Maintain hydraulic oil of ME-Hydraulik, 2-stroke diesel engines | container ships
Customer Case
System: Marine Diesel Engines
Hydraulic control of the injection pumps and exhaust valves of the main engines (2-stroke diesel engines).
Engine: MAN 12K98 ME-C6
Oil type: Lubricating oil, Mobilgard 300
Viscosity: 111 cSt at 40°C
Oil volume: 16,000 liters
Container ship
Marine engine, 2-stroke, type MAN 12K98 ME-C6
Solution
Installation of a CJC® Hydraulic Filter 427/81 with CJC® Fine Filter Insert B 427/81 (3 µm absolute) for continuous fine filtration and dewatering of the hydraulic oil (24/7).
Dirt holding capacity: approx. 24 kg
Water absorption capacity: approx. 14.4 l
Filtration degree: 3 µm absolute, retention rate < 1 µm
Filter material: 100% natural fibres
The CJC® hydraulic filter removes particles, water, oil ageing products and acidic components from the oil with high efficiency.
CJC® hydraulic filters for marine engines installed on the MAN engine
Result
There have been no failures since installation. The convincing results of the filtration (see adjacent table) prompted our customer to install identical CJC® hydraulic filters on more than 24 ships of different classes up to 13,000 TEU.
