High Quality Two Vacuum Chambers Transformer Oil Recovery Device

-- ZYD transformer oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil.
-- ZYD 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.
-- ZYD transformer oil purifier can be used for filtration of more than (110KV) substation live line work onsite. Meanwhile, ZYD transformer oil purifier also can deal with switch oil, mutual inductor oil, cable oil, circuit breaker oil, capacitor oil and other insulation oil.
-- ZYD transformer oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum filling for transformers and electric equipments.

1.Double-stage vacuum system, vacuum pump and roots pump, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
2.Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3.Double-horizontal film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, dissolved moisture gas from oil.
4.Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
5.Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6.Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7.ZYD transformer oil purifier Adopts interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.
8.Functions of online work onsite, vacuum drying, vacuum oiling and vacuum filling of transformers and electrical equipment

Why do we choose oil purifier machine?

After a period of operation, owing to its expose to oxygen and mixed with water, copper and iron and other

foreign materials and high working temperature acceleration , transformer oil will oxidize and lose its

original property and cannot be used effectively again. So oil purifier machines can efficiently remove water,

dirt, gases and other foreign impurities from oil, such as turbine oil, lubricating oil, engine oil, hydraulic oil,

compression oil, mechanical oil, quenching oil, heat conducting oil, gear oil etc; so as to maintain its

lubricating and insulating property, then to reduce components wear, and cut down oil expenses.
