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.

Erläuterungen
- Toleranz (±10%) bezogen auf Mittelwert des Spannungsbereichs. Andere Spannungen und Stromarten auf Anfrage
Daten bezogen auf 400 V/3/50 Hz bei direktem Netzbetrieb. Für die Auslegung von Schützen, Zuleitungen und Sicherungen max. Betriebsstrom / max. Leistungsaufnahme berücksichtigen. Schütze: Gebrauchskategorie AC3. Überstromrelais zur Absicherung des max. Betriebsstroms einsetzen.
PW: Motor für Teilwicklungsanlauf (Part Winding) Y/YY
- 4VES-6Y .. 6FE-50Y Wicklungsteilung 50%/50%
- 8GE-50Y .. 8FE-70Y Δ/ΔΔ Wicklungsteilung 60%/40%
- Für PW-Anlauf Motorschütze auf ca. 60% des max. Betriebsstroms auslegen.
- Ausführung für Y/Δ auf Anfrage
Daten für die Auslegung des Frequenzumrichters (FU) – Motorversion 3 (R134a Verdichter): bezogen auf 400 V/3/50 Hz Netzspannung und Einsatz des 400 V/3/50 Hz Standardmotors für FU-Betrieb bis 70 Hz. FU mit Motorversion 1 und 2: Betrieb im gesamten Anwendungsbereich oberhalb 50 Hz erfordert Motor mit Sonderspannung.
