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
