Maintenance Considerations
notes Regularly logging oil and refrigerant charges, and examining the trends of this
data, can help identify potential problems before they occur.
An oil analysis is a key preventive maintenance measure and should be
conducted at least annually. It will help the compressor last longer while
maintaining chiller efficiency and reducing refrigerant emissions.
A certified chemical laboratory can be contracted to perform the analysis for all
types of compressors. Often the chiller manufacturer can provide this service.
Oil Analysis
▲Why perform regular oil analysis?
◆Helps reduce maintenance costs
◆Detects problems without
compressor disassembly
◆Extends service life of oil charge
◆Reduces environmental problems
related to oil disposal
◆Helps maintain compressor
efficiency and reliability
◆Helps lower refrigerant emissions
