Aging transformer oil forms sludge. Sludge attacks the cellulose insulation, inhibits oil flow, and traps heat inside the transformer. Eventually, the dielectric gap is bridged, resulting in the failure of the transformer.

Enviroflex Transformer Oil Regeneration Unit (TORU) removes acidity, sludge, and soluble oil decay products with Bauxite Sorbent. When the treatment is complete, the regenerated oil meets or exceeds international standards for new oil with lower acidity and improved tan delta, interfacial tension, and oxidation stability.

The cellulose insulation and internal components of the transformer also benefit from the flushing effect of multiple passes of hot reclaimed oil, which helps remove decay products and sludge from surfaces.

Regular regeneration treatments every eight to twelve years:

• Reduced risk of unplanned outage and costly downtime
• Reduced maintenance costs.
