Can I use a diesel purifier machine for transformer oil cleaning?

Diesel purifier machines are not suitable for transformer oil. They typically use water separation and coarse filtration only. Transformer oil requires vacuum degassing, fine filtration (5-1 µm), and moisture removal down to ppm levels. Using the wrong system can damage the transformer. Fluidex machines are purpose-built for insulating oil and comply with BDV, TAN, and moisture content specifications.
