High Vacuum Transformer Oil Purifier for 110kV–500kV Power Transformers

High Vacuum Transformer Oil Purifier for 110kV–500kV Power Transformers

NSH Insulation oil purifier is widely used in oil purification,vacuum drying and oil filling machine during installation and maintenance of various transformer. Compared with single-stage vacuum oil filtration machine, this machine adds Roots pump system, secondary high vacuum separation system and three-dimensional flash rapid evaporation system. With functions of dehydration, degassing, de-acetylene, de-acidification value, removing the free carbon, and improve the breakdown value(BDV) of transformer oil.

• VF series-- Single-Stage Vacuum Insulation Oil Filtration Machine. Cheap price for option.
• VFD series-- Double-Stage Vacuum Transformer Oil Filtration Machine. High Quality transformer oil output.
• VFD-R series-- Double-Stage Vacuum Insulation Oil Regeneration Filtration Machine. Remove the black carbon free.

The double stage transformer oil purifier with vacuum separation, precise filtration, molecular adsorption, vacuum drying, spiral spray atomization separation, molecular adsorption and vacuum drying principle to remove moisture, gas,impurities, free carbon, acid value, transformer oil acetylene(C2H2 gas), etc., oil treated can reach the requirement and reuse.

This is double stage transformer oil purifier, with higher vacuum than single stage, the higher vacuum separation system, three-dimensional separation column system, emergency rapid flash evaporation technology, it can dewater, degass and remove impurities faster, more thorough, improve the transformer oil breakdown voltage more. Also it is available as an independent vacuum drying unit and oil refilling machine for transformer.

• Normal appearance type,shelf-covering type and explosion-proof type. Protecting the machine for long time use.
• Fixing type,mobile type with four wheels and mobile type with trailer. You can use it in factory.
• Colors is customized as you like.

Transformer Insulation Oil Purifier Machine solves these problems by:

• Double-stage high vacuum system for rapid water and gas removal
• Multi-stage filtration for solid impurities and trace particles
• On-site hot oil circulation / transformer drying capability
• PLC-controlled automatic operation, reducing labor and human error
• Mobile and stationary options for flexible deployment

TF series: Turbine oil purifier system is particularly suitable for purifying turbine lubricating oil. It also applys to treat hydraulic, coolant oil and other lubrication in which contain large of water, vapor, impurities, sludge, dielectric and colloid. It can eliminate them effectively and efficiently.

LV series: Lubrication Oil Filter System are suitable especially for purifying and restoring hydraulic oil, machine oil, coolant oil and various other lubrication oil.

GER series: Ger Used oil regeneration system is suitable to regenerate used internal-combustion engine oil including diesel engine oil, gasoline engine oil, and used hydraulic oil, other used lubrication oil of machinery.

GED series: GED Series waste oil distillation machine is used to recycle all kinds of waste oil into base oil or diesel oil with high quality.
