Section VI - Compressor Fluids
Fluid Analysis Program - General
Quincy’s fl uid analysis program is offered
to all customers using QuinSyn fl uids
in Quincy Compressor
®
Rotary Screw
Compressors. This service provides
optimum drain intervals for compressors
operating on QuinSyn fl uids. Monitoring of
the total acid number (TAN), barium level
and/or viscosity throughout the life of the
fl uid provides maximum protection to your
machine, while best utilizing the extended
life features of QuinSyn.
The fl uid analysis provides historical
information, detailing items such as
hours on the fl uid, viscosity and total acid
number (TAN). Should results appear
unusual or suspicious, a detailed analysis
can pinpoint specifi c contaminants. A
detailed report is furnished to you,
your Quincy Distributor and the Quincy
Compressor
®
factory upon completion of
the fl uid analysis.
Although QuinSyn fl uids are rated by hours
of life expectancy under normal operating
conditions, it is recommended that fl uid
samples be taken every 500 to 2000 hours
and sent to Quincy Compressor
®
Fluid
Analysis until a history of performance
in a specifi c compressor application is
established. Once the appropriate drain
interval is established, the frequency of
the fl uid analysis can be reduced unless
operating conditions change.
NOTICE!
All Quincy Compressor
®
extended
airend warranty programs require
that fluid samples be sent to Quincy
Compressor
®
Fluid Analysis a minimum
of every 2,000 hours or every 6 month
for light use units.
The depletion of antioxidants, change of
viscosity, barium and acid levels all occur
with time. It is extremely important to
change QuinSyn before the antioxidants
are completely depleted. If the fl uid is left
in the compressor beyond its useful life,
removing all of the spent fl uid is diffi cult.
The oxidation products remaining can
considerably shorten the life of the new fi ll
of QuinSyn fl uid.
