For many years, Dovianus (NL), Total (FR), and Tecnicas Reunidas (ES) are loyal partners in the field of advanced engineering and technological solutions. The Total OPTARA project once again is chosen for Dopak sampling systems. The project consists of the following Dopak series: DPM, S23, DPJ, S32-G, and S32-LG samplers. The goal of OPTARA is to transform an existing unit and to build a new unit at the Total refinery in Antwerp (BE), to adapt to the needs of the market.
