Gefran 650P / 850P
Programmable PID Controllers
The Gefran 650P and 850P series deliver rock-solid process control with built-in automation power. More than PID controllers, they act like compact “mini-PLCs,” combining precision regulation with flexible sequencing, alarms, logic, and diagnostics — all in a space-saving DIN format.
The 650P gives you fast, stable single-loop PID control, ideal for ramps/soak heating applications. The 850P steps it up with dual-loop PID, enhanced logic blocks, ramps/soaks, math functions and advanced communications — perfect for complex thermal profiles, multi-stage processes, or when you need smarter control without the cost of a full PLC.
Both units feature universal inputs, crisp displays, and optional Modbus communications for seamless integration.
Gefran 650V / 850V
Motorized Valve Controllers
The Gefran 650V and 850V bring precise process control and intelligent valve management together in one compact controller. Designed for motorized valves with or without feedback, they deliver smooth, accurate positioning while regulating temperature, pressure, flow or level with rock-solid PID performance.
The 650V is the ideal solution for straightforward open/close or floating-valve applications where reliability and simplicity matter. The 850V steps up with advanced positioning, enhanced logic functions, ramps/soaks, math blocks and communication options — perfect for complex process sequences or where valve behaviour directly governs product quality and process stability.
Gefran GFXTERMO4
4-Loop Temperature Control Module
The Gefran GFXTERMO4 is a compact, displayless 4-loop temperature control module designed to plug straight into a PLC or DCS. It takes over the heating PID functions that most PLCs struggle with, delivering fast, stable and accurate control across multiple zones without complex programming.
With native fieldbus options including Profinet, Ethernet/IP and Modbus, the GFXTERMO4 drops directly into modern automation architectures. It simplifies wiring, reduces panel hardware, and centralises configuration while giving your PLC clean, high-performance temperature loops you can rely on.
Perfect for multi-zone heating systems in plastics, packaging, thermal processing and OEM machines, the GFXTERMO4 provides high-density, industrial-grade temperature control in a small, cost-effective footprint — purpose-built for connected automation.
Gefran 2500
Pressure & Tension Controller
The Gefran 2500 is a dedicated pressure and tension controller designed for extrusion, injection and winding applications. It delivers fast, stable closed-loop regulation where PLCs often struggle, ensuring precise melt pressure on plastics lines and consistent tension on winding and unwinding stations. The 2500 maintains product quality across changing loads and speeds while integrating easily into existing automation. Compact, reliable and simple to configure, it provides accurate, responsive control for pressure-critical and tension-critical processes.
Econo-controller
The Econo-Controller is a reliable, economical solution for temperature control in simpler heating or cooling applications. It provides stable PID regulation, straightforward setup, and dependable operation, available in three sizes: 48×48 mm, 48×96 mm, and 96×96 mm, making it adaptable to a variety of panel layouts and installation requirements.
