Industrial air compressor fluids with excellent oxidative stability and strong resistance to sludge and varnish formation
COMPRO Synthetic
Group V (PAG)Designed for rotary screw air compressors in severe applications including high/low temperature extremes. Outperforms PAO synthetic fluids at high discharge temperatures with up to 1 year continuous service or 8,000 hours. Compatible with standard seal and hose materials.
Suitable gases: Air, nitrogen, argon, hydrogen, neon, helium, CO₂, CO, blast furnace gas
COMPRO XL-S
Group III+Extends fluid life in rotary screw compressors with 8,000+ hour service intervals
COMPRO
Group IIResists oxidative breakdown better than leading mineral oil based fluids
COMPRO E
Group V (Ester)Ester-based fluids compatible with PAG fluids and mineral oils. Recommended for single/multistage air compressors: rotary vane, rotary screw, reciprocating, and centrifugal. Can be used as short-term flushing fluid for oil-flooded screw and reciprocating gas compressors.
Compressor types: Rotary vane, rotary screw, reciprocating, centrifugal
Recommended: Teflon, Viton, High Nitrile Rubber-Buna N (>36% nitrile)
Fair compatibility: Nitrile Rubber-Buna N (30-36% nitrile), Silicone Rubber, Ethylene-Propylene Terpolymer, Polyacrylate Rubber, Epichlorohydrin
Not recommended: Natural Rubber, Neoprene, Nitrile Rubber, Butyl Rubber, Polystyrene
Note: Not all viscosity grades are suitable for all compressor types. Follow OEM recommendations and operation manual for specific brand/model.
REFLO
Industrial Ammonia Refrigeration
Refrigeration compressor fluids for large industrial ammonia (R-717) plants such as cold storage, food processing and blast freezing, built for long oil life and low carryover
Running HFC/HFO refrigerants, AC, heat pumps or a commercial OEM compressor? Use SUNISO instead.
Compare SUNISO and REFLOREFLO A meets requirements of major compressor OEMs:
Bitzer • Frigoscandia • GEA VXHP • Grasso • Howden • Huppman • Sullair • Vilter • Mayekawa/Mycom (Screw Compressors)
REFLO A
Group IIAn ammonia refrigeration compressor fluid with low ammonia solubility, so less oil carries over into the system. NSF H2 registered.
REFLO XL
Group III/IV BlendA synthetic blend with seal conditioners and anti-wear protection, ideal for reciprocating ammonia compressors. Outperforms straight Group II paraffinic and naphthenic oils. NSF H2 registered.
REFLO Synthetic
Group IV (PAO/AB)A polyalphaolefin/alkylbenzene ammonia refrigeration fluid for blast freezers and evaporators down to -51°C (-60°F)
REFLO CFC
Group I (Naphthenic)A naphthenic fluid for legacy CFC systems, and for ammonia systems already running a naphthenic oil where seals can't be changed out
Important:
REFLO products are not recommended for top-up on pre-existing refrigeration compressor fluids with different chemistries. REFLO A, XL (paraffinic) and Synthetic (PAO) should not be mixed with naphthenic or aromatic type fluids. REFLO CFC is a naphthenic fluid and should not be mixed with paraffinic fluids. Mixing incompatible chemistries increases risk of system issues.
