Sun brand frozen oil Features 1. Chemical stability: does not exist with the refrigerant in the system, or other material to chemically react. 2. Thermal stability: not accumulate excessive carbon deposits in the hot parts such as discharge valve. 3. Low wax content: to prevent the oil / refrigerant mixture at low temperatures to form part of the system waxy flocculent precipitate. 4. Low pour point: to prevent the precipitation of the oil solidifies in the pipeline. 5. High dielectric strength: to ensure good insulation properties. In the sealed unit, the oil / refrigerant mixture is applied between the motor and compressor insulator. 6. Moderate viscosity: Although it is diluted refrigerant, still at a very high temperature operating conditions with a high film strength. Meanwhile, at a very low temperature conditions, can still maintain a good flowability. 7. Pollution: to prevent abrasions bearing surface, blocking pipes and premature aging.
