The S.I.T CD-SR "Sludge Reduction" System

Either
CD-SR InLine for direct Purifier Service

or
CD-SR TC for permanent Circulation of Settling Tank Content

 
How:

For standard installation (also for retrofitting purposes) the respective CD92™ Mycronizer should be installed in-line between the purifier heater and the purifier, because the CD92™ requires a fuel temperature of min. 70°C for reliable operation.
The advanced installation (best possible on newbuildings) requires free suction and discharge connections at the FO-Settling Tank, where the CD-SR/TC Module is connected to. The CD-SR system now can be operated independent of any operational deviations at constant conditions. This installation also requires min. 70°C fuel temperature in the tank.

Function Principle :
Achieving all the advantages of conditioned fuel requires the adjustment of the flushing sequences of the purifiers. Caused by the entire homogenous structure of conditioned fuel, with a majority of fuel droplets below 3 micron size (> 95%) the fuel is passing the purifier full stream. When now the flushing sequence remains at eg. 30 minutes (48 flushes/day) the entire content of the bowl will be discharged to sludge tank, without necessity. Valuable fuel will be wasted. Extension of flushing sequence to maybe 120 minutes (just 12 flushes/day) will reduce the sludge amount to just 25% of conventional amount. Experiences are stating, that also 180 minutes (just 8 flushes/day) are possible without any side effect.
