Using the principle of vacuum evaporation, the saturation temperature is reduced under vacuum (for example, the boiling point of water at standard atmospheric pressure is 100°C, and when the residual pressure is 666.7Pa, its boiling point drops to 0°C), the oil which has a higher saturation temperature is sprayed and broken under vacuum, so that the water is fully evaporated and separated. Meanwhile, the temperature is not higher than the saturation temperature of the insulating oil, so the oil will not evaporate and will still flow to the lower part and be recovered in a liquid state.
The higher the vacuum degree, the lower the saturation temperature. (PureTech offers Single stage vacuum oil treatment machine, Double stages high vacuum oil treatment machine, Double chambers high efficiency vacuum oil treatment machine, etc. Please contact us for recommendations.)
Using a vacuum oil purifier, its oil dehydration and degassing capacity is dozens of times larger than that of a filter press and a centrifuge separator, and it can also remove the gas dissolved in the oil, with high efficiency, no oil and paper consumption.
