MCC & Electrical Power Containers

Containerised motor-control-centre, switchgear and power-distribution modules engineered for 50 °C ambient — the electrical heart of a remote hot-climate water plant.

MCC & Electrical Power Containers

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.

How We Build It for 50 °C

What our engineers specify on every unit of this type

  • Cooling sized for solar gain plus the MCC's own internal heat dump
  • IEC 61439 verified assemblies with documented temperature-rise design
  • VFDs rated to 50 °C ambient (external heat-sink option) to avoid current derating
  • Class H, 1.15 service-factor motors rated for high ambient
  • IP-rated, force-ventilated or air-conditioned, dust-filtered enclosure
  • Arc-flash-aware layout with safe maintenance access and isolation
  • Anti-condensation heaters in panels for the day/night cycle
  • Integration with grid / diesel / solar-PV / hybrid power per site

Frequently Asked Questions

Why does switchgear need a climate-controlled container?

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.

How is the cooling sized?

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.

Why specify 50 °C-rated VFDs and motors?

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.

Can it run on solar or hybrid power?

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.
