White oil is also known as liquid paraffin wax, which is a highly refined mineral oils with characteristics of extremely pure, stable, colorless, odorless, non-toxic and chemically inert. These attributes make them perfect for any application that values these properties, such as pharmaceuticals, cosmetics and chemical processing. The term "white oil" is a misnomer, in that they are not white at all, but crystal clear. White oils can be produced from a variety of feedstocks, depending on the process used. These starting materials include conventional base stocks for the older acid treatment process to Vacuum Gas Oils (VGO) for the more currently widely used two stage hydrotreating method. Both processes produce colorless, odorless, tasteless oils where all components that might have any detrimental effects on their end usage, such as aromatics, sulphur or other impurities, have essentially been removed, resulting in a pure and thermally stable product Liquid paraffin has different flash points: 100, 120, 140 and 180, liquid paraffin (White oil) is produced for use in textile, spinning, industrial lubrication equipment, health products, produce clouds (polystyrene) according to its grades.

Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters. High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely. Utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly. Structure Dehydration (Degas) System 1, The vacuum chamber has flash tower, which can evaporate the water efficiently. Also it has the spraying nozzle with degassing elements design. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the flash tower of vacuum vessel is three times more than that of the general vacuum vessel. This innovation can dehydrate and degas effectively and efficiently. 2, The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization. ¡ô Filtering System (particulate matter removal) 1, The filtering materials with variable apertures are made of specialized glass fiber or stainless steel optionally. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method. 2, The filtering system has stable and prefect filtering fineness. The filtering fineness has several grades, including 0.5, 1, 2, 3, 5, 6, 10 Micron etc. Oil ¦Â>=1000 after filter. 3, The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully. Oil heating System 1, The unique heater structure heats the oil uniformly. 2, Oil Heater System assures less then 1.0 w/cm2. During the heating process, the deterioration of the oil caused by overheating is avoided. 3, The oil temperature can be adjusted between 20C to 80C. The heater is controlled manually or automatically. The heater will stop automatically when the oil temperature reaches a certain degree. 4, Being installed with safety protection devices, the heating system is secure and reliable. The heater will stop operation automatically when the oil volume of inlet is too low to avoid the damages of the heater. Electrical Apparatus Controlling System 1, The main components of the electrical apparatus made by Schneider, Siemens and so on ensure the safety of the controlling system. 2, Having several protection systems which will avoid oil ejection, overload and over voltage etc. Oil-level Controlling System 1, The oil-level floating ball or infrared liquid level automatic controller system are installed in the vacuum vessel to control the oil level so as to avoid the oil being suctioned into vacuum pump in the operation. 2, The new innovation of eliminating froth can avoid the oil being suctioned into vacuum pump. High quality components The main components parts of Tongrui products such as vacuum pump, Roots pump, oil pump and electric apparatus are from SIEMENS, LEYBOLD, OMRON, SCHNEIDER, HYDAC, TOP, AMICO etc. It ensures oil filtration systems products high quality and reliability.
