About Us

A1 Duó Kft. has been providing professional internal cleaning services for road tanker vehicles, tank trucks and IBC containers since 2005. Thanks to our nearly two decades of experience, we are now one of Hungary’s largest and most professionally equipped tank cleaning stations, serving domestic and international transport companies, as well as chemical and food industry businesses.

Our service goes far beyond traditional tank washing. Each cleaning process is adapted to the properties of the previous cargo and the requirements of the next transported product. This is particularly important for materials where even the smallest contamination can pose a significant quality or safety risk.

At our facility, we regularly clean tanks used for transporting chemical raw materials, resins, adhesives, isocyanates, toxic substances classified as ADR Class 6.1, as well as food industry products. Cargoes with different characteristics require specialised technologies, extensive professional experience and strictly controlled work processes.

Our company operates according to ISO 9001 and ISO 14001 management systems, complies with EFTCO requirements and is authorised to issue EFTCO Cleaning Documents (ECD). The ECD is an internationally recognised certificate confirming that tank cleaning has been carried out in accordance with European professional standards.

As an ADR-certified cleaning station, we also perform the cleaning of tanks transporting dangerous goods in full compliance with regulations, while maintaining the highest standards of environmental protection and occupational safety.

During our work, our primary goal is to ensure that our partners’ vehicles are safely, verifiably and fully prepared to receive the next cargo after cleaning. Thanks to this, our customers can rely on fast, reliable and high-quality professional service over the long term.

A1 Duó Kft. is a member of the Hungarian Association of Tank Cleaners and is committed to continuous technological development, sustainable operations and meeting international quality requirements.
