Series ZYD Double-stage transformer oil purifier can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's dielectric strength, effectively making sure electric equipments working safely and normally. Series ZYD oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.

Advantages:
According to the transformer oil change it is very economic
Used transformer oil can be brought up to the equivalent point of new oil
Transformer within the moisture, sludge, acids and harmful gases to destroy and the insulation values will be higher than old.
Transformer oil life is extended.
As a result of the occurrence waste oil and disposal costs would have been zero.
Waste oil has been blocked and prevented its negative given for the enviroment.
