CMM 4/7 is designed for transformer oil purification. It can efficiently remove water, gasses and solid particles. The main feature is that the unit is able to clean oil while directly connected to a working transformer. It helps to improve oil dielectric strength and save money on buying a new one. Production capacity is 4 tons per hour in degassing mode (with heating) and 7 tons per hour in heating mode (without degassing). CMM 4/7 is a best solution for power generation/distribution companies, electrical contractors and waste oil treatment companies.
