This equipment is a new multi-function vacuum oil purifier device, based on pure physical cryogenic distillation and microfiltration purification technology. The whole equipment is with no filter, high-speed rotary motor (non-centrifugal effect). It adopts unique patents technology -- decoloring process, and separation of the oxides in the waste oil, residual carbon, resin, and the chromosome, no acid-base process. This equipment not only processes the oil to transparent and translucent color, but also restores properties of oil, and oil physical and chemical indicators (according to the acceptance of national standards GB). With dual-match and dual-control technology, that is with dual pump, dual control, turbine circulation pump, which characterizes strong thermostability and wear resistance, no leakage, do not need replacement. Machine configuration is more reasonable, more secure, with more stable performance and more convenient operation.
