Screw CompressorReciprocating Compressor
ProsPros
Ideal for multiple ice makers driven off a compressor and where operators may not be presentIdeal for single ice maker operation on a single compressor with high load variability. Works well for constant loads, such as flake ice makers
Very efficient when operating at 85% or more loadedBelow 100% capacity, reciprocating compressors use less power than similarly-sized screw compressors
Better suited for base loading and operation at full load and never needs to be unloaded completely – Infinite unloading levels but will shut down if fully unloadedUnloads 100% with no efficiency loss. Unloads in increments (75%, 50%, 25% unloading for example)
Requires less maintenanceSimple to maintain and rebuild
Two 75-ton Vogt ice makers only require one screw compressor saving approximately 30% on the compressor purchase 
ConsCons
Less efficient at below 50% capacityRequires more maintenance
Difficult to run on just one machine
