HERING AMPS Adsorbent Mineral Polishing System has been created for customers that want a high-performance lube oil polishing treatment without using any chemicals or chemically activated substances, such as conventional bleaching clays. The AMPS re-refined oil polishing system is an ideal post-processing unit for oils that have been pre-treated by vacuum distillation or wipe-film evaporation. The key to the AMPS’ performance and environmental friendliness is the HERING PHÖNIX GREEN highly adsorbent mineral. This naturally occurring mineral has been enhanced by a physical process to lead to highest possible surface areas for maximum thermo-physical efficiency of the lube oil polishing process. HERING PHÖNIX GREEN has been specifically developed to replace conventional bleaching clays. It can be reactivated and reused up to 500 times in our HERING AMPS equipment before needing to be replaced. Our AMPS base oil polishing plant is a low operating cost and environmentally friendly alternative to other chemical re-refined oil polishing methods. The HERING AMPS rewards you with high quality group I and group II base oils.
