Introducing Kaeser's redesigned ESD rotary screw compressor series. Available in 250 and 300 hp models, ESD units provide flows from 816-1522 cfm and pressures to 217 psig.   The ESD series was redesigned for increased efficiency and improved specific performance, as the one-to-one direct drive design includes a premium efficiency drive motor with three PT 100 temperature sensors. All models come standard with the new Sigma Control 2 intelligent compressor control for enhanced communications capabilities and equipment protection. Also standard is a variable speed fan for the fluid cooler that helps save energy by adjusting to cooling demands. Maintenance points are more easily accessible than ever before with five access doors and a removable panel.
