2 General description
2.1 Introduction GA 55 + up to GA 90 are single-stage, oil-injected screw compressors driven by an electric motor. The compressors are available in air-cooled and water-cooled version.
The compressors are controlled by an Elektronikon ® controller.
GA Workplace
GA Workplace compressors are enclosed in a sound-insulated bodywork. The Elektronikon control module is fitted to the panel on the right hand side. An electric cabinet comprising the motor starter is located behind this panel. A condensate trap with Electronic Water Drain (EWD) is provided.
