The new DSD series of rotary screw compressors (photo) is now available for flowrates from 14 to 25 m³/min. Featuring new airends with high-efficiency Sigma Profile rotors and IE4 motors, they deliver improved specific power of up to 9%, as well as up to 6% higher flowrates than previous models, says the company. These improvements, together with other enhancements, result in significantly reduced energy costs. For example, the new IE4 motor is said to be the most efficient currently available, which enables peripheral losses in compressed-air production to be reduced even further. Moreover, the Electronic Thermo Management (ETM) system regulates oil temperature to ensure a safe and consistent differential from the dewpoint temperature. This strategy also prevents unnecessarily high airend discharge temperatures and provides additional energy savings. — Kaeser Kompressoren SE, Coburg, Germany
