BOG (Boil-Off Gas) compressors are designed to compress vaporized LNG that naturally occurs during storage and/or transportation. By routing the gas to combustion or reliquefaction processes, these systems help recover energy and minimize emissions.

Key Features

NS's BOG compressor is a high-speed centrifugal model equipped with foil gas bearings. Its oil-free design eliminates the need for oil tanks and filters, simplifying maintenance and reducing system size. A fully sealed configuration ensures complete gas containment and zero external leakage.
