GEFRAN offers a wide range of components for automating primary processes in the wood industry, as well as complete solutions, from sensor to actuator, for work processes and coupling of materials, surface finishing, painting, and storage:
- displacement, force, pressure transducers for precise positioning of mechanisms (size settings, cutting, etc.) and machine parameter control systems.
- sensors, controllers, programmers and actuators for all processes with heating phases (spreading, gluing, drying, bending, edging, etc.), and for programmed control of ambient parameters (humidity and temperature) in seasoning systems.
- positioners and level indicators for sanders.
- configurable indicators to display (on the machine or control panel) other parameters such as input/rpm’s, pieces produced, etc.
Choosing GEFRAN means giving added value to your system in terms of production flexibility, precision and repeatability, guaranteed by components that can sustain a high number of cycles under harsh conditions.

GEFRAN offers a wide range of sensors, indicators and controllers for the chemical pharmaceutical industry, suitable for processes that demand reliability, precision, diagnostics and data transmission to supervisory units.
There are many complete solutions for temperature control, with configurable acquisition inputs and outputs for electric heaters, fans, inverters, proportional or servo-controlled valves. Parameter recipes can be managed digital communication with PLCs and other control units. Heat profiles can also be run.
The wide range of products also includes controllers and programmers with advanced functions such as cascade and ratio controls.
The components are also ideal for plant expansion and maintenance, thanks to their great versatility in terms of possible installations, materials used for sensing elements, measurement ranges, resolution and sampling speed, types of output signals, digital communication and protocols.
