Kaeser Compressors, Inc. Twin Rotary Screw Compressor with Direct Drive HSD Series

Model: HSD Series Horsepower: 500-700 hp Capacities: 1653 to 3044 cfm Standard Pressures: 80 to 217 psig (specific pressure range dependent on model and package chosen) Two Compressors, One Cabinet Each HSD incorporates two individual compressor units including a motor, Sigma Profile airend, separator, aftercooler, drain trap, and filtration. Since each module is a complete compressor – and not just two airends stacked together – the HSD provides maximum part-load efficiency, built-in redundancy, and reduced installation costs. Optimum Efficiency The HSD's Sigma Control units are able to precisely match each compressor's performance to meet the current compressed air demand - providing significant energy savings and optimum efficiency. Sigma Control System Each of the HSD's two self-contained compressor units are controlled by their own industrial PC-based Sigma Control controller. Operational status can be quickly identified with plain text displays and simple LED indicators.
