Compressor Rack System
20% power saving
- Higher energy efficiency ratio(EER)
- Less defrosting, smaller motor input
- 42kg/m3 high density PU/PIR panels
Bitzer compressor rack uses multiple compressors in one system, bigger cooling capacity, safer, easier install and control. What’s more, each compressor is independent and run according to system loading, so higher efficiency and longer lifetime.
Danfoss oil balance system
Balanced oil level is very important for the compressor rack. If compressor no oil, it’ll damage soon.
High quality copper bending and welding
Specialized bend machine deal technology, 100% no leaking problem. In corners part, we use bending instead of copper corners.
Danfoss pressure controller
For compressor rack, each compressor run based on the machine loading, so accurate pressure controller is very important.
High quality control panels
It’s equipped with Schneider electric, with multi protections including phase protection, phase lack, over current, too constant starting of compressor, discharge temperature, etc.

Customer info: This project is in a tropical country, with ambient temperature up to +38C most of the year. Considered the machine stability and efficiency, we advise compressor rack systems.
Compressor rack: 4x18HP Bitzer semi-hermetic compressors, with EC fan, with economizer.
Cold room dimension 32x12x5meter with ante room, 150mm PU panels with 0.6mm color plate.
How to identify the original new Bitzer compressor?
If the Bitzer compressor price is 40% lower, it may probably not original new compressor. Also, each Bitzer compressor has one security code, you could check it on the Bitzer website.
Why compressor rack is better than a single compressor?
Compared to the single compressor, compressor rack is safer, more power-saving, easier maintaining and install. Price is a little higher than the single compressor, but for the long term considering, it is a very economical efficiency.
Which condenser type is better? Air cooled or water cooled?
If you could offer water with good quality and adequate supplies, water cooled condenser is a better choice; If not, air cooled condenser will be better.
How does each compressor work on the compressor rack?
Compressor rack works based on the cold room loading. If the low loading in the cold room, one compressor runs; when more loading is inside the cold room, two or three compressors run.
If one compressor was wrong, will it impact the working of other compressors?
No, as compressors can work independently, so one compressor wrong will not impact other compressor’s working.
What is the warranty for the refrigeration unit?
One-year warranty. But with the original new Bitzer/Copeland compressor, lifetime is 8~10 years at least.
