The SC 90A is a single-nozzle tank cleaning machine especially developed for sector cleaning of tanks/cisterns/vessels in hazardous ATEX classified areas. It allows the user to focus the cleaning effort where needed, thus helping to optimise the cleaning process with minimal use of time, energy and cleaning media.

The SC 90A consists of two main parts:  the wash unit which is fixed in the tank, and the air-driven drive unit SC 150 which is portable. The drive units can be removed and swapped without removing the wash unit or otherwise exposing the tank to the outside atmosphere.

The SC 90A is the product of choice where long jet length and/or a high level of jet impact is required.

Quality Control, Compliances & Certifications
The SC 90A is produced in accordance with ISO 9001 Quality Standards and our certificate of conformity and accreditation is available on request. Additionally, the SC 90A conforms to United States ASME standards for construction, and to European, CE and ATEX standards for design, construction and safety.
