Weimiao Delivers Industrial Control Cabinet for Water Treatment Plant Machine Room
Weimiao designed and delivered a custom PLC control cabinet for a municipal water treatment plant.
Built for the main machine room, the cabinet integrates international-grade electrical components with IP-rated sheet metal housing—engineered for high humidity and continuous operation. It supports automation of flow regulation, pump control, and system safety with UL-compliant wiring and smart internal routing.
Equipped with International-Grade Electrical Components
To ensure maximum reliability and global compliance, the cabinet incorporates a wide range of world-class electrical components from leading manufacturers. Explore more of our PLC control cabinet projects to see how Weimiao integrates global brands across different industrial applications.
Key components include:
Mitsubishi FR-A840 Inverter – advanced frequency control for motor-driven systems
ABB SACE Circuit Breakers – overcurrent and short-circuit protection
ABB Isolators and Disconnectors – for safe equipment maintenance
ABB TA Series Breaker Protectors – thermal and magnetic trip protection
ABB AC Contactors & Thermal Overloads – for start-stop motor control
Temperature Monitoring Relay – to prevent overheating in high-load circuits
Phoenix Contact Terminal Blocks – modular wiring and safe signal connection
All components are professionally installed inside the enclosure with UL-standard wire terminations and fire-retardant ducts. Similar multi-brand integrations can also be found in our PLC control cabinet with multi-inverter system project, where VFD-driven automation is applied in water and wastewater treatment environments.
Built by Weimiao – From Sheet Metal Fabrication to System Integration
As with every Weimiao project, this cabinet was 100% custom-designed and fabricated in-house at our ISO 9001:2015 certified facility. Learn more about Weimiao’s sheet metal fabrication and control panel manufacturing capabilities across global industrial projects.
Cabinet design highlights:
IP-rated, powder-coated enclosure suitable for industrial humidity
Optimized internal space for VFD, MCC, and thermal control zones
Laser-cut panels, CNC-bent frames, and reinforced base plates
Pre-mounted DIN rails, busbar supports, and terminal labeling
Structured cable pathways with separation between power and control circuits
All equipment is subject to our multi-stage QA process, including high-voltage testing, thermal simulation review, and electrical insulation checks—ensuring long-lasting performance and operator safety.
Full Engineering Support and International Installation Readiness
Weimiao provided full technical support throughout the project lifecycle, including:
Design consultation based on the client’s electrical schematics
3D layout validation and installation compatibility review
Assembly drawings and terminal block layout documents
Pre-labeled wiring, BOM traceability, and UL-compliant documentation
Shock-proof export packaging and real-time video guidance for installation teams
This project reflects Weimiao’s continued commitment to supporting global water infrastructure projects. You may also explore our international industrial control cabinet projects to see how we support overseas installation teams with drawings, documentation, and real-time guidance.
