BITZER Scroll Compressors // ORBIT+
Implementation of high-efficient ORBIT+ Scroll compressors
/ Line Start Permanent Magnet Motor (LSPM)
 Significantly increased annual energy efficiency
 Permanent Magnet Motor can be used DOL
 Combines efficiency of a synchronous motor with robustness and easy use
of an asynchronous (AS) motor
 Lower current than standard AS motors
 Potential for smaller electric contactors
 Same dimensions, electrical connections as standard compressor

BITZER Scroll Compressors // ORBIT+
ORBIT+ with A2L Refrigerants
BITZER solution answering to ECO
design directive and F-GAS regulation
/ Cooling Capacity
 Compensation of cooling capacity
losses with the LSPM motor
/ SEER Efficiency
 LSPM motor + R454B = significant
increase of SEER

BITZER Scroll Compressors // ORBIT+
/ ORBIT+ compressors approved for R410A and alternative low-GWP
A2L refrigerants (R454B, R452B, R32), with CE marking
 PED approval for Fluid Group 1 and Fluid group 2 refrigerants
/ Performance tests with GSU6/GSU8 and R410A/R454B/R452B
 Performance coefficients available
 Current status on R410A:
 5-8% increase in SEER efficiency, 3-5% increase in cooling capacity
/ R454B (XL41, GWP: 466, A2L, Temp. glide ~1.5K), preferred in EU
 Average 3% higher COP and 3% less cooling capacity than R410A
 R32 (GWP: 675, A2L) shows much higher DGT and lower efficiency
