Since it was established in 1978, IGT's Design Engineering Services (DES) group has been involved in the mechanical design, instrumentation and control, and construction of energy systems ranging in size from laboratory and bench scale through process-development unit (PDU) and pilot-scale facilities. The staff of engineers, which covers a variety of disciplines, is experienced in all areas of process design, plant construction and start-up, economic feasibility analyses, and project management activity.
