First screw units that were packaged by EGS were for this Romgaz project. After winning the tender EGS started packing four Sullair DC2512 and three Sullair DC2517 screw compressors, each driven by a Caterpillar CG137-8 engine. Every unit had to be placed inside an enclosure with lightning protection. Robust walls can handle sever weather conditions and will allow access for maintenance and repair works.
