Containerised motor-control-centre, switchgear and power-distribution modules engineered for 50 °C ambient — the electrical heart of a remote hot-climate water plant.
Container type — in the hot-climate programme
Every pump, blower, VFD and dosing unit on the plant draws from the motor control centre, and switchgear hates heat: breakers and contactors derate, busbars run hotter, and a 40 °C-rated panel in a 50 °C container is operating outside its design. The MCC & power container is built so the electrical distribution keeps its rating in the worst ambient the site presents.
We house the MCC, distribution boards, VFDs, transformers and (where used) the generator-control and ATS in an insulated, force-ventilated or air-conditioned container with the cooling sized to remove both the solar gain and the considerable internal heat the equipment itself dumps. Panels are built and verified to IEC 61439, IP-rated against dust, and laid out for safe access and arc-flash management.
VFDs and motors are specified with hot-climate headroom — 50 °C-rated drives and Class H, high-service-factor motors — because standard ratings derate sharply in desert heat. The container ties into the wider power strategy, whether grid, diesel, solar-PV or hybrid, designed on the power-systems page.

| Standard | Scope | Why it matters |
|---|---|---|
| ISO 668 / ISO 1496 | Container dimensions & specification | ISO series-1 freight-container form factor and strength |
| ISO 1161 | Corner castings | Standard lifting/securing points for crane and twist-lock |

| IEC 60529 | IP ingress protection | Dust/water rating of the enclosure and entries |
| IEC 61439 | LV switchgear & controlgear | Verified MCC/distribution assemblies |
| IEC 60204 | Electrical equipment of machines | Safe machine electrical design |
| ATEX / IECEx | Hazardous-area rating | Where flammable atmospheres are present |
Because breakers, contactors and VFDs derate in heat and a standard 40 °C-rated panel is outside its design at 50 °C. An insulated, cooled, dust-sealed container keeps the MCC within rating and protects it from the dust that causes tracking and overheating.
To remove both the external solar gain and the substantial internal heat the MCC, transformers and VFDs generate themselves. Sizing on ambient alone under-cools the container; the equipment heat dump is the larger load and is designed for explicitly.
Because VFD output current derates roughly 1–2% per °C above its rating and standard motor windings lose around 30% capacity at 55 °C ambient. Specifying drives and Class H high-service-factor motors with hot-climate headroom keeps the plant at full duty.
Yes — the MCC container integrates with grid, diesel, solar-PV or hybrid supplies, with generator control, transfer switching and UPS as required. The overall power strategy is sized on the hot-climate power-systems page.
