STAR-717 is specifically designed for use in Ammonia Refrigeration
Systems. Designed to meet and exceed all OEM specifications,
STAR-717 provides reduced oil consumption, excellent cold
temperature operations and a very long fluid life.
STAR-717 is ideal for use in ammonia compressors because of its
ext5remely low oil carryover rate; as much as 50-80% less than
competitive fluids. This is due to STAR-717's extremely low
volatile and very low solubility with ammonia.
When developing STAR-717, our formulators took the naturally high
viscosity index and low pour points of 2-stage hydrocracked base
fluids and boosted it with ArcticFlow, PetroBrand's own proprietary
blend of additives that dramatically enhances STAR-717's cold
temperature fluidity. The end result is a lubricant that remains
fluid at very low temperatures, and is thus far less likely to coat
the evaporator, and is easier to purge from the system.
STAR-717 is a highly thermally stable formulation that offers
exceptional resistance against oxidation, as well as carbon,
varnish and sludge formation. All of which translates into a
exceptionally long fluid life
