Cee dee vacuum equipment provides electrostatic oil cleaners [model cdoc-50] the most optimum machines for cleaning the used/contaminated oil. These oil cleaners are capable of removing contaminants of size as small as 0.01 micron and cleaning the oil up to nas level 4-5, ie, better than new oil [new oil nas level is nas 9-12], giving trouble-free operation and maintenance free units. These systems use electrostatic precipitation to remove sub-micron particles of insoluble material, without effecting soluble oil additives. Tiny particles are electrostatically driven to, and then captured on, the positively or negatively charged walls of electrodes. Large particles are trapped in the resin impregnated cellulose filter. The oil cleaner machines are state-of-the-art product available with unique and latest features, which doesn`t require attendance during operation. The machines come with special dehydration attachment capable of removing moisture/water contents up to 5,000 prm compared to any other brand limiting them to only 500 ppm. Oil tanks are designed cylindrical with stainless steel construction instead of conventional rectangular shape to ensure faster cleaning rate and less power consumption, also reducing the downtime of machine for replacement of filters. Complete operation of the machine is handled by plc with 2-line alphanumeric display.
