"When the oil in a transformer reaches a stage (due to aging process) where purification / degassing is no longer efficient, the oil must be changed or regenerated. Regeneration is the complete treatment of oil to as new condition"

"Regeneration at the transformer can be carried out on line and contributes to Extended Transformer Life by removing acids & sludge's before they attack the chemical bonds which hold the cellulose insulation together. When the oil's neutralization number is as low as 0,05; the paper insulation is already being degraded and such degradation can not be reversed. Only Regeneration will remove sludge's & acids from out of the windings. If oil is replaced by new oil, impurities will leach from the winding & in a very short time the oil will be back to a poor state & degradation re-commences".

"Permasorb process offers Regeneration without the requirement to dispose of vast amounts of Fullers Earth - Environmentally Friendly & Safe process utilises permanently charged treatment columns offering some 3 years service before efficiency is effected & change of column charge is suggested".

March 2002 - FILTERALL launch "Retrofitting Solution" to replace existing old Fuller's Earth Dump Systems. Many existing Transformer Oil Purification processes have a separate Fuller's Earth Treatment facility which requires that the Earth be continually dumped and changed as it becomes saturated & no longer active. These systems are inefficient, labour intensive, expensive to operate and totally environmentally un-acceptable. Filterall offers Regeneration module utilising latest technology, which can be interlocked / incorporated into existing oil treatment system, to replace existing earth dump systems, reducing oil losses and eliminating requirement to dispose of contaminated Fuller's Earth. **For FILTERALL to design a modern updated Fuller's Earth facility for your existing processing plant, please provide following information:

1. Volume of oil to be treated in 24 hours
2. Dimensions of existing plant
3. General existing plant layout
4. General dimensions advising space available for retrofitting.

January 2002 - FILTERALL launched new range of compact Transformer Oil Regeneration Plant designed specifically to provide a commercially attractive solution for smaller transformers such as distribution transformers. Utilising existing Permasorb technology (as described in Specification S210 & S211) but with reduced capacities, the new mini compact plant can be supplied as a Trailer mounted Mobile unit or as a Stationary configuration, with or without a degasser system. The mini compact plants allow access to space restrictive areas (for example in city installations. High and consistent efficiency enables full Regeneration of Transformer Oil (be it in a transformer or in a single pass tank to tank situation) to BS148 / IEC296.
