Service Department of JSC KYIVENERGOMASH is engaged in servicing and maintenance of the equipment of heat engineering facilities and installations. Service and maintenance specialists have been trained by manufacturers of boiler equipment, they take regular training courses in order to improve their attainments and knowledge. The Service Department has service motorcars equipped with necessary implements, tools, materials and spare parts for the serviced equipment. As heating season begins, the Service Department shifts to a round-the-clock operation. The operation of boiler plants is monitored on-line by a dispatcher owing to the system of supervisory control based on Viessmann boilers. In case of any failure or malfunction in the boiler plant's operation, the dispatcher identifies the cause of faults using Vitosoft and Vitodata software systems and, if it is impossible to remove the faults remotely, contacts the line service engineer to report the event. A team being informed about the detected fault (which enables a prompt removal of faults in the system operation) is sent to the spot.
