Service: ALCAP mode for LO; lower throughput than FO mode; maintain clean disc stack.

Spare Parts: Alfa Laval: O-Ring-Satz und Betriebswasserventil an Bord vorhalten. Lead time: 2-6 Wochen je nach Hersteller.

Strengths

High separation efficiency with very low oil loss (typical <0.1 % per pass)
Robust disc‑stack construction; EPDM sealing rings give long leak‑free service life
Compact footprint suitable for engine rooms of medium‑size vessels
Standardised maintenance intervals (seal replacement 6‑8 k h, bearing change 12‑16 k h) and clear inspection points
Proven Alfa Laval brand reputation and worldwide support network

Weaknesses

LO mode provides lower throughput than the FO (fuel‑oil) variant; may be undersized for very high‑power engines
Disc stack must be kept clean – frequent inspections are required to avoid erosion or fouling
Maximum sludge volume is limited; excessive contamination can cause rapid pressure rise and reduced efficiency
Bearing and seal replacements still require engine‑room shutdown periods
No built‑in heating; oil temperature must be managed externally in cold climates

Typical Vessels: TankerBulk carrierContainer shipCruise linerOffshore supply vesselNaval auxiliary ship

Decision Guide: Choose if you need a reliable, space‑efficient lube‑oil purifier with proven Alfa Laval service support and can accept the lower LO throughput. Avoid if your propulsion plant demands very high oil‑flow rates or if maintenance access to the disc stack is severely restricted.
