China Double Vacuum Used Dielectric Oil Transformer Oil Filter Machine

1. Insulation Oil Purifier Machine
2. Improve breakdown voltage up to 75KV
3. High dehydration and degassing



In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, dielectric oils must be kept absolutely clean and dry. Substation Maintenance Contractors and Utilities need an oil filtration machine that can quickly and reliably process transformer oil to meet or exceed very stringent specifications, so TOP designs and manufacture the most effective, durable, and user-friendly machine running in almost each city of China and serving customers in 40 more countries with good reputation.

Re-refining to remove acids and particulate material
Dehydrating to remove free and dissolved water, including insulation dry-out of the windings.
Degassing to remove other dissolved combustible gases such as Acetylene, Ethylene, Ethane, Methane, Hydrogen and Carbon Monoxide, and Carbon Dioxide.
Index before purification(from customer for your reference):
water content ≤50ppm
gas content ≤10 %(by volume)
breakdown voltage ≥30KV/2.5mm
particle qty≤70000 (5-50micron)

Index after purification (test at oil-outlet of the machine):
water content≤ 5ppm
gas content≤0.1%( by volume)
acetylene content: 0
breakdown voltage≥75KV (Spherical polar)
particle qty in 100ml oil≤500 (5-50 micron), (0 for ≥100 micron particle).
dielectric loss tgδ≤0.3% (90°C)
acid value ≤0.1mgKOH/g
The oil technical data after treatment:
1. Gas content is less than 0.1%
2. Impurity size is less than 1μm without free carbon
3. Water content is less than 3 part per million
3. Oil dielectric strength (breakdown voltage) is more than 75KV
4. Acidity value is less than 0.01 mg KOH/g
5. Dielectric loss factors at 90°C is less than 0.001

High vacuum pressure and high flow rate. This product makes bridge with the electric equipments. Vacuum, filtration and oil injection can work independently and also they can work together. As the oil purifying nanotechnology, this machine can treat oil more quickly and more completely, and makes the oil limiting voltage-withstand value much higher than the ordinary vacuum oil purifier.

1. Transformer Oil Purifier:
This kind of machine is used to purify used transformer oils by vacuum separation technology to remove water, gas, particles.
2. Lube Oil Purifier:
This machine is to filter used lube oils, such as hydraulic oil, gear oil and other lubricants.
It can effectively break emulsification and completely remove water, gas, particles.
3. Cooking oil recycling machine:
This machine is used to recycle waste cooking oil, dirty vegetable oil, drainage oil, swill oil and animal oil etc., it effectively and completely removes particles, odor, water, gas, etc. from waste oil. The treated oil is clean and good smell.
4. Transformer Oil BDV Tester:
This tester with automatic operation system is ued to online monitor transformer oil's dielectric strength.
5. Oil Water Content Testing Machine:
This device is designed to test water content in oil to make sure the oil is suitable for further use.
