Clean Oil Technology (COT) reduces effectively free and dissolved water from the oil with its unique technology – to PPM-levels well below 200 PPM and sometimes below 100 PPM. It keeps the water content at a constant very low level. A particle filter with water absorbing capability can also be included in the scope of supply in case of momentarily high water content. COT doesn’t require any maintenance or service as in changing a water absorption filter. Also, no disposal of waste products.
