Application(oil filtration, oil purification, oil recycling, oil treatment, oil regeneration, oil restoration, oil filtering, oil filter, oil purifier, waste oil disposal, oil reclaiming, waste oil management, energy saving, oil reconditioned, oil reconstituted, oil restituting, oil recovering, oil recuperation, oil filtrating, used oil, industrial oil, oil remediation, oil processing)
Vfd series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. From the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. Vfd series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.

I. Series zyd double-stage vacuum transformer oil purifier machine is mainly used for purifying the insulating oil, transformer oil, mutual oil, switch oil, dielectric oil and so on. Specially, it works with the regeneration system, can decolor for the badly waste transformer oil with a high efficiency.


V. It can vacuum filling oil to transformer, vacuum dry transformer and on-line operation transformer .

Vi. The standard zyd system is designed for processing oils in workshops, in storage tanks or directly in transformers (energized or de-energized transformers).

Vii. The oil technical data after series zyd oil purifier machine treatment:
1. Gas content less than 0.1%
2. Impurity size less than 1m without free carbon
3. Oil dielectric strength (breakdown voltage) more than 75kv
4. Acidity value less than 0.01 mgkoh/g
5. Dielectric loss factors at 90c less than 0.001

Used Engine Oil

Series ZYD Double-Stage Vacuum Transformer Oil Purification Systems is used for transformer oil dehydration and transformer oil degasification as well as other electrical insulating liquids such as silicone fluids. The ZYD Process is able to increase and maintain the oil's dielectric strength and includes the removal of free and soluble water, free and dissolved air and gases and other particulate matter. The standard ZYD system is designed for processing oils in workshops, in storage tanks or directly in transformers (energized or de-energized transformers). Series ZYD oil purifier can be used as an independent vacuum source with functions of vacuum drying and vacuum oiling.


Feature
1. ZYD can evacuate the vacuum for the electric equipments separately, such as the transformer. Also it can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum state.

2. This machine have two vacuum pumps (one is the vacuum pump, other one is the roots pump), which can improve the working value highly. Making sure the water-content of the treated oil is less than 3 ppm.

3. The machine adopts the double-infrared liquid automatic controller, pressure automatic-protector which can make sure the machine works online for 150 hours continuously without person. So it is a reliable and high automatically machine.

4. Besides the common vacuum oil purifiers function of dewatering, degassing, and removing the impurity, this machine can regenerate the seriously bad oil by separating the electric-polarity materials, such as deeply oxides and free carbon from the oil effectively. The treated oil can reach the specifications of the new oil, such as the oil dielectric strength, flash point, acid value and oxidation resisting etc.
5 Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies

6. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.

7. Adopt 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 live line work onsite, vacuum drying and vacuum oiling.


Advantages:
Comparing with single stage transformer oil purifier, Series ZYD oil purifier can increase the effectiveness more than three times, more quickly and completely dewater, degas, remove particles to get higher dielectric strength. This equipment can be used as independent vacuum source with the functions of vacuum drying and vacuum oiling for the electric plants.
