I.Application
VFD-R series double-stage high efficiency vacuum insulation oil regeneration purifier is adapt to regenerates and activate the deteriorated transformer oil.
It is capable of removing the moisture gas and mechanical immpurities as well as eliminating organic acid,sludges,pitches and dissociated carbon in the diteriorated transformer oil which we are difficult to be removed by conventional oil purifier plants.After the treatment,not onlythe technical specification but the color of the insulation oil would be dramatically improved.The regenerated insulation oil can meet the required standard and life span of new insulation oil. 
II. Features
1.VFD-R regeneration units adopt both physical and chemical methods to purify and regenerate the transformer oil.They can not only regenerate the aging transformer oil,switch oil but remove the acid,suspending materials and contaminates.
2.VFD-R regeneration units adopt special absorbent.They can be normally run without switching off the power and changing transformer oil.
3.After the treatment,the transformer oil will maintain basic ingredients and anti-oxidation capacity to meet the standard of new transformer oil.Meanwhile,the VFD-R regeneration units can keep the power  equipments insulating and safe by consuming only 90% maintenance cost.
III.Technical Specification
After the treatment,performance of transformer oil can achieve the below specifications:
1.Breakdown voltage≥75KV
2.Flash point(close)≥140℃
3.Soluble acid PH value=5～7
4.Dielectric loss tangent tg(90℃)%≤0.002
5.Acid value≤0.01mgK0H/g
6.Power:380V/3P/50Hz(or as needed)
IV.Available Style
1.Fixing type,mobile type with four wheels and mobile type with trailer.
2.Avaliable in different color.
