Deoiling systems for marine (bilge), oil & gas (process, brine, injection) and power‑generation (process, cooling) applications that separate oil–water mixtures to meet regulatory discharge limits (IMO MEPC.107(49) 15 ppm and equivalent 15/5 ppm approvals); capacities 250 l/h–10 m3/h. Modular fuel‑treatment units for middle distillates and lubricants using filter‑coalescer and optional 5 μm polishing, fully automatic water discharge and differential‑pressure control, max water content 70 ppm; capacities 200–7000 l/h, offered as a centrifuge alternative.
