Periodically we organise technical trainings aimed to promote the screw compressor’s technical knowledge and its ordinary maintenance. The trainings, lasting a day, are divided into a theoretical part which is done in classroom and a practical part which is done in a dedicated area of REFPOWER’s workshop. At the end of the day, the participants will have acquired the needed knowledge for a first diagnosis about a screw compressor’s failure causes in a plant, for the direct solution of a broad spectrum of problems and for performing the ordinary maintenance of the compressor itself.
