BITZER ECOLINE compressors for operation with frequency inverters up to 70 Hz
All BITZER ECOLINE compressors are designed and optimised for 70 Hz operation. 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.
* Compressors 2KES-05Y to 4BES-9Y are fitted with 230/400 V, 3-50 Hz motors as standard and can be operated in either a 400 V star circuit configuration or at 230 V in a delta circuit.

Technical data
Notes
- Data for 400 V/3/50 Hz with direct mains power supply. Observe the max. operation current / max. power input when selecting contactors, leads and fuses. Contactors: Category AC3. Use overcurrent relay to avoid exceeding max. operating current.
PW: Part winding motor Y/YY
- 4VES-6Y .. 6FE-50Y wind distribution 50%/50%
- 8GE-50Y .. 8FE-70Y Δ/ΔΔ wind distribution 60%/40%
- Use motor contactors rated to about 60% of the max. operating current for PW start up.
- Y/Δ design on request
380-420V PW YY-3Ph-50Hz
440-480V PW YY-3Ph-60Hz
Data for integration of the frequency converter (FC) – motor version 3 (R134a compressor): based on 400 V/3/50 Hz mains supply and use of 400 V/3/50 standard motor for FC operation up to 70 Hz. FC motor versions 1 and 2: Operation above 50 Hz anywhere within the operating area requires a special voltage motor.
