The SL series is a range of single-stage centrifugal turbo compressors with a semi-open impeller (3D design) mounted between the bearings. The SL series is designed to meet the most demanding duties in coke oven gas applications, especially to handle rotor unbalances caused by the sticky cokery gases. Its design features, such as the gas inlet and outlet facing downwards, the self-cleaning, semi-open impeller and the rotor turn drive, enable this compressor to handle the built-up of tar from the coke oven gas. Consequently, the SL series serves the most demanding duties in cokeries all over the world and provides top class safety and reliability at low lifecycle costs to their owners.
Gas ﬂows up to 400,000 m³/h can be handled.
