PRODUCT ADVANTAGE
- Ideal for -18℃ cold room, excellent efficiency.
- Equip with Copeland ZSI scroll compressors with CoreSense module, which is supplied as a standard together with the compressor. This controls the amount of liquid injection by measuring the discharge temperature through an electronic sensor mounted on the discharge line. With the CoreSense built-in program, it automatically calculates the EXV's opening and commands it to inject the optimized amount of liquid refrigerant into the compressor. LED display alerts user of DLT sensor status and EXV operation enabling easier troubleshooting.
- Wide range operating envelope, from -30℃ to 0℃ evaporating temperature
- Scroll compressors have 70% fewer moving parts than reciprocating compressors. Their axial and radial compliance enhances liquid handling, while the hermetic design minimizes leakage risks.
- Equip with selected refrigeration parts to achieve the stable system operation.
- Low sound and vibration leading to quieter operation.
