Renova offers a wide range of integrated systems for web tension regulation in open-loop tension or closed-loop systems which stand out for their maximum accuracy, linearity, user-friendliness, precision and flexibility.


On unwinders, Renova control systems are ideal with the company’s pneumatic brakes or magnetic powder brakes whilst Sensorex loads cells, the Reset amplifier, Isomatic control panel, and the Ep converter transducer keep the desired web tension constant, avoiding the possibility of material breaks in any phase of web processing.
