Fluid Analysis Program - General
Quincy’s fluid analysis program is offered to all
customers using QuinSyn fluids in Quincy Compressor
®
Rotary Screw Compressors. This service provides
optimum drain intervals for compressors operating on
QuinSyn fluids. Monitoring of the total acid number
(TAN), barium level and/or viscosity throughout the life
of the fluid provides maximum protection to your
machine, while best utilizing the extended life features of
QuinSyn.
The fluid analysis provides historical information,
detailing items such as hours on the fluid, viscosity and
total acid number (TAN). Should results appear unusual
or suspicious, a detailed analysis can pinpoint specific
contaminants. A detailed report is furnished to you, your
Quincy Distributor and the Quincy Compressor
®
factory
upon completion of the fluid analysis.
Although QuinSyn fluids are rated by hours of life
expectancy under normal operating conditions, it is
recommended that fluid samples be taken every 500 to
2000 hours and sent to Quincy Compressor
®
Fluid
Analysis until a history of performance in a specific
compressor application is established. Once the
appropriate drain interval is established, the frequency of
the fluid 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.
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 fluid is left in the compressor
beyond its useful life, removing all of the spent fluid is
difficult. The oxidation products remaining can
considerably shorten the life of the new fill of QuinSyn
fluid.
