  • Technical Information
Marine Condensing Unit

A marine refrigeration condensing unit typically is an assembly of a compressor, condenser, fan motor, controls and a mounting plate.  It has the function of a heat exchanger to cool down and condense the incoming refrigerant vapor into liquid, as well as a fan that blows outside air through the heat exchanger section to cool the refrigerant inside. Berg’s marine condensing units have various designs and come in a large cooling capacity range to fit your unique requirements.  

Features and benefits  

  • Custom engineered design 
  • Factory tested and certified  
  • Seawater cooled package available 
  • Minimal installation effort 
  • Limited floor space required
