Industrial Conveyor Heater Control System
A high-power industrial heater controller designed for conveyor-based drying and heat treatment systems. The platform provides independent PWM control of four heating zones through Solid State Relays (SSRs), allowing precise temperature regulation for industrial drying ovens, silk screen curing, and heat-shrink production lines.
Project Overview
This project is an industrial Heater Control System developed for Dynamic Screen Printing Solutions to automate heating processes in conveyor-based thermal systems. The controller is used in industrial drying ovens for silk screen curing, heat-shrink packaging, and other continuous heating applications where stable temperature and precise timing are essential.
The system combines power control, timer management, and an intuitive touch interface into a reliable industrial controller designed for long operating hours.
Client Requirements
The client needed a compact industrial controller capable of:
- Controlling four independent 10kW heating zones.
- Adjusting heater output using PWM power control.
- Setting configurable heating time for production cycles.
- Providing a durable capacitive touch interface instead of mechanical buttons.
- Displaying power level and timer values on bright industrial displays.
- Offering manual heater testing for maintenance.
- Ensuring stable operation in high-temperature industrial environments.
Our Solution
We designed and manufactured a complete embedded control platform including:
- Custom industrial PCB design.
- Embedded firmware development.
- Capacitive touch user interface.
- PWM-based heater power regulation.
- Independent control of 4 SSR outputs driving four 10kW heating elements.
- Digital timer management.
- Real-time LED status indication.
- Heater test mode for maintenance and troubleshooting.
- Industrial-grade power electronics and protection circuitry.
- Complete assembly, testing, calibration, and production-ready manufacturing.
The final product delivers precise heat control, repeatable process performance, and a clean modern interface while eliminating the reliability issues associated with mechanical switches in industrial environments.
