Who Should Choose the AC and Refrigeration Package? 

  Electro-Technical Officers (ETOs) –who need a complete understanding of refrigeration and air-conditioning systems, including control logic, electrical protections, safeties, and systematic troubleshooting

  Junior Engineers (JE) – who want to build strong fundamentals of refrigeration principles, system layouts, and normal operating parameters used onboard ships

   4th Engineers (4/E) – who aim to develop a solid understanding of compressors, condensers, evaporators, expansion devices, and routine system operation

   3rd Engineers (3/E) – who want to confidently read system diagrams, identify common faults, and support troubleshooting as responsibilities increase

   2/E & C/E – who are responsible for maintenance, system reliability, safety devices, efficiency, and advanced troubleshooting of refrigeration and air-conditioning plants
