Automatic Vacuum Transformer Oil Oil Purifier is designed to process and maximize dielectric strength in electrical insulating liquids - including mineral oil, natural esters, synthetic esters, silicone oil used in transformers, tap changers, circuit breakers, and other oil-filled electrical devices.
HOPU Enclosed Oil Purifier Application
Weather-proof canopy enclosed type transformer Oil Purifier installed with weather-proof ,dust-proof canopy, it is can be working for outdoor area.
The steel enclosure canopy is suitable for weather-proof ,dust-proof site working
The aluminum enclosure canopy is IP55 protection.
It is is professional for treatment of transformer oil, suitable for outdoor oil filtration, vacuum oil injection and cyclic hot oil drying in the installation and maintenance of large capacity transformers.
Double-stage High Vacuum Transformer Oil Filtration Machine is a ultra high vacuum oil dehydration system for Dielectric Transformer Oil Purification and Oil Filtering. This transformer oil filtration equipment 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 equipment working safely and normally. It's particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work on-site. Meanwhile, it can be used as independent vacuum resource with functions of vacuum drying and vacuum oiling.

Weather-proof Canopy Transformer Oil Purifier for outdoor service Features
1. Weather and dust resistant, convenient for outdoor use.
2. And it has double-stage high pumping speed vacuum system, multistage stage vacuum analytical separation system, it can quickly separate out water, gases, impurities, polar substances and other deteriorated materials.
3. Adopting the three-dimensional flash evaporation dehydration and degassing technology, it high efficiently separates water, gases from the oil, making the breakdown voltage rapidly increase to above 75KV.
4. Adopting the complex high speed degassing spiral flow structure, oil gas separate dual channel technology, re dissolution technology in anti oil gas separation, it quickly removes various organic hydrocarbon gases, ensuring no acetylene and hydrogen in oil.
5. Adopting carbon fiber infrared heating, grouped ultra low surface load, PID constant temperature control and dual temperature flow protection technology. Inside the machine installed the the diameter increase oil flow direction turning overflow technology to prevent "dead oil area", over-temperature and drying.

6. Adopting multistage high β value compound filtration system, linear coupling filter seal, it can effectively filter even the tiny particles mechanical impurities.
7. Specially made precise oil pump with low noise meeting environmental protection requirement.
8. Online filtering oil; with nobody watching is okay, and it can also be used for vacuum oiling the transformers etc and drying its hot oil.
9. Equipped with advanced infrared liquid level auto control system, auto defoaming control system, pressure protection system and safety interlock control to ensure that the equipment work for long time, safely and reliably.
