The first HERING transformer oil purification plant was built in 1909. Today, we are offering transformer oil purification machines, transformer oil regeneration systems, PCB dechlorination equipment and customized oil treatment solutions.

Vapor Phase Drying is classified as the most efficient industrial drying process for power transformers and tap-changers which, at the same time, has the least impact on the material. Under vacuum, moisture is removed from the insulation system.

The HERING AMPS Adsorbent Mineral Polishing System enhances color, odor and the chemical properties of recycled base oils through our thermo-physical lube oil polishing treatment – without using any bleaching clay.
