Application: 
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 purifier’s 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.
