Minimum Driveline Maintenance and Costs of Ownership
YZ driveline features a single moving assembly suspended in a magnetic field that does not require lubrication .
With fewer moving parts than traditional oil- or refrigerant-lubricated drivelines longevity is enhanced and maintenance is reduced .
The chart compares driveline maintenance ( assuming other scheduled maintenance tasks are equal across centrifugal chillers )
Magnetic bearings and lubrication free designs mean :
• No scheduled compressor / motor teardowns ; components are designed to last the life of the chiller
• No required filter changes
• No complex lubrication system maintenance
Initial Chiller Cost + Cumulative Driveline Maintenance Cost
125-150 % of initial chiller cost
110-120 % of initial chiller cost
< 10 % of initial chiller cost
