Outstanding advantages As specially designed compressors for use on combat vessels, supply ships or submarines, the 5000 series offers you the specific advantages of future-proof compressor technology, extremely high reliability, as well as the lowest lifetime costs and structure-borne noise emissions on the market. Fit-for-the-future compressor technology Developed in the early 1990s after in-depth analysis of the improvement potential for existing compressors Designed with the future in mind, e.g. low maintenance requirements and low structure-borne noise Nothing but state-of-the-art technology to minimize the risk of obsolescence in the next 50 years Tested and certified to all US Mil, UK NES and German BV standards, for example Maximum reliability CW circuit designed for direct seawater cooling (50 bar) providing high safety margins even when using freshwater Dry liners for all compressors stages to avoid internal leakage Hermetic separation of oil, water and air spaces No internal piping Floating cooler stack to avoid heat stress Lowest lifetime costs Valve check/change completed in just 5 minutes Withdrawable cooler inserts with straight tubes for easy cleaning Compressor embarkable through 800 mm passageway No major overhaul required if scheduled maintenance tasks are carried out All maintenance tasks performable by on-board personnel Lowest structure-borne noise emissions Full balancing of free inertial forces and moments thanks to vertical star arrangement of cylinders/pistons Dynamic balancing and weight calibration of running gear during production process Residual free forces in radial direction easy to attenuate Values below mounts in the range of double resilient mounting
