PureTech Transformer Oil Purification machine (Model DVOP) is designed for removal of particulate matters,as well as thermal vacuum oil drying and oil degassing of insulation oil and lubricant with viscosity of no more than 70 cSt at 50C.
The oil filtration unit can be used for heating of oil filled electric equipment with hot transformer oil, thermal vacuum drying of transformers and evacuation or transformers. The unit is designed for installation, repair and operation services which process transformer oil.
• Removal of Water from 50 ppm down to 3 ppm after 3 passes.
• Reduction of Gas Content from fully saturated with air (10 to 12% by volume) to less than 0.1 %.
• Removal of Particulate Matter to 1 micron.
• Improval of Breakdown Voltage (Dielectric Strength) up to 75KV.
• Especially designed "T" type vacuum chamber enlarges the oil evaporation area, achieve better effect of oil degassing than traditional vertical chamber type. (Note: double horizontal chambers are avaliable.)
• Three stages particulate filtration capacity ensure the promising cleanliness level.
• Sufficient vacuum with most efficient oil processing and oil dehydration capability.
• Automated operation on online and offline transformers.
• With design of Vacuum Trap, which can prevent transformer oil from entering vacuum pump system.
• One machine, multi functions.
• Long service life and less maintenance cost.
• Supplied with in-line moisture meter (OPTIONAL) and in-line oil flow counter (OPTIONAL) for your own oil degassing project or service companies.
