FILOIL 1500

Transformer oil treatment plant

FILOIL 1500 dries, degasses, and filters mineral transformer oil to the condition the asset needs — on energized or de-energized transformers, in the field or on the production line. The most compact unit in the line, it goes where larger plants cannot and runs continuously once it is there.

  • Vacuum dehydration and degassing in a single pass
  • Operates on energized or de-energized transformers
  • Engineered for mineral transformer oil
  • Stationary or mobile configuration

FILOIL 1500

Overview

What FILOIL 1500 does

FILOIL 1500 brings transformer oil back to specification. Moisture, dissolved gases, and particles accumulate over years of service and pull the oil's dielectric strength down; in a single pass, the unit dries the oil under vacuum, strips dissolved gases, and filters particles to 0,5 µm, and the oil goes back to work.

The unit runs on energized transformers, so the work happens without an outage. The same plant handles oil filling for new transformers, treatment of storage tanks, and oil transfer between vessels. Operation is fully automatic, with PLC control and SCADA integration for sites that monitor remotely, and a full set of safety interlocks for unattended running.

For the underlying chemistry of moisture, oxidation, and dielectric performance, see the Handbook of Transformer Oil Excellence.

Application

Best suited for

FILOIL 1500 is the unit for distribution transformers and smaller assets, for service work on sites where space and access are limited, and for oil filling and tank treatment at lower volumes. For higher throughput, FILOIL runs up to 24 000 l/h.

Engineered to a different standard

  • The stadium chamber

    A vacuum chamber no one else builds. The stadium shape enlarges the processing area, gives the oil a second degassing pass, and puts a flat wall where foam can be watched and controlled.

  • Foam under active control

    Side-mounted sensors read foam height in the chamber in real time. When it rises, the PLC eases the vacuum or the flow, your choice, with no air let into the process. The enlarged shape carries more foam before it matters.

  • Upgrade without welding

    Coalescers screw in and out. Add processing capacity later as a retrofit, with no welding and no cutting into the vessel.

  • Vacuum held to setpoint

    The regulation valve sits on the vacuum line, not the chamber, so no air enters the process. The PLC holds the vacuum to whatever level you set.

  • Runs itself. Watches itself.

    Fully automatic PLC, with a full SCADA and on-board edge analytics. Manual controls are PLC-guarded. The wrong move is blocked before it happens.

  • Connected as standard

    An integrated modem and on-board server push every reading to ekofluid.cloud. Your portal holds the full history and the documentation. Log in and run the unit from any browser.

  • Inline oil analysis

    Optional onboard sensors for moisture, dissolved gas, tan delta, and breakdown voltage. Readings flow straight into the SCADA.

  • Heaters built to your loading

    Modular heaters, specified to your own watt/cm². Welded only from outside the vessel, then insulated. Low surface load, no local overheating.

  • Filters changed in minutes

    Redesigned casings unscrew by hand. Inlet and outlet share one cartridge type, so you stock one spare. Your choice of beta ratio and micron rating.

  • Routed your way

    Bypass lines as standard, so oil can take several paths through the system. The vacuum alone can draw oil through if the inlet pump is down, and pull oil back out of the hoses before disconnection.

  • Mounted however the site needs

    Each frame sits on the ground, on forklift-friendly legs supplied as standard, or on an optional wheel base. All detachable.

  • Access designed in

    Two-way enclosures open top and side, past 90°. Every valve reachable, every gauge readable from the side. A dedicated review checks operator access on every build.

  • Built to outlast the asset

    Black steel, fully welded, dual-coated and baked. Secured stainless drain hoses on every vessel, and a catch tray that drains down at the end of the day.
