F4T™ Temperature and Process Controller
As food and beverage manufacturers modernise thermal processing operations and move toward greater automation and electrification, flexible process control has become essential for maintaining product quality, improving efficiency, and simplifying compliance. The Watlow® F4TTM process controller combines advanced temperature and process control with an intuitive touchscreen interface, helping manufacturers manage complex thermal applications with greater precision and ease.
Designed for demanding industrial environments, the F4T integrates PID temperature control, data logging, trend charts, over/under-temperature limits, timers, counters, alarms, and recipe/profile management into a single scalable platform. Its modular I/O architecture allows configurations from 1 to 36 I/O points, making it suitable for applications ranging from ovens, dryers, fryers, and boilers to environmental chambers, packaging systems, and electrically heated process equipment.
The 4.3in colour touchscreen interface simplifies setup and operation while reducing engineering time and operator training requirements. Features such as ramp-and-soak profiling, adaptive TRU-TUNE®+ control, cascade control, and multi-loop capability help improve temperature stability, reduce overshoot, and maintain process consistency across multiple heating zones.
For food and beverage manufacturers requiring traceability and process documentation, the F4T supports data logging, batch processing, encrypted data file options, and integration with plant-wide automation systems. Multiple communications protocols, including EtherNet/IP™ and Modbus® TCP, support digitalisation and Industry 4.0-ready architectures.
Combined with Watlow heaters and Eurotherm power control technologies, the F4T provides a flexible platform for electrically heated food and beverage processes focused on efficiency, repeatability, sustainability, and reduced engineering complexity.
