Engineering a Next-Generation Smart Controller for Industrial Heating Systems

From Legacy Interface to Intelligent Embedded Platform

A global manufacturer of induction heating equipment approached BWC Labs with a clear objective: modernize their machine interface while preserving the reliability and robustness their customers depend on.

Their existing standalone controllers were functional, but they limited scalability, operator efficiency, and future feature expansion. The client needed more than a UI refresh they needed a fully integrated embedded control platform that combined hardware innovation with intelligent firmware design.

BWC Labs delivered exactly that.

The Engineering Challenge

The engagement required rethinking the controller architecture across both hardware and software dimensions:

  • Replace legacy standalone controllers with a modern, touchscreen-based pendant system
  • Enable recipe-driven machine configuration to improve process consistency
  • Provide real-time operational feedback for improved control and visibility
  • Expand onboard memory to support advanced recipe management
  • Integrate a safety-compliant emergency stop (e-stop) circuit within the controller architecture
  • Ensure reliability suitable for demanding industrial heating environments

This required tight coordination between electrical design, firmware development, safety engineering, and user experience design.

BWC’s Embedded Engineering Approach

As part of our Embedded Systems practice, BWC Labs took complete ownership of the product development lifecycle:

1. System Architecture & Requirements Engineering

We collaborated with the client’s product team to define functional, safety, and performance requirements. The solution architecture was designed to support future scalability while maintaining deterministic performance.

2. Custom Hardware Development
  • Designed dedicated interface and display boards
  • Executed full PCB design and assembly
  • Integrated safety circuitry including e-stop
  • Ensured compliance-ready electrical design
3. Firmware & Embedded Software Development
  • Developed firmware in Embedded C
  • Leveraged NXP RT1024 Crossover Microcontroller
  • Built on MCU Xpresso development environment
  • Engineered optimized communication between interface board and display board
4. Human-Centric GUI Development
  • Designed custom touchscreen GUI screens
  • Implemented recipe-based navigation model
  • Structured user workflows to minimize operator error
5. Integrated Testing & Validation
  • Hardware-software integration testing
  • Debugging and performance optimization
  • System-level validation for industrial deployment
The Business Impact

The new smart controller became a foundational upgrade for the client’s product line.

  • Improved operator productivity through intuitive touchscreen workflows
  • Reduced setup errors with structured, recipe-driven control
  • Enhanced process repeatability across heating cycles
  • Strengthened safety with integrated e-stop design
  • Created a scalable embedded architecture for future product evolution

Beyond replacing hardware, BWC helped the client transition toward a digitally extensible embedded platform.
