Oil-free centrifugal chillers have been on the market for more than a decade. Some chilled water plants have these chillers installed alongside other conventional oil-lubricated centrifugal chillers, while other installations use only oil-free centrifugal chillers. During that time, manufacturers, owners and operators have accumulated experience regarding maintenance practices, performance trend logs, service records and reliability. This session shares lessons learned and best practices by comparing and contrasting operating and maintenance issues of conventional and oil-free centrifugal chillers.
