What equipment do you recommend for on-site transformer oil purification and regeneration, and what are the key parameters to control?

For on-site transformer oil purification and regeneration the recommended choice is the CMM-12R oil regeneration system: it’s designed specifically to regenerate and degas transformer insulating oil (including operation integrated with or adjacent to a transformer and in some configurations while energized), delivers long-lasting sorbent performance, and can be customized with remote control, moisture meters, extra vacuum capacity and a climate-controlled operator cabin. In practical terms the CMM-12R will reduce moisture content to very low ppm levels, lower acidity and restore dielectric strength toward new‑oil values, and its sorbent can often be reactivated in the field rather than replaced, which lowers lifecycle cost.

For smaller sites or tighter budgets consider the CMM-6RL (compact, sorbent-based regeneration, ~0.45 m3/h in the transformer variant) or the CMM-8LT when higher throughput (about 8 m3/h) with heating, drying and degassing is required. For mobile traction-transformer work the CMM-600CF gives multi-stage filtration, dehydration and degassing at roughly 600 L/h and can include online humidity monitoring (TOR-5). If you want to run on-site lab checks before committing to a field unit, use the CMM-0.001U laboratory filtration unit for controlled testing. Tell me your site scale, required throughput and whether you need mobile or fixed equipment and I’ll recommend the best configuration and key options (degassing/drying modules, vacuum pumps, moisture monitoring, sorbent reactivation) for your workflow.
