Compressor Oils Range

The range covers the needs of compressors, refrigeration system and vaccum oil pumps. Formulated with rust & oxidation inhibitors to prevent deposit formation in high temperature systems, anti-wear additives for long life under severe conditions. Other formulations with napthenic & ester synthetic base oils are tailored for refrigeration systems which required low pour point & high thermal stability. 

ADVANCED FULLY SYNTHETIC VESTA COMPRESSOR OIL Series

United Advanced Fully Synthetic Vesta Compressor Oil is a premium performance, synthetic compressor oil based on polyalphaolefin and ester technology. It contains a rust and oxidation inhibitor system plus anti-wear additives to provide outstanding oxidation resistance and corrosion protection. High viscosity index and low pour points of the polyalphaolefin base fluid permits application in a wider range of ambient operating temperatures than with conventional lubricants. It provides long oil life and effective lubrication in severe applications.

United Advanced Fully Synthetic Vesta Compressor Oil is recommended for lubrication of reciprocating, rotary screw slide vane air compressors where the air delivery temperatures are greater than 150°C. But not recommended for use in breathing air compressors.

VESTA SYN S REFRIGERATION OIL Series

United Vesta Syn S Refrigeration Oil is blended with the selection chemical additive, the high quality naphthenic base oil and the special function double ester synthetic base oil. It is good with the halocarbon refrigerant's solubility to helpful in avoids the oil separation which freezes the system usually to occur and congeals frozen in the valve and the heat transfer surface question.

It has low pour point that is helpful in prevents the harmful waxiness precipitation, especially designed for the freezer lubrication use. United Vesta Syn S Refrigeration Oil has chemical stability, no reaction with the refrigerant and high thermostability that is helpful in prevents the oil the decomposition.

It is suitable for all freezing compressor type: The reciprocating and rotary refrigeration compressors with the fluorine carbon refrigerant. But it cannot be used together with the sulphur dioxide or R134A refrigerant. According to the compressor manufacturer's recommendation, select the specific viscosity grade oil.

VESTA S REFRIGERATOR OIL Series

United Vesta S Refrigeration Oil is a naphthenic-based compressor oil with low carbon forming tendencies. It is specially formulated for reciprocating and rotary refrigeration compressors in air conditioning systems or refrigeration systems with chlorofluoro-carbons (CFCs) (eg. R12); ammonia (eg. R717); hydrochlorofluorocarbons (HCFCs) (eg. R22); carbon dioxide (CO2) (eg. R744); sulfur dioxide (SO2) or ethylene chloride (C2H4Cl2) as refrigerant. Nevertheless it was not suitable for systems containing HFC refrigerants (eg. HFC 134a).
