Introduction

ZYD-I provides purification such as degassing, drying and particulate removal,but also can remove acidity,sludge,other soluble oil decay products and discoloration. This is accomplished by the use of high vacuum degasification technology and particulate filters combined with our special brand of earth. ZYD-I series transformer oil purifier was specially designed to completely regenerate insulating oils in energized or de-energized transformers.
Comparing with the single-stage vacuum oil purifier, this machine dewater, degas and removes the impurities more quickly, more completely, and makes the oil BDV (Breakdown Voltage) of 75 kV or higher. The bridge-type vacuum linking system make it also can be an independent vacuum supply.
After treatment, the oil can be reused as new. For special application, the system also can be mounted on a leak proof base or be installed and operated on a trailer.

Features

1. Besides the common vacuum oil purifier's function of dewatering, degassing and eliminating particles, this machine can regenerate the seriously deteriorated oil by removing the polarity materials, such as the deep oxides, free carbon in the oil effectively. It can make the seriously deteriorated oil reach to the normal index.
2. For special application, the operation can be fully automatically controlled by P.L.C (Programmable Logic Controller).
3. Unique vacuum dehydration, degassifier, regeneration system to adopt stereo-evaporation technology for high-efficiently removing water, gas and particles, and improving oil quality and dielectric strength.
4. Duplex 3D stereo-evaporation, eliminating water quickly
5. UK g technology by which the trace water that is show chain, such as dissolved water, can be removed effectively.
6. Instinctive removing impurities system filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power
7. Advanced infrared liquid-level automatic control system to accomplish fully automatic control.
8. Specially applied to vacuum oiling and drying for power transmission equipments.
9. The oil of any grades can be treated either on- or off-load.
10. Special oil pump design with lower noise.
11. Special additives for depolarization, can recover oil color of aged transformer oil to new, equipped with flexible unloading device of short time, good efficiency small quality. Discolor under vacuum can save cost of treatment, the waste impurities doesn't pollute environment (it can be used for architecture and road paving).
