Through the use of highly stable PAO base oils, NEXT PAO will offer a lower oil carryover rates then mineral oil as well as formulations composed of PAO/AB blends. This formulation is ideal for systems operating at low temperature or in systems experiencing oil return issues. NEXT PAO has a robust anti-oxidant package that ensures excellent protection against thermal degradation and oxidation.
Applications
Reciprocating compressors
Rotary screw compressors
Gasses
Hydrocarbon gasses, for example: Propane (R-290), Butane (R-600), Isobutane (R-600a)
HFC gasses, for example: R-22
CO2 (R-744)
Note that for ammonia (R-717) systems NEXT PAO is not recommended, but SYN 717 is.
Benefits
Superior low temperature fluidity and oil return properties
Very low oil carryover rates
Excellent seal compatibility
Minimizes defrost cycles
Long fluid life
Excellent chemical stability
