• 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
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.

Note 2: 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
Note 3: 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
