Rexon ZYD Technical Introduction:
The function of our series ZYD Transformer Oil Purification Machine is specially used to efficiently and quickly filter and purify the new or old transformer oil by removing all kinds of pollutants like water, dissolved moisture, air, gases, particles, and etc. from the transformer oil, so to guarantee the transformer oil's cleanliness degree, and make sure the oil can meet the standards for transformers use, and to guarantee the transformer's running safety and efficiency.
This ZYD oil purifier machine can completely remove all kinds of impurities, iron filings, dust, fine particles, visible water and trace water, and harmful gases for the used transformer oils and new transformer oils.
*Its working principle is to vacuum dehydrate and degas the transformer oil while heating the oil to be about 55~65ºC, which is allowed and has no harmful effect on oil. It simulates the environment of boiling water on a high-altitude mountaintop.
In an atmospheric pressure environment, we need to heat the water to 100ºC to boil water, while at high altitudes, we only need to heat the water to about 70~80 degrees. Therefore, The ZYD oil purification system will provide a super high vacuum environment (high negative pressure) for the transformer oil, and then heat the oil only to 55~60ºC, the visible water, trace water, and gases in the transformer oil will be totally evaporated. After the treatment, the moisture content in the oil can reach less than 3~5PPM (3~5 parts per million).
*At the same time, the machine adopts a three-stage impurity filtration system to remove large, medium, and small particle impurities in the oil. After filtering through the three-stage filter elements, the particle contaminants in the oil can reach an accuracy of 1 microns.
*In addition, the machine is equipped with advanced PLC automatic control technology and various monitoring devices, constant temperature heating control system, and doub le stages high-capacity vacuum pumps, which can greatly improve the working efficiency of the equipment and fully guarantee the safety of users using the machine.
Regularly filter and purify the transformer oil and insulating oil, the life of the oil will be greatly extended, their life will be greatly extended, and no replacement will be required for many years. At the same time, it ensures the safe use of transformers and insulating equipments and greatly extends their service life.

Why Need Rexon Oil Purifier?
Present and future transformer ratings require high quality and high purity insulating oils at the point of use. The increasing voltage and rating of the modern transformer and electrical apparatus results in greater electrical stress in insulating material and fluids. To handle these greater stresses, oils with better dielectric qualities are required. Also lower residual water content in insulating fluids and material must be maintained. The proper treatment and upgrading of the insulating fluid will result in the improvement of the properties of the entire insulating media of power transformers. The principal functions of the insulating fluid are to serve as a dielectric material and as an effective coolant. To perform these functions, the insulating fluid must have the necessary qualities at the time of initial impregnation and filling at the factory and later maintain the same quality in the field operation.
Rexon's High Vacuum Oil Purifier upgrades the new or used electrical insulating fluids including transformer oils, polybutenes. These systems and equipment were developed as a result of 50 years of experience in vacuum treatment of electric insulating fluids.
We are the leading manufacture near 20 years experience and supply best quality and highest cost performance oil purification machines.
