CJC® Thruster Filter
for gear oil and biodegradable lubricants
The own pump unit allows installation in a separate circuit (offline) and thus the continuous depth filtration and care of the gear oil (24/7).
In the ideal case,the pump sucks in the contaminated oil from the lowest point of the gearbox. But that is only possible with larger thrusters from certain manufacturers, as they have appropriate connections for installing an offline filter (see example 1). With this special connections the suction from the lowest point is also possible for thrusters with a rotation radius of 360 °C (azimuth etc.)
In all other cases, the pump sucks in the oil from the void space at the top, with the discharge either back to the same or to the header tank (see example 2). After oil filtration the oil is discharged either back to the void space or to the header tank (see example 2).
The CJC® Thruster Filter removes all impurities:
Water – free, emulsified and dissolved
for water content well below the saturation limit of the oil
(typisch < 500 ppm bzw. 0,05% — (typically < 500 ppm or 0.05% — in many cases, the CJC® Thruster Filter can reduce the water content even down to 0,1 %, but the rate of water ingress and the demulsibility of the oil play an important role)
Oxidation residues and acids
for persistent stable oxidation rate, TAN and TBN
Wear particles and suspended solids
Achieve cleanliness classes up to ISO 12 (ISO 4406).
Microorganisms
Prevent the spread of microorganisms with dry gear oil and efficiently remove existing microorganisms thanks to the high filtration degree and depth filter effect.
Due to their variety of combinations and modular design, the CJC® Thruster Filter and the integrated CJC® Depth Filter Insert can be optimally adapted to the specific conditions of the different thrusters and gear oils.
CJC® Fine Filter Inserts are depth filters with a filtration degree of 3 µm absolute and a retention rate of < 1 µm. The whole volume of the insert is made of numerous finely ramified fibres and offers an outer surface and, in addition, an inner surface – from 120 up to 150 m² per gram. That enables the extremely high dirt holding capacity – the higher, the longer the lifetime of the filter inserts.
The fact is that our dirt holding capacities are market leaders.
CJC® Thruster Filters can optionally be equipped with sensors for automatic online monitoring of the filter and oil condition. Depending on the selected system, you can select up to nine sensors – whether for oil moisture, oil temperature, particles (4-250 μm), wear particles (40-1,000 μm), oxidation rate, filter pressure and/or thruster utilization. You can configure alert limits and warnings to prematurely detect deviations from normal conditions and counteract them.
Our oil condition sensors provide detailed real-time data and allow conclusions about the thruster condition due to the high data density.
Our intuitive operable cloud applications have a clearly arranged dashboard to visualise the sensor data. The highly developed algorithms integrated into the premium monitoring package automatically evaluate and interpret the data – ideal for critical thrusters where failure quickly has costly consequences. Optionally, the sensor data can be transferred to your own system via various interfaces.
