Maintenance Considerations
Refrigerant analysis measures contamination levels and determines suitability
for continued use. It can also determine the acceptability of recycled refrigerant
for reuse. Refrigerant analysis helps extend the life of the existing charge and
ensures that the chiller is operating at peak efficiency.
Logging the 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
improving chiller efficiency and reducing refrigerant emissions. A certified
chemical laboratory has years of experience in analyzing oil and refrigerant
from all types of compressors.
Often the chiller manufacturer can provide this service.

Fluid Analysis
▲ Why perform regular oil analyses?
◆ 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
