Known Models (5)
Alfa Laval EPC 50 OWS
5 m³/h
· Bilge Water
· Membrane OWS
medium: Bilge Water
type: Membrane OWS
Common Failures:
- • OCM sensor fouling giving false high readings
- • Membrane fouling
- • Auto-recirculation valve failure
- • Three-way valve stuck
Service: MARPOL Annex I. PSC hot topic — maintain oil record book. Clean OCM sensor weekly. Membrane replacement every 12-18 months.
Spares: Alfa Laval: O-Ring-Satz und Betriebswasserventil an Bord vorhalten. Lead time: 2-6 Wochen je nach Hersteller.
