Task
Securing operational availability of machines and equipment for ventilation and air-conditioning for the main administrative building of a insurance company by employ-ment of a round-the-clock condition monitoring systems providing the precondition for the planning of maintenance processes.
Preparation
Since 1998 the management of WWK Insurance Group has been located in a modern administrative complex in the Mars street 37 in Munich. It comprises 16.300 m2. About 1.200 employees work there. A centralized air-conditioning and ventilation system constitutes the core aggregate of the facility. It provides for room conditioning throughout the administrative centre. The air-ventilation machines essentially consist of 2 supply-air axial-flow fans each providing an output of 140 KW and an air supply of 300.000 m3/h and 2 exhaust-air axial-flow fans each providing an output of 76 KW and an air-outflow of 160.000 m3/h. A complete standstill of the ventilation system, which came with a total machine damage, had in the past created havoc, even though the initially unidentified damage had been marginal. Necessary spare parts procurement and elaborate repairs of ventilation equipment had taken 6 months. This experience prompted WWK to look for a remedy to the problem, particularly for monitoring vibrations and bearings of the respective ventilation machines. After examination of the job profile by a team from Prüftechnik Condition Monitoring GmbH, WWK was submitted a proposal how to implement the necessary measures.
