Application: Vacuum transformer oil purifier machine is popular in electric power industries, this machine mainly purify and recover old insulating oil, like the transformer oil, mutual inductor oil, cable oil, and switch oils. For the insulating oil, the trace water and gas badly effect insulating oil dielectric strength, it is a good job to remove the trace water and gas completely and effectively. Vacuum distillation way is best way to remove trace water and gas, the treated oil moisture can reach to 3 ppm, gas content is 0.01%. ZY single stage vacuum transformer oil purifier. It is low price, and good working performance. It is very good for middle/low grade transformer oil purifying working. Also, this oil purifier can be used to power equipments to vacuum drying, and vacuum oiling.
