FILOIL 3000 est

Ester oil treatment plant

FILOIL 3000 est dries, degasses, and filters natural and synthetic ester transformer fluid to the condition the asset needs — on energized or de-energized transformers, in the field or on the production line. The compact ester unit, tuned to ester properties and built to run continuously.

  • Vacuum dehydration and degassing in a single pass
  • Treats natural and synthetic esters
  • Operates on energized or de-energized transformers
  • Stationary or mobile configuration

Overview

What FILOIL 3000 est does

FILOIL 3000 est brings ester transformer fluid back to specification. Esters hold more water than mineral oil by nature, and moisture, dissolved gases, and particles still pull dielectric strength down over time; in a single pass, the unit dries the fluid under vacuum, strips dissolved gases, and filters particles to 0,5 µm, tuned to ester properties throughout.

The unit runs on energized transformers, so the work happens without an outage. The same plant fills new ester transformers on the production line, conditions fluid in the field, and handles transfer between vessels. Operation is fully automatic, with PLC control and SCADA integration for remote monitoring, and a full set of safety interlocks for unattended running.

For the chemistry of ester fluids, moisture behaviour, and dielectric performance, see the Handbook of Transformer Oil Excellence.

Application

Best suited for

FILOIL 3000 est is the unit for distribution and medium ester-filled transformers, for service work on renewable and ester installations, and for ester filling at moderate volumes. For larger transformers and higher throughput, FILOIL est runs up to 9 000 l/h.

Engineered to a different standard

  • The stadium chamber

    A vacuum chamber no one else builds, and an engineering challenge to get right. The stadium shape enlarges the chamber and the processing area, makes room for more coalescing stages, and gives the fluid a second degassing pass on the way through.

  • 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.

  • Tuned for ester chemistry

    The whole process is set up for natural and synthetic esters, not mineral oil. Esters hold more water by nature, so drying, heating, and filtration are tuned to ester properties to bring the fluid back to specification.

  • Heating built for esters

    Esters are more viscous than mineral oil and need more thermal input, so est. units carry higher heating capacity. Modular heaters specified to your own watt/cm², welded only from outside the vessel. Low surface load, no local fluid degradation.

  • Capacity that grows

    Coalescers mount on a threaded fitting, so processing stages are added later as a retrofit, with no cutting and no welding into the vessel.

  • Vacuum held to setpoint

    The regulation valve sits on the vacuum line, ahead of the pump, not on 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.

  • Interlocked for every scenario

    Alarms, sensors, and interlocks across every condition the unit can meet. Designed to run safely, attended or unattended.

  • 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 fluid analysis

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

  • Built for the production line

    The same plant that conditions ester in the field equips an ester production line in the factory, drying, degassing, and filling new transformers to specification before they ship.

  • 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.

  • Mounted however the site needs

    Each frame sits on the ground, on forklift-friendly legs supplied as standard, or on an optional wheel base. Stationary on the line or mobile to the wind park, all detachable.

  • 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.
