Recently, GN Solids Control has completed full factory test and acceptance for a custom‑built mud‑processing system, which will soon be delivered to an Africa‑based project. The technical highlight of this order is that all decanter centrifuges are equipped with self‑developed GN Smart Control VFD variable‑frequency control cabinets. This intelligent control core copes with challenging site conditions in Africa including variable feed material, limited on‑site maintenance staff, high ambient temperature and heavy dust, and delivers reliable continuous‑run performance for mud treatment and drill‑cuttings dewatering.
Built on PLC‑HMI platform with multi‑language interface support, GN Smart Control VFD cabinet can dynamically adjust bowl speed and scroll differential speed according to real‑time mud density and viscosity. Interlocked control between feeding pumps and centrifuges is realized. Integrated functions cover vibration monitoring, temperature detection, overload protection, fault pre‑alarm and historical‑data logging. Compared with conventional fixed‑speed control panels, GN Smart Control VFD reduces commissioning workload and manual intervention, optimizes energy consumption and eases on‑site maintenance, perfectly fitting African site operation requirements.

All equipment has been upgraded for harsh African climate with enhanced electrical protection, anti‑corrosion treatment and optimized wear‑part configuration. Full unit test and system joint commissioning are finished prior to shipment to enable quick start‑up upon arrival.
Full scope of supply for this Africa project:
10 units GNLW453D‑VFD large‑bowl decanter centrifuges with support skids
5 sets GNCD930G cuttings dryer systems
10 sets feeding pumps
10 sets screw conveyors Other complete auxiliary accessories
This package forms a complete workflow from material feeding, centrifugal separation to enclosed solid discharge. GNLW453D‑VFD large‑bowl centrifuge delivers high‑throughput solid‑liquid separation. GNCD930G dryers achieve deep dewatering for drill cuttings. Feeding pumps guarantee stable inflow, while screw conveyors transfer dewatered solids in enclosed mode. All units work in coordination for non‑stop site operation.
This bulk export order demonstrates overseas customer’s recognition of GN’s mechanical performance as well as in‑house GN Smart Control intelligent control technology. GN will keep supplying integrated separation equipment and smart control solutions for global oil‑gas, mud‑treatment and environmental‑protection projects.
