Power supply

Industrial pumps and RO plants need a 3-phase 380/415 V, 50 Hz supply. Light valves and dosing pumps run on 220 V single phase.

Membranes and CIP

Membranes typically last 2.5–4 years depending on feed SDI and TDS. A chemical clean-in-place every 3–6 months restores flow.

Backwash and media

Backwash every 2–7 days depending on turbidity. Replace sand, carbon and softening resin every 18–24 months.

Brand, model, declared origin and available manufacturer documents are confirmed in the written quotation, with warranty stated per item.
