This document discusses Turbo Oil-Free Compressors for chillers. It notes that magnetic bearings allow for extremely high speeds of up to 200 m/s without lubrication. This results in reliable, low maintenance systems with high efficiency. Applications include replacing old centrifugal chillers or adding backup chillers. The compressors come in a range of sizes from 265-1055 KWc and can be used for both water-cooled and air-cooled systems. Installation involves removing an old compressor and installing the new one along with any necessary piping or electrical work.
