S and P Flex

Features

Flexible, modular system

Configure and integrate compact separation systems with ease. Choose between loose components or assembled modules, mixing and matching separator types, separator sizes, ancillary blocks and skids. All to match your needs and space.

Biofuel ready

Operate confidently as you decarbonize, despite the added challenges posed by biofuels. The S and P Flex range is compatible with HVO (EN 15940) and FAME (EN 14214 or ASTM D6751) blends comprising HSFO, VLSFO and/or distillate oil.

Adaptive ALCAP™ technology

Choose an S separator to maximize protection – and to keep oil losses to an absolute minimum. S separators use ALCAP technology to adjust automatically to oil density and viscosity. That means reliable, efficient cleaning of even unpredictable fuels.

Low operating costs

Avoid not only oil losses and large sludge volumes for disposal – but also maintenance costs. Besides cleaning with high efficiency, S and P separators share a mechanical platform that reduces wear and extends service intervals.

CentriShoot discharge system

Avoid waste and wear during discharge. The CentriShoot system in S and P separators works quickly and precisely, minimizing oil losses. Its fixed discharge slide flexes gently to expose the discharge ports – without any metal-to-metal contact.

CentriLock bowl-locking system

Make service work fast and hassle-free. In S and P separators, the bowl is held in place by a lightweight CentriLock snap ring. The non-threaded ring snaps into place and lifts out easily, providing rapid access that keeps maintenance simple.

How it works

Your choices, configured your way

The S and P Flex range combines leading separation technology with a flexible scope of supply. The flexibility begins with two separator types: S and P. While they share a high-performance mechanical platform with wear-reducing features, the resulting separation systems are suited to different applications.

S separation systems – for hard-to-clean oils with varying properties

S separation systems feature ALCAP™ technology, which lets them adapt to the oil being cleaned. They ensure optimal performance and robust engine protection.

When water enters the disc stack, the ALCAP function detects it and automatically activates the drain or discharge mechanism. This maintains optimal separation when using oils with varying densities and viscosities. The result is effective removal of cat fines and other impurities, with only a minimum of oil lost as sludge.

Because they adapt automatically, S separation systems are the best choice for unpredictable residual fuel oils. Likewise, they are the best choice for biofuel blends containing HSFO or VLSFO.

P separation systems – for well-defined distillates and lube oils

Alfa Laval P separation systems are the go-to choice for cleaning scenarios with stable and predictable oils. Based on purifier technology, they use a gravity disc to set the separation point and regulate water removal.

Because the adjustment is manual rather than automatic, P separation systems are intended for distillate and lubricating oils that have known and limited densities. They are compatible with biofuels, just like the more versatile S separation systems. But they should preferably be used with well-specified FAME or HVO, which should only be blended with distillates.

Understanding the ALCAP™ advantage

Take a closer look at the adaptive ALCAP technology used in S separation systems, which automatically adjusts to changing oil density and viscosity. This film explains how it differs from the gravity disc technology in P separation systems – and why it matters when using residual fuels or biofuel blends that contain them. When the oil is less predictable, ALCAP means peace of mind.
