Tandem compressors are the simplest type of parallel compressor system using two compressors
Exceptionally effective performance scaling can be achieved by turning a single compressor on and off. The 4 and 6 cylinders models can also be fitted with power regulators (cylinder shut-off) to allow operation with up to four or six performance levels. Affordable and energy-efficient full and partial load operation is possible using all conventional refrigerants, especially in applications with widely varying loads.
ECOLINE models
This series of tandem compressors use 2-6 cylinder BITZER semi-hermetic compressors, opening a new dimension for simple and compact parallel systems. This is in addition to the usual features of semi-hermetic compressors.
For further information regarding the technical design of the compressors, see single compressors.
Performance data
All values are based on European norm EN 12900 and 50 Hz operation. The evaporation and condensation temperatures refer to dew point values (saturation conditions).
All data is without fluid super-cooling. Based on EN 12900 this data contains significantly different values compared to data acquired from using a 5 or 8.3 K super-cooler.
See refrigerant report (A-500) for explanations.
Power consumption and usage limitations
See KP-104 and BITZER software. Usage limitations are the same as for a single compressor.

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.
Tolerance (±10%) based on the mean voltage range. Other voltages and current types on request
220-240 V Δ/3Ph/50 Hz - 380-420 V Y/3Ph/50 Hz
265-290 V Δ/3Ph/60 Hz - 440-480 V Y/3Ph/60 Hz
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.
Part winding motor Y/YY. Wind distribution 50%/50%. Y/ design on request
