    AC/DC rotating machinery diagnostics

    After each complete repair, we conduct standard acceptance tests on the machinery, including strength test of the insulation system, diagnostic tests of bearing units and vibration measurement. The data obtained is stored in our archives along with the technological documentation.

    In order to reduce the risk of failure, we offer regular maintenance and inspections under preventive diagnostics. These are conducted by experienced personnel holding appropriate permissions with the use of vibro-acoustic diagnostic equipment and thermal imaging. Inspections are carried out in accordance with a schedule developed and agreed with the Client or based on provisions set out in the contract. Duly and regularly carried out on-site machinery inspections allow to avoid costly failures and production downtime. On the basis of data obtained during inspections of machinery in operation, we are required to provide the Client with the possibility to upgrade or replace equipment if required.

    We also perform inspections and repairs of machinery installed in gas hazardous areas in the chemical industry, mining industry and others.
