i worked on case cade but the compressor was not screw type
at this time what u have study about this systme. and how you will design condencer and evaporator
Are you sure about the capacity?
It too high for -70°C. Usually cascade systems are very small.
Also, you have to ask the screw manufacturer to see if their compressor can run with R23.
Again, your capacity is way too high.
