 robot

The KOKS ADES EX-robot is designed to operate within ATEX zone 0 environments. The ADES EX-robot is intended for cleaning aboveground, underground storage tanks and for cleaning water basins, sewers or other confined spaces.



ATEX Zone 0 robot

The KOKS ADEX-robot is designed to operate within ATEX zone 0 environments. The ADEX-robot is intended for cleaning aboveground oil storage tanks, oil sludge pits and for cleaning hazardous substances in potential confined spaces.

What are the types of dangers in the refineries & terminals for industrial cleaners?

The foremost danger on each oil & petroleum refinery and/or terminal are the gases of the products processed or stored. These gasses are often subjected to being explosive or poisonous. The first is in the European directives referred to as ATEX classified zones. The amount of risk determines whether the ATEX zones for gas or mist explosive risk are indicated with ATEX zone 0, 1 or 2.

Where to utilize a robot in the refineries & terminals industry?

The majority of the work where the robot is already utilized on refineries and tank terminals is to clean out the sediment of the tanks. This can be for periodically recertification of the tank or due to changing the product which is in the tank and avoid a chemical reaction. The robot is designed to enter through the 24 ‘’ / 600 mm manhole in order to start the cleaning procedure normally done by manual labour.  The robot teams up with an ADR certified vacuum truck to ensure a safe working environment for the small team in charge for cleaning the tank.
