COMPETENCE FOR GENERATORS OF UP TO 500 MW: EMIS has made long-term investments and acquired the professional competency for the service of generators. The well-balanced spectrum of services offered in this field covers the disassembly, the diagnosis, the inspection, the re-assembly and the (re-) commissioning. It also includes measurements for the commissioning, calculations on the expected service life and the use of the most sophisticated equipment, such as our unique end-bell removal device.

ALL SERVICES AT A GLANCE:
