GENERAL DESCRIPTION
The SELCO SF-300 Series are a family of fully
synthetic industrial lubricants developed
specifically for refrigeration compressor.
They are especially formulated, synthesized
hydrocarbon lubricants for severe service
under conditions that are beyond the capabilities
of conventional mineral oils. In addition,
they improve the performance and efficiency
of standard refrigeration system compared
to conventional mineral oils.
These four grades have very low pour points,
Zero wax content, a high natural viscosity
index and thermal stability. They exhibit
greater chemical stability in the presence
of refrigerants and other systems components,
and have a low volatility. Their low solubility
makes them suitable for systems using refrigerants
such as R12, R114, and ammonia.
APPLICATION
SELCO SF-300 Series are fully miscible
with conventional mineral oils. If inadvertently
mixed with mineral oils, there will be some
loss in the superior performance properties
of the synthetic lubricant. The lubricant
however, can be continued in service until
it becomes convenient of change the system,
