compressors with 2 capacity stages each or
•
4
*1
compressors with 3 capacity stages each or
•
12
*2
individual compressors without capacity regulation
•
*1 When using speed-controlled compressors with base load rotation or a spray system, the maximum
number of compressors is reduced by one compressor.
•
*2 When using speed-controlled compressors with base load rotation, the maximum number of
compressors is reduced by one compressor and reduced by two compressors when using a spray
system.
*1: When using speed-controlled compressors with base load rotation or a spray system, the maximum
