ZJA Two-Stage High Efficiency Vacuum Oil Purifier Series for
ZJA is widely used in electric power, transforming electricity
industry, metallurgy, chemical engineering, traffic, railway and
others. It is designed for the vacuum filter of expensive oil such
as fresh oil, imported oil, instrument transformer oil, extra-high
tension transformer oil (cover110v, major transformer), and for
vacuum oiling, and drying of transformers. This filter can live
line work on the spot.
Advanced dehydrating and degassing system that uses large area
three-dimensional flash distillation technique to remove harmful
composition in the oil such as water, air and gas.
It can be widely used for filling oil into transformers and circuit
breakers under vacuum condition.
Precise filtration system, high-quality filter element, multi-stage
filtration with gradual precision can help to remove mechanical
impurities from the oil.
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, Function of
automatically detecting the pollution degree of filter element.
Online work, allowing separated operation of manual operators from
machine with lamps indicating the condition for operation.
It is humanization design with low noise, deep purification and
long time free maintenance to save cost from the running process.
Purifiers are equipped with a chain safety protective system, an
interlocking of oil drainage system, vacuum system and heating
system, which avoids any possible negative impacts caused by
