FAQ
1. Why is a compressor rack better than a single compressor?
2. Which condenser type is better? Air-cooled or water-cooled?
If you have access to good quality water and sufficient supply, a water-cooled condenser is a better choice. Otherwise, an air-cooled condenser would be more suitable.
3. How do the compressors work on the compressor rack?
The compressor rack operates based on the cooling load of the cold room. When the load is low, one compressor runs; when the load increases, two or three compressors operate simultaneously.
4. If one compressor fails, will it affect the others?
One year warranty. However, with original Bitzer/Copeland compressors, the lifespan is at least 8–10 years.

Double Screw Parallel Refrigeration Compressor Unit
Company Brief
Features of the Compressor Racks
Compared to a single compressor, a compressor rack is safer, more energy-efficient, easier to maintain and install. While the initial cost may be slightly higher, it offers greater long-term economic efficiency.
No, since each compressor operates independently, a failure in one will not impact the others.
