Commodity Chemicals for Fishing & Marine in Namibia

Hot caustic solution dissolves the fish oils and proteins baked onto evaporators, cookers and lines — the only chemistry that genuinely restores heat-transfer surfaces in that service. Circuits typically run 1–2% hot, with periodic acid descaling underneath because coastal boiler water layers mineral scale under the organic soil.

Buy fresh and often: hypochlorite loses strength in heat, and a drum stored beside a cooker room doses weaker every week. Weekly or fortnightly deliveries from our coastal stock — rather than a quarterly inland order — keep dosing honest. Never mix it with acid products anywhere in the plant; that rule belongs in induction training.

Namib fog is salt-laden and persistent — caustic, soda ash and calcium chloride pull that moisture through any opened bag within weeks. Order pack sizes you consume quickly, reseal into drums with lids, store off the floor, and accept that coastal stores need faster turnover than inland ones. Our delivery cadence is built around exactly that.

Caustic or soda ash lifts acidic streams; where the swing is the other way, acid dosing from our range trims it back. Metabisulphite handles residual-chlorine neutralisation after sanitation cycles. We supply the pH test kit alongside so the correction is measured, not guessed — discharge complaints in a working harbour are neighbours you meet again.
