Senior C/E, Scandlines, Henrik Fald Hansen:
„The installation of the CJC oil filter has been an absolutely positive experience. The quality of the oil is as good as it was before, well, actually better in all aspects. The appearance of the oil has changed from dark to light and looks like new oil.
We are saving person-hours and chemicals we used to clean the centrifuge and have less of a mess in the engine room. We are saving on sludge production. The centrifuge is discharging every hour. For cleaning, we use displacement water. The oil loss generated during centrifugation contaminates the water. The formed sludge consists of approx. 0.2 litre of oil (oil loss) and approx. 2.5 litres of water (cleaning) and goes directly into the sludge tank. With 8,700 discharges annually, this corresponds to 1,740 litres of oil and 21,750 litres of water. The costs to dispose of the sludge amounted annually approx. EUR 2,013.
On top of that, we are saving a lot of lube oil. The oil loss during centrifugation and when the centrifuge fails amount to approx. 2,500–3,000 litres annually. At the cost of approx. 1.34 EUR per litre, we save 3,356 – 4,027 EUR each year.
In all aspects, a good investment, and if we are not switching to battery / electrical propulsion, we will definitely also install oil filters on engines DG1 and DG2.“
