Transformer Oil Purification Machine 6000LPH Highly Recommended
We are delighted to share real on-site photos of our ZYD-100 double stage transformer oil purification machine, which has been installed and commissioned for transformer oil purification at a power project in Algeria. This vacuum transformer oil purification machine is built for heavy-duty transformer oil dehydration, degassing and particle filtration, serving power substations, transformer maintenance contractors and power utility clients across North Africa.




The ZYD-100 double stage vacuum transformer oil purification machine features a rated processing flow of 6000LPH, designed to treat insulating oil for high voltage power transformers. The core advantage of this double stage transformer oil purification machine lies in its two-stage vacuum combination: Leybold SV-100B rotary vane vacuum pump paired with Huaxin Nanguang ZJP-150 Roots booster pump. The vacuum pumping capacity reaches 540 m³ per hour, which quickly removes dissolved water, free moisture, air and volatile gas inside transformer insulating oil. Compared with single stage vacuum oil purifier, double stage vacuum design achieves deeper vacuum and better dehydration effect, greatly improving the dielectric strength of transformer oil.
For oil conveying, this transformer oil purification machine adopts Italy SEMP YPXF series screw pump, matched with reliable ABB M2BAX series motor. Two SAKO variable frequency drives (VFD) are equipped on this ZYD-100 transformer oil purification machine, supporting stepless flow adjustment. Operators can adjust the oil flow rate flexibly according to different oil conditions and working requirements. Variable frequency control protects the pump system, reduces startup impact and extends the service life of the whole transformer oil purification machine.
Automatic control is realized by Siemens PLC controller, making the transformer oil purification machine easy for field operation. Online EE364 moisture sensor is installed at oil inlet and oil outlet of the vacuum oil purifier. The EE364 sensor continuously monitors the moisture content of transformer oil in real time during oil purification process. Field technicians can check oil moisture data without taking offline oil samples, improving working efficiency for transformer maintenance.

A three-stage graded filter system is integrated in this ZYD-100 transformer oil purification machine. The filters separate contaminants according to different impurity particle sizes layer by layer. This layered filtration technology improves the overall filtration precision of the vacuum transformer oil purifier. More large particles are trapped in the front filter stage, so fine particles go to later filter cartridges. This design effectively reduces filter clogging, extends filter element service life and lowers the operation cost of transformer oil filtration work.
Our ZYD series double stage transformer oil purifier covers multiple flow rates from small ZYD-30, ZYD-50 to large capacity ZYD-100, ZYD-150, even ZYD-300 vacuum oil purifiers. These oil purification machines are widely used for new transformer oil processing, on-site transformer maintenance, old insulating oil regeneration, transformer oil dehydration and degassing for power plants and substations.
For power engineering clients in Africa and worldwide, choosing a high-quality transformer oil purification machine is critical to protect power transformers. Water, gas and solid impurities in insulating oil will reduce BDV value and shorten transformer service life. The ZYD-100 double stage transformer oil purification machine can restore insulating oil performance efficiently on site.
