The AE865C filters, dehydrates and degasifies insulating oil by high vacuum on a light cart, leaving less than 10 ppm of water and less than 0.25 % of gas at 230 litres per hour.
Advantages
High vacuum that goes low
The vacuum system reaches a blank-off rating below 0.025 mbar (20 µm Hg), the level needed to strip water and dissolved gases from the oil in one continuous process.
Results verified by ASTM methods
Output oil carries less than 10 ppm of water (ASTM D-1533 / D-1744, Karl Fischer) and less than 0.25 % of total gas (ASTM D-831 / D-2945); new oil reaches at least 40 kV of dielectric strength by ASTM D-877.
Sized for small oil volumes
With 230 l/h of throughput at 60 Hz, the cart matches pole-mounted transformers, bushings, conservators and individual barrels without oversizing.
Runs unattended
Once connected it completes the cycle on its own; a connection is provided for an optional vacuum controller that automates the process further.
Made to move
The 250 mm pneumatic tires, the 3 m power cord and two 3 m hoses with camlock couplings take the unit to the transformer, not the other way round.
Applications
- Oil processing in pole-mounted transformers.
- Bushings, conservators and other small oil volumes.
- Individual barrels of insulating or dielectric fluid.
- Periodic drying and degassing during maintenance.
About the product

Frequently asked questions
Which oils can it process?
Insulating and dielectric fluids in general: transformer oil in pole-mounted units, bushings, conservators and individual barrels of oil.
How dry does the oil come out?
With less than 10 ppm of water measured by Karl Fischer (ASTM D-1533 / D-1744) and less than 0.25 % of total gas content (ASTM D-831 / D-2945).
Does someone need to watch it?
No. The unit is designed for unattended operation, and an optional vacuum controller connected to the provided port automates the cycle.
Can it run on other voltages?
The standard configuration is 230 V, single-phase, 60 Hz; other voltages are available on request.
How is it moved around site?
On its own cart with 250 mm pneumatic tires; the 3 m cord and two 3 m camlock hoses connect it beside the equipment.
