Benefits of installing CJC® Filtration
- Reduce risk of off-hire
- Optimise efficiency of the tug
- Reduce risk of stern tube repairs, unplanned breakdowns and emergency dockings
- Protect your investment
- Reduced maintenance oil replacement costs
When you install a CJC® Oil Filter solution on your stern tube system, you get an oil filter with excellent water, dirt and oxidation removal capacities, and the highest dirt holding capacity.
The propeller seals and bearings are at risk of being damaged if the oil is not kept free from seawater, particles, and oxidation residues. Water ingress happens through propeller seals due to damage wear, and movement of the shaft. Seawater causes corrosion and increases wear rate on bearing and seals. Sand and silt can cause abrasion in vessels operating in shallow waters. For some Environmentally Acceptable Lubricants (EAL), water contamination can even result in acids in the oil, and replacing all oil in the system is very costly. Worst case, you lose manoeuvrability of the tug and risk losing charter

HDU Fine Filter
Desorber
CJC® Fine Filters are offline oil filtration solutions with integrated circulating pumps for off-line installation. The filters are recognized around the world as highly efficient purification systems for applications involving hydraulic oil, lubrication oil, gear oil, quenching oil, phosphate esters and more.
CJC® Fine Filters are ideal for controlling oil contamination levels for particles, water and degradation products (oxidation resin/sludge, varnish).
CJC® Desorbers are patented products designed to remove water from oil types which either bind and emulsify water or are high viscosity oil (up to ISO VG 1000). CJC® Desorbers are ideal for use in applications in which water ingress is a continuous and significant problem, whether for lubrication oil, gear oil or hydraulic oil.
CJC® Desorbers heat oil slightly before it meets a counter flow of cool air in the desorber housing. Air heated by the oil expands, drawing water from the oil. The subsequent air-cooling condenses the water and the dry air is re-used for removing water from incoming oil.
