The mobile oil station CMM-1,0 (hereinafter referred to as plant, unit, station) is designed for removal of solids and water from electric insulation oils, with viscosity not exceeding 70 cSt at 50 С.

The station can purify oil to purity class 9, starting from purity class 13 (mass content of contaminants no more than 0.004%) if the substance purified repeatedly passes through filtration block.

The plant is used during mounting, maintenance and operation of oil-filled high voltage equipment (power transformers, high-voltage switchgears, etc.).
