Application

Series ZYD Double-stage 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 safelyand normally. 

 

Features

1. Double-stage vacuum system, 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. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing 

components, can rapidly and effectively separate water, 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. 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 oil filling.

 

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.
