Instrumentation & Control (I&C) Containers

Climate-controlled, dust-sealed control and analyser containers housing the PLC, SCADA, instrumentation and analysers that run a remote hot-climate water plant unattended.

Instrumentation & Control (I&C) Containers

Container type — in the hot-climate programme

The control system is the brain of an unattended plant, and electronics are the least heat-tolerant things on site. Mainstream PLCs (Siemens S7-1200, Allen-Bradley CompactLogix) are rated to a 60 °C cabinet, but at a 50 °C ambient with internal heat gains the cabinet reaches that limit fast — so the instrumentation & control container is built around keeping the electronics cool, clean and powered.

We house the PLC, SCADA/HMI, telemetry, marshalling and online analysers in a fully insulated, positively-pressurised, air-conditioned container with N+1 cooling and anti-condensation control. Cabinets are IP-rated, dust-filtered and arranged for serviceable airflow; analysers (pH, conductivity, turbidity, chlorine, ORP) sit on a sample-conditioning panel so a technician can calibrate in comfort rather than in the heat.

Because control availability is as important as the process itself, the I&C container carries the redundancy that keeps supervision alive — UPS-backed controllers, resilient telemetry and, where required, functional-safety instrumented systems to recognised standards.

Configurations & Variants

Built to the duty, to one hot-climate standard

How We Build It for 50 °C

What our engineers specify on every unit of this type

  • N+1 air-conditioning to hold the cabinet below the PLC's rated limit at 50 °C ambient
  • Positive pressurisation and F7-grade filtration to keep dust off boards and heatsinks
  • Anti-condensation heaters and managed airflow for the day/night cycle
  • UPS-backed controllers and telemetry for ride-through and graceful shutdown
  • IP-rated, serviceable cabinets with documented internal layout
  • Sample-conditioning panel so analysers are calibrated in comfort
  • Ruggedised PLC option (Schneider Modicon M580) where HVAC redundancy is not enough
  • Functional-safety instrumented systems to IEC 61508/61511 where required

Frequently Asked Questions

Why does the control system need its own container?

Because electronics are the least heat-tolerant equipment on a hot-climate site. A dedicated insulated, air-conditioned, dust-sealed container keeps the PLC, SCADA and analysers within their rated cabinet temperature and clean of dust — which a process container cannot guarantee.

What stops dust reaching the control panels?

The container is sealed and held at positive pressure with filtered make-up air, so any leakage is outward. The same F7-grade filtration and positive-pressure principle protects the MCC and welfare containers.

How is control kept available if power dips?

UPS-backed controllers and telemetry ride through short interruptions and shut down gracefully on a prolonged one, while resilient cellular or satellite store-and-forward telemetry keeps supervision and data intact for an unattended site.

Can analysers be calibrated on site comfortably?

Yes — online analysers sit on a sample-conditioning panel inside the cooled container, so a technician calibrates pH, conductivity, turbidity and chlorine instruments in a controlled environment rather than in the heat and dust.
