Refrigeration compressor oil is prepared by adding moderately refined low pour point naphthenic base oil with high-quality antioxidant compound additives. It has good lubricity, low temperature fluidity and excellent oxidation stability. DRA series refrigeration oil resources are stable, produced under strict quality control procedures, and the product performance is stable and reliable. DRA series refrigerating machine oil is divided into two categories: DRA/A and DRA/B according to the refrigerant and compressor type. The quality and performance meet the requirements of GB/T16630-1996 standard.
Application range
DRA/A series refrigerating machine oil is suitable for open-type ordinary refrigerating machines with ammoni-a (R717) as refrigerant. DRA/B series refrigerating machine oil is suitable for ammoni-a (R717). A semi-hermetic general refrigeration compressor or refrigeration unit with hydrochlorofluorocarbons (such as R12) as the refrigerant.
Features
Excellent low-temperature performance: Strict pour point and U-tube fluidity indicators can ensure that the oil will not condense in the low-temperature parts of the refrigerator, such as the evaporator, to meet the free switching requirements of the refrigerator from the high-temperature working area to the low-temperature working area ; Excellent oxidation stability: DRA series refrigerating machine oil is matched with an appropriate amount of antioxidant additives, which has better oxidation resistance, thereby effectively prolonging the oil change period of the refrigerating machine; suitable refining depth: to ensure that the oil will not be in the valve Carbon deposition occurs in high temperature parts, resulting in pipeline blockage; good cleanliness: the oil is transparent and pure, and has a cleaning effect on the working parts, which can effectively prevent the occurrence of foreign particles rubbing the surface of the bearing. DRA/B series refrigerating machine oil also has good chemical stability; it ensures the stability of the oil when it coexists with fr-eon refrigerants, and greatly reduces the occurrence of refrigerant decomposition and compression parts corrosion.
Product variety
Various grades such as DRA/A46, DRA/A68, DRA/B46, DRA/B68, DRA/B100 can be provided respectively. Other viscosity grades are also available upon request.
Precautions
During the transfer process of DRA series Lengdong engine oil, the used containers, oil tanks, pipelines, valves, etc. should be carefully cleaned and inspected before being put into use. Containers must be kept clean, protected from light, and stored indoors or in a controlled climate if possible. Storage containers must be waterproof, moisture-proof, and mechanically impurity-proof. There must be obvious marks during transportation to avoid confusion with other petroleum products. Do not contact the skin directly during use. If it is accidentally contaminated, remove it with soap and water in time, and dry it with a paper towel. Due to the different properties of the base oil, this series of products cannot be mixed with other refrigeration oil products.
