QMJ Series Varnish Removal Oil Purifier is mainly used to remove the dissolved and suspended soft pollutants in turbine oil. So-called soft pollutant is oil varnish’s precursor which is caused by systems’ hotspot such as bearings and pumps. The existing forms of the soft pollutants are dissolved and suspended, while these soft oxides removal can avoid oil varnish generation. Once oil varnish forms, machinery fault or boot failure by valves adhesion and out of control occurs, clogging and limitation of flow leads to oil temperature rising and increased abrasion, attachments on sandpaper surface increase element’s wear rate, disabled heat exchanger lifts oil temperature, stoving varnish formed on bearings and limitation of low increases abrasion and temperature, and frequent oil replacement and system washing. When the soft pollutant dissolves in oil, the typical oil temperature situation overtops 40℃, then normal mechanical filtration shall be disabled.
