The new generation of oil-injected rotary screw compressors from Kaeser’s CSD series now delivers performance with even greater precision and efficiency. The integrated package consisting of motor, timing gears and airend permits the most energy-efficient airend speed to be selected for each operating point. The installed Electronic Thermal Management (ETM) and newly-designed inlet valve, together with the larger inlet filter, significantly enhance rotary screw compressor efficiency. The speed-controlled fan ensures further energy savings and a reduced CO2 footprint, since it only delivers as much cooling air as is actually required.
