1 !"#$"! NEPHRON SYSTEM Protect engine Save resources Protect environment Save money

2 NEPHRON is the very special oil recycling system. It enables it to use LO permanently. This is an important factor in maintaining engine performance. Economy of the the operation and reliability of the engine will be improved because the time between overhaul and life of engine parts will be prolonged. The Nephron is a system which maintains engines performance at optimal efficiency.

3 NEPHRON always keep LO clean as the kidney of animals keeps their blood clean. It is therefore called kidney system

4 NEPHRON is able to remove LO sludge soon after generated Nephron system There is no need of oil renewal forever and it is enough to supply only a small amount of fresh oil sometimes to compensate for the consumed oil. No waste oil is, therefore generated in the Nephron system. Diesel engine

5 Protect engine Save resources Protect environment Save money %&Nephron is a system which maintains engines performance at optimal efficiency. %%&Nephron protects the earth from pollution and keeps resources from being wasted. %&Nephron enables it to use lubricating oil(lo) permanently without waste and reduces LO consumption.

6 More than 1000sets of NEPHRON supplied Nephron system has been working well in more than 1000units of marine and cogeneration diesel engines and in many hydraulic machines for many years. The results also shows that the technology remarkably improves reliability of machines.

7 Difference of mechanism of the filtering Conventional type filter contaminated LO flows through the filter meshes and only large sludge particles can be caught. In case of the Nephron system, many sheets of paper are arranged parallel and contaminated LO flows between the filter paper sheets. Then sludge particles sit on the surface of the filter paper and they are easily removed from LO.

8 AS the result of keeping LO clean, following merits shall be obtained 1) No oil renewal and No waste oil 2) Reduction of LO consumption 3) To minimize the wear of engine and parts 4) Improvement of engine reliability due to clean LO

9 Comparison between NEPHRON and conventional system Nephron system

10 Keep LO clean under the Normal pentane 0.1% The data below shows the condition of the Normal pentane (n-p) insoluble. The figure of three systems except kidney system increasing rapidly. Only the Kidney system enable the LO keep clean under the 0.1% level.

11 Causes of re-gradation LO is not oxidation but the contamination of sludge particles

12 Sludge particles of up to 1µ diameter in the lubricating oil can now be filtered out.

13 Optimum contamination level of LO Under using Nephron, there have been very little wear of piston ring, liners and bearing metals in the engine. So Engine must be operated within the yellow band to keep good performance and optimal efficiency, which shows optimum contamination.

16 LO consumption could be reduced 1400PS Generator Engine (Diesel)

17 Maintenance interval could be prolonged

18 Maintenance cost could be reduced!conventional system'' (Nephron system Cost per month Cost for Parts Productivity Cost for Repair NAS class Economical Merit by Nephron system

22 NEPHRON can be applied whole types of the diesel engine from small to the huge marine main engine.

23 NEPHRON acts much like a kidney, flitting out foreign particles from the engine LO. Nephron filters Oil tank Heater Centrifugal separator Engine

25 NEPHRON system is consisted by Centrifugal separator and Special filter

26 Example of the supply for Tanker

27 %&100L of LO can be cleaned by Nephron filter %*pplied for Small class engine / 100kW5300kW %6sed For marine and generator engine

28 %&600L of LO can be cleaned %*pplied for Middle class engine / 500 kw51250kw %6sed For marine and generator engine Centrifugal separator

29 %&1200L of LO can be cleaned %*pplied for Large class engine / 1000 kw53500kw %6sed For marine and generator engine

30 Three types of Centrifugal separator 1) Manual maintenance type 2) Semi automatic maintenance type 3) Full automatic maintenance type
