Refrigeration Compressor (Screw) · Refrigeration
GEA Refrigeration Marine Bock HG 500kW R404A Marine is identified in the source list as a refrigeration compressor (screw). It is installed in a refrigeration machinery room or machinery space as part of a provision, cargo, HVAC or process refrigeration circuit. Its purpose is to provide or support refrigeration by compressing refrigerant vapor or operating the provision-cooling plant identified by the category. The source record provides no additional model-specific operating figure beyond the listed designation and category. The exact compressor architecture, refrigerant compatibility, evaporator and condenser arrangement and capacity-control method are model-specific. The exact model designation distinguishes displacement, refrigerant compatibility and capacity-control arrangement from neighboring refrigeration equipment; refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Monitor suction and discharge conditions, oil level, oil pressure where applicable, temperatures, vibration and compressor loading. Check for refrigerant and oil leakage and verify oil-management equipment operates as designed. Inspect couplings, filters, strainers and capacity-control mechanisms where fitted. Investigate any evidence of liquid return or repeated protective trips before restarting. Maintain system cleanliness and use only refrigerant and lubricant approved for the installed design. Refer to the manufacturer documentation for the exact figure for operating limits, clearances and overhaul procedures.
Keep model-correct seals, gaskets, oil filters or strainers, approved lubricant and manufacturer-recommended valve, bearing or capacity-control service parts. Critical cargo or provision refrigeration may justify additional compressor-specific wear parts. Confirm refrigerant compatibility and exact parts from manufacturer documentation.
