   Mann + Hummel lube oil conditioning centrifuge system sales and service.


Oil is the life-blood of the engine and clean oil is essential if an engine is to operate efficiently throughout its working life. In response to environmental legislation and customer requirements engine manufacturers are adapting their designs to reduce harmful exhaust emissions and at the same time extend oil drain intervals. Emission reduction Technologies such as exhaust gas recirculation have been shown to increase the level of contaminant, especially soot in the lubricating oil. The net effect is modem oils are being required to work harder, last longer and contain ligher levels  of contamination. Therefore, advances in oil chemistry and filtration technology are essential to meet these needs.

Soot particles are sub-micron in size. Soot is a hard prowear particle. High soot levels within a lubricating oil have been shown to be responsible for accelerated wear of critical engine components. Traditional full flow and by-pass filters are unable to remove soot contaminant as it is too small to be effective at removing soot

Heavy durability engine test – oil analysis results displaying contaminant increase with engine operation hours. Engine size 8 litre, 250 kW Industrial Diesel The result concluded that the MANN + HUMMEL  centriguge controlled total contamination levels within the lube oil at a level below the engine manufacturers condemnation limit for more than double the standart drain interval.
