QuinSyn PG
Effective on orders entered on June 1, 2000 and later,
Quincy’s factory fill fluid changed from QuinSyn
to QuinSyn PG.
Orders placed prior to June 1, 2000
shipped with QuinSyn.
QuinSyn PG is a custom blended polyalklene glycol/ester
(PAG). QuinSyn PG is an ISO 46 viscosity fluid with an
8,000 hour life under normal operating conditions (exact
fluid life is determined by the fluid sampling program)
and is the chosen fluid for Quincy’s new five-year airend
warranty effective June 1, 2000 (see Blue Alert #566).
Under extended warranty conditions QuinSyn PG fluid
life is rated at 8,000 hours or one year, whichever occurs
first.

Applications
QuinSyn PG is the recommended fluid in high humidity
applications due to its ability to hold water. QuinSyn PG
is best suited for applications where high humidity exists
and the machine cannot be shut down to drain water from
the reservoir.
Disposal
QuinSyn PG is considered nonhazardous waste. Disposal
of this fluid should be done in accordance with Local,
State, and Federal regulations. Separation of this fluid
from condensate will require those separators designed to
handle fluid emulsions. The QIOWA fluid/water separa
-
tor is suitable for separation of fluid emulsions such as
QuinSyn PG. Please contact Quincy’s Service Depart
-
ment for more details.
Fluid Analysis Program
The fluid sampling for QuinSyn PG has been extended to
2,000 hours because of the superior quality and forgiving
nature of this fluid. The new five-year extended war
-
ranty with QuinSyn PG requires 2,000 hour sampling as a
condition of maintaining the warranty.
NOTICE!
To maintain warranty compliance, fluid samples
of QuinSyn PG must be sent to Quincy Compres-
sor Fluid Analysis a minimum of every 2,000
hours.
Because this fluid differs from QuinSyn, different meth
-
ods are employed to evaluate the fluid in the sampling
program. Primary concerns with this fluid are the total
acid number (TAN) and barium levels. QuinSyn PG will
not be condemned on water percentage nor antioxidants
but will be condemned on low barium and high TAN
values. The barium in the fluid acts as a corrosion inhibi
-
tor, therefore we have set low limits for this additive (see
page 42 for limits).
