    China Factory Lyc-150b High Precision Offline Filtration ...
    Offline transformer oil filtration is a, highly effective maintenance process where oil is circulated through a mobile, external vacuum unit while the transformer is de-energized and disconnected. It removes water, dissolved gases, and sludge, restoring dielectric strength and extending insulation life without requiring oil removal.

    Key Aspects of Offline Oil Filtration 
    • Process: The mobile unit, such as an Acore VTP-D, extracts oil, heats it, and passes it through vacuum dehydration and degassing chambers before filtering particulate matter and returning it to the transformer.
    • Effectiveness: It is highly efficient for removing moisture (down to <10 ppm), dissolved gases, and particulates (
      <0.5is less than 0.5
      <0.5
       micron) to improve insulation efficiency and prevent failure.
    • Versatility: Suitable for on-site maintenance of power transformers, circuit breakers, and oil-filled equipment.
    • Equipment: Specialized equipment includes single or double-stage vacuum purifiers with heaters, particulate filters, and vacuum pumps, such as Ekofluid ECOIL machines, which offer filtration capabilities ranging from 200 to 8000 L/h.
    • Benefits: This procedure ensures high reliability of power systems and can include Acore portable filter carts for smaller, cost-effective maintenance tasks.
