Application:
Oils inside transformers are mainly for insulating purpose- apart from which they also suppress corona and arcing, and also act as coolants inside the machines. These oils must be maintained absolutely clean and dry in order to achieve and sustain the optimal insulating performance and dielectric strength. Here rises the need for transformer oil purification process. ASSEN ZYD Transformer Oil Dehydration Machine is the key to transformer reliability, performance and longevity. Your transformer's insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels.
Features:
1.A capability of reducing moisture content from 50ppm to 3ppm moisture and 12% gas content to less than 0.1% by volume. 98% of particulate matter will also be removed.
2. Double-Stage vacuum system,strong power of vacuum evacuating,ultimate vacuum value no more than 5Pa
3. Duplex-Stereo film evaporation technology,combined with unique and advanced dewatering,degassing components,can rapidly and effectively separate water, gas,from oil.
4. An advanced fully automatic temperature controlling system,liquid-level controlling system,defoaming controlling system,pressure protecting system and excellent configuration can ensure operation of the equipment with high performance
5. Online work,allowing separated operation of manual operators from machine with lamps indicating the condition for operation.
6 It is humanization design with low noise,deep purification and long time free maintenance to save cost from the running process.
After treatment,oil quality guarantees to the following specifications.
