China Portable High Vacuum Insulating Oil Purifier Dielectric Oil Filtration Equipment Zy

Product Description

Product Description

 ZY series single-stage vacuum transformer oil purifier is mainly used in electric power project, petroleum, chemical, mining, metallurgy, manufacturing and other industries to purify various types of unqualified insulating oil, such as No. 10, No. 25 No. 45 transformer oil, mutual inductor oil, cable oil, switch oil, etc. 

ZY series Transformer Oil Purifier adopts Duplex-Stereo film evaporation technology, which can quickly and effectively remove water, gas and impurities from oil under vacuum negative pressure, restore and improve the dielectric performance of the insulating oil, and effectively guarantee Power equipment operates safely.

This machine can also be used for different purposes such as vacuum drying, vacuum oiling, and hot oil circulation.

 Oil Result after Filtration                                              

Moisture (Water Content) ≤ 5 PPM
Gas Content ≤0.1% (Vol)
Impurities Degree (Filtration precision) ≤ 5 micron (no free carbon)
Breakdown Voltage (Dielectric) ≥65 ~ 70 KV
Flash Point ≥130ºC
Cleanliness ≤NAS 1638 Grade 6

 1. Fully automatic operation controlled by PLC system, more easily and conveniently.
 2. Duplex-Stereo 3D film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
 3. Multi-stage precision filtration system, stainless steel filters’ filtration combined with molecular adsorption technologies, remove different sizes of impurities and particles thoroughly.
 4. Efficient carbon infrared electric heating system, heating uniformity, less power consumption, safe, and reliable.

 5. Double-infrared liquid level controlling system and pressure protective system ensure the machine operation easy and safely.
 6. 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.
 7. Fully automatic temperature controlling system, digital type temperature gauge and temperature sensor, monitoring and controlling oil’s actual heating condition and temperature.
 8. can works as vacuum oil filling machine, vacuum drying system and vacuum pumping system.
 9. Small volume, light weight, easily movable, low maintenance cost and time.
