The proper purification process of dielectric insulating oils by DVTP70 (4200 liters per hour) Transformer Oil Filtration Machine will result in the improvement of the properties of the insulation system of power transformers. The 4000LPH Vacuum Transformer Oil Filter Machine can be mounted on skids or trailer to move easily from site to site.
DVTP70 (4200 LPH) Double Stages High Vacuum Transformer Oil Filtration Machine allows the purification processing in workshop, in storage tanks, drums or directly online purification of transformer oil in the field. Purification of oil in transformers can be carried out off-load or on-load depending upon customers' preference. The Transformer Oil Filter Machine also allows efficient drying of the insulating coil and vacuum evacuation of transformers while maintaining the transformer and also can be for transformers oil-filling.
4. Reduce particle counts to meet ISO 14/12/10 levels with 1 micron absolute
5. Reduce overall water content to 3 ppm after purification by transformer oil filtration machine.
Optional: Online moisture monitor, flow meter, oil regeneration system, weather proof canopy, double axles or single axle trailer, dielectric strength tester, etc.
