GEA compressors fulfill the high maritime demands for many years already. They help to provide a comfortable climate in cabins, keep provisions cooled and are additionally used in many other applications. GEA compressors also work reliably on container ships, passenger ships or fishing boats.

High efficiency does not need to come at the expense of durability, as GEA proves with the piston compressors of the semi-hermetic series GEA Bock HG44e and GEA Bock F16.

The F-series includes open, single-stage compressors with 2, 4 or 6 cylinders that are designed for common synthetic refrigerants (e.g. R134a, R404A, R507, R407C, R22). The maximum displacement volumes are 12,6 to 214,1 m³/h (1.740 1/min). They are optionally driven directly via a coupling or with a V-belt. Due to the high-volume oil sump as well as the reliable oil pump independent of rotating direction, the use in a wide speed range is possible. A stable drive, the successful mass compensation and the low pulsation contributes to the robustness and calm operation. The F-series runs without any problems even at short-term inclinations of up to 30° in both axes, making it perfect for marine use.

The semi-hermetic piston compressors HG44e represent a broadly set-up series of suction gas cooled compressors with maximum displacement volumes from about 6,5 to 337,5 m³/h (at 60 Hz). Therefore the series cover the whole refrigeration and air conditioning requirements on ships, from cabin cooling to provision cooling. The optimized semi-hermetic compressors benefit from a cutting-edge valve plate system, highly efficient electrical motors and an improved gas flow as compared to the predecessors.
