Transformer oil purifier

Key Attributes.

ZYD series double-stage transformer oil purifier is specially designed for improving oil's dielectric strength and making sure electric equipments working safely and normally. ZYD machine equipped with double-stage vacuum system, it can quickly and effectively remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from unqualified insulating oil. ZYD transformer oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. Main features: 1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value < 5Pa 2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and greatly improve dielectric strength. 3. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil. 4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies 5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable. 6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely. 7. The ZYD machine adopts advanced technology, the final treated oil can achieve: Water content less than 3ppm Particles size less than 1 micrometer It can be used for filtration of more than 110V substation live line work onsite. Also, ZYD transformer oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.
