The SC 90A is a single nozzle tank cleaning machine especially developed of sector cleaning tanks/cisterns/vessels in hazardous ATEX classified areas. It gives the user a possibility to optimize the cleaning, with minimal use of time, energy and cleaning media.

SC 90A consists of two main parts; one washing unit that is fixed installed in the tank and one portable air driven drive unit SC 150 for operation. The drive units can be exchanged or removed without exposing the tank to the outside atmosphere. It is the product of choice when long jet-lenghts and/or a high level of jet impact is required.
