Nu-Calgon RL32-3MAF Polyolester Refrigeration Oil, Gallon.
The requirements of today's refrigeration and air
conditioning compressor lubricants are complex.
They must be compatible and miscible with the HFC
refrigerants, and they must be compatible and miscible with
CFC's and HCFC's as well as mineral and alkylbenzene oils.
Polyol ester lubricants meet these needs, and the EMKARATE
RL line is the preferred choice. Working in close
collaboration with compressor and system manufacturers,
these OEM-approved POE lubricants cover a wide viscosity
range from 7 cSt (35-40 SUS) to 220 cSt (1100 SUS) to suit
most applications. The lubricants have excellent
thermal and chemical stability, and are compatible with a
wide range of elastomers, polymeric materials and other
materials of construction.

Additionally, their higher viscosity index is an indication
that their effective viscosity will not change drastically
with the wide swings in temperature seen by most typical
refrigeration and air conditioning systems. They are the
preferred choice for servicing and retrofitting existing
equipment as well as for OEM charging.
