This reverse integration strengthens Grillo’s leading market position. Since taking over of operations in 2007, Grillo has been producing DMS in Frankfurt, with until now externally produced DME. Moreover, around 100 out of total 500 process automation devices being installed by Gesat are from ABB, amongst them TTH300 and TTF300 temperature sensors, S2XX-HN1S membrane pressure sensors and Triowirl flow-meters.ĭME serves as raw substance for the production of dimethyl sulfate (DMS), which is used for the production of bio-degradable fabric softener or colorants. The supply also included additional licenses and numerous redundancy–link-modules RLM 01, in order to make the profibus PA consistently redundant. In close coordination with ABB at the site, Gesat has updated Freelance to version 9.2 with redundant controllers AC 800F and Profibus. According to Grillo, the expanded plant is the most modern and energy-efficient DME production plant in Europe. Since end 2012, the chemicals company Grillo-Werke AG located in ‘Industriepark Hoechst’ has been concentrating on the in-house production of dimethyl ether (DME).
