Des-Case Corporation manufactures customizable filtration solutions for all industry applications, including innovative dedicated filtration kits specifically tailored for mobile equipment. One such system, the ENG-2, was installed to filter the engine oil.

The Des-Case ENG-2 mobile equipment engine kit provides filtration with depth media for a constant contamination control solution at very low ISO cleanliness levels. The system works by taking approximately 10% of the oil flow after the OEM full flow filter and directing it through the ENG-2 system. Oil flows through the canisters at a set rate and is returned directly to the engine sump. The system is designed to prevent the canisters from being emptied when the equipment is shut down, while the small amount of oil directed through the ENG-2 system at any given time ensures the engine is never starved of oil. A pressure relief valve is also installed to prevent accidental over pressuring of the canisters during cold cranking.

The ENG-2 is a depth type secondary (slip-steam) filtration system. The system is designed to meter engine oil flow through the filters at ½ GPM. This slow flow rate, combined with the depth filtration, allows the system to have significant impact on soot and particles less than 1 micron in size.

Target cleanliness targets at the time of installation were established at ISO 19/17/14 (c) which, compared with the engine oil cleanliness prior to installation of ISO 22/21/18 (c), should yield a sixteen-fold reduction in particle contamination within the engine, resulting in a projected three-fold extension of the engine life.
