Application:
ZYD Stainless steel transformer oil purifier is special for filtering the used and old transformer oil, mutual oil, switch oil. Comparing with the single-stage type, this machine adopts the double stages vacuum system, which can improve the machine's working vacuum value highly, so it can dewater, degas and remove the impurity more deeply and effectively. the dielectric value of treated oil is higher than 75KV. It is very suitable for the large electric & insulation equipments. 
Feature:
1. High vacuum: High point-Vacuum≤5pa Working-vacuum≤35pa 
2. High absorption speed: Absorption speed power≥333L/Sr.
3. Duplex 3D stereo-evaporation, eliminating the liquid wat er quickly 
4. Distinctive removing impurity system which filters the impurity through double FH trapezoidal network and absorbs the impurity by high polymer without the mechanical power. 
5. Carbon fiber infrared heating system that can have the oil contain zero sum of ethyne after the treatment. 
6. Especially applied to vacuum filling oil and drying for power transmission equipments which power are over 110KV.
7. Any insulating oil can be treated on-line at the working site.

Advantage:
Comparing with the single-stage vacuum oil purifier, this machine dewater, degas and removes the impurities more quickly, more completely, and makes the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system that can purify and also can be an independent vacuum power supply, this machine can treat the electric insulation devices.
