This oil filtration system is applied to treat various of unqualified insulation oils including aging transformer oil, mutual inductor oil, switch oil. Also it can inject the insulating oil into the transformers. The functions include: dewatering, degassing, removing the impurities, and recovering the oil's original function.

.

1. Duplex 3D stereo-evaporation technology, dewatering and degassing effectively.
2. Distinctive remove the impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power.
3. Infrared liquid level automatic controller system
4. A trio of inter locked preventive device. 
5. It can work independently, also it can work with the oil regeneration system
6. Vacuum oiling of power equipment and drying moisture of power equipment
7. Automatic testing the oil dielectric strength and printing out the result (Specially Series ZYA)
8. Can be operated both on-load and off-load.

Series ZYD-I is applied to purify and regenerate the used insulating oils includes transformer oil, switch oil, circuit breaker oil, capacitor oil, mutual inductor oil in power generation plants, transformer stations, electric transmission and supplying company, factories, mines, railway transportation, etc. It can be used as special equipment for electric power transformer maintenance. Not only can it remove water, gas, and other impurities from the oil, but also it can remove oxide materials and remove free carbon in the deteriorated oil to lower the PH value, improve its breakdown voltage and quality, recovery the oil color. After treating, the insualting oil can reach international standard and recover its original function.

  Waste oil recycling process 's Technical Data:

Structure Chart:

The oil technical data after treatment:

• Gas content less than 0.1%
• Impurity size less than 1μm without free carbon
• Oil dielectric strength (breakdown voltage) more than 75KV
• Acidity value less than 0.01 mgKOH/g
• Dielectric loss factors at 90°C less than 0.001

  Waste oil recycling process 's Advantage:

It's a new-type of high effective vacuum oil purifier with the duplex 3D stereo-evaporation technology and G technology. Also it adopts the technology, which remove the impurities  through double FH trapezoidal network and absorbing by high polymer without the mechanical power. So it's five or eight times as effective as the common vacuum oil purifiers, the consumption of energy is least and it's doesn't need other wearing materials.

Q: How can we achieve drying without elevated heating of the insulation material for transformers?
A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
