Our commitment: to provide genuine quality nourishment for refrigeration HVAC system! Beijing Jing Wei Sheng Technology Co., Ltd. Product parameters DRA Series frozen oil: [Performance] excellent low temperature performance: Strict pour point and U-tube liquidity indicators to ensure that the oil does not freeze in the cold machine components such as evaporators condensation, etc., to meet the needs of the freezer freely switch from high to low temperature workspace workspace; excellent oxidation stability: DRA Series frozen oil matching the right amount of antioxidant additives, with better oxidation resistance, thereby effectively extend drain intervals freezer; suitable refined depth: Make sure the oil does not produce carbon at high temperature valves and other parts, the occurrence of clogging the pipeline; clean good: pure transparent oil on the working parts have a cleansing effect, can effectively prevent impurity particles friction bearing surface phenomenon. ] DRA / B Series frozen oil also has good chemical stability: to ensure the stability of the oil and Freon refrigerants coexistence greatly minimizes refrigerant decomposition, compression parts are corrosion phenomenon; [Application Range] DRA / A Series frozen oil for ammonia (R717) as the refrigerant open type ordinary freezer. DRA / B Series frozen oil for ammonia (R717), HCFCs (eg R12 refrigerant for semi-hermetic refrigeration compressors or chillers common. [Model] available separately DRA / A46, DRA / A68 ., DRA / B46, DRA / B68, DRA / B100 five varieties may also provide other viscosity grades required Tel:. 010-57286377 13391817494 (08: 00-22: 00 7 × 14 hours) Jiang thick right
