Description BITZER A/C Compressor 2GES-2Y-40S With its new BITZER ECOLINE series, BITZER offers high-efficiency universal compressors that satisfy the demands of modern refrigeration systems: extended range of applications energy efficient cost-effective power regulation wear-resistant drive mechanism quiet and low-vibration minimal space requirements robust BITZER ECOLINE compressors for operation with frequency inverters up to 70 Hz Depending on the refrigerant used and the environmental conditions, a compressor with a PW standard motor (400 V, 3-50 Hz) can be used, or a special motor (230V/400V, 3-50 Hz*) may be required and connected in a delta circuit (230 V, 3-50 Hz). The latter is the case for compressors using version 1 and 2 motors where they are to be operated throughout the entire documented area. The use of a PW standard motor for 400 V or the connection of a 230/400 V motor in a star circuit must be discussed with BITZER on an individual basis due to the drop in the torque value when operating above 50 Hz (fig 1) – see also Technical Information KT-420.
