Why use off-line oil filtration systems from C.C.JENSEN?

Off-line filtration or kidney loop filtration delivers similar- or better-quality oil compared to a conventional separator. C.C.JENSEN offers new technology in filtration systems that revolutionizes the way lube oil is maintained on two- and four-stroke engines across all fuel types. As a global authorized partner of C.C.JENSEN, we are offering the CJC engine lube oil filtration systems, tested by MAN PrimeServ, to prolong the service life of your engine, reduce maintenance costs, and improve environmental performance.

Benefits of installing a C.C.JENSEN lube oil filter:

Main benefits compared to a conventional separator

  • Up to 60% less oil consumption on four-stroke engines
  • Up to 20% less oil consumption on two-stroke engines
  • 99% lube oil sludge reduction
  • 97% fuel savings compared to a conventional separator, contributing to the CII*
  • Extended oil and component lifetime by 2-10 times
  • No preheating of oil is required

Additional benefits:

  • ROI under 1 year
  • Cost-efficient and easy maintenance
  • Off-line system does not require the main system to shut down for maintenance or filter changes
  • Continuous cleaning 24/7/365
  • Controlled oil replacement on schedule

Testing oil and engine condition

Quick test: efficient oil care

The quick test shows that the lubricating oil was heavily contaminated with dust, metal abrasion, and other particles before and at the beginning of the test period. Oil aging signs and high water content were detected. Thermal load on so-called hot spots (e.g. bearings) and particles from component wear (copper, iron, aluminum) accelerate the degradation of the base oil as well as of the additives and thus the oil aging process.

With the efficient oil care from the C.C.JENSEN filtration system, particles, water, oil aging products, as well as acid compounds were permanently removed. The oil cleanliness throughout the test period has been significantly improved.
