ALCAP separators are used for purifying oil of specific gravity more than 0.991.
When oil is fed into the system through the oil inlet, the separated water and sludge accumulate at the bowl periphery.
The purified oil is discharged through the oil outlet.
It operates similar to clarifier.
However, the separator uses a flow control disc instead of the standard gravity disc, as the difference in specific gravity between the water and the fuel oil to be purified is less.
A water transducer is situated on the oil outlet side.
It senses the water content and activates the control unit.
When the accumulation of seperated water increases, the water approaches the disc and part of the water is carried over with the clean oil.
The water transducer senses the water in the oil and sends a signal to the control unit.
The control unit opens the water drain valve.
The accumulator water flows through the hole in the flow control disc and drains through the valve.
The accumulated water can also be removed through the sludge port along with the sludge during desludging.
The control unit is programmed to keep track of the number of times drain valve opens and the time elapsed after the last desludge cycle.
Accordingly, the control unit drains the water through valve, or by desludging.
