How it works
How it works
Separator technology and the ALCAP™ advantage
High-speed centrifugal separators clean marine fuel by removing water and particulate matter. Traditional separator designs use a gravity disc that is manually adjusted depending on the density of the specific fuel being used.
Alfa Laval’s ALCAP™ separator technology eliminates the gravity disc to allow for automatic adjustment to fuel density. In multifuel operations, ALCAP™ provides the advantages of uninterrupted operation, improved fuel efficiency, and maximum separator performance and engine protection.
The Alfa Laval S separator, with ALCAP™ technology, features software that allows you to set parameters in the process controller. This lets you combine heavy fuel oil and lubricating oil treatment in a single separator. After centrifugal separation, the clean oil is continuously pumped away. Water and sludge accumulate at the bowl periphery.
A water transducer in the clean oil outlet measures capacitive resistance and signals changes to the EPC60 control unit, which masterminds the system. Depending on the water content, the EPC60 either opens the drain valve or expels the water during sludge discharge.
The CentriShoot discharge process uses a patented slide that eliminates metal-to-metal wear and minimises loss compared to other systems.
The Alfa Laval P separator is designed for well-defined oils with fewer process issues. The separator bowl has manually set gravity discs to deliver high performance but does not automatically compensate for process fluctuations. The separator bowl can be configured as a purifier or as a clarifier.
- A purifier removes solids and water from oil.
- A clarifier is removing only solids (no water) from oil.
The Alfa Laval S separator equipped with proven ALCAP™ technology, features advanced software for precise parameter setting via the process controller. This flexibility enables you to treat both heavy fuel oil and lubricating oil in a single separator module. After centrifugal separation, clean oil is continuously pumped away, while water and sludge collect at the bowl periphery.
A water transducer in the clean oil outlet measures capacitive resistance, instantly signalling any changes to the control unit. The controller then manages the system, automatically opening the drain valve or expelling water during sludge discharge, based on real-time water content.
The CentriShoot discharge process utilizes a patented slide mechanism, eliminating metal-to-metal wear and minimizing oil loss—delivering efficient, reliable performance with every cycle.
The Alfa Laval P separator is engineered for well-defined oils and straightforward process conditions. Its separator bowl uses manually set gravity discs to achieve high performance, though it does not automatically adjust for process fluctuations. Depending on your needs, the separator bowl can be configured as either a purifier or a clarifier.
- A purifier removes both solids and water from oil, ensuring comprehensive cleaning.
- A clarifier is dedicated to removing only solids, with no water separation.
