PETKUS SC Calibration — flexible, gentle sizing for every seed

SC calibrators sort seed precisely by size and shape while protecting vitality. Configurable decks with up to 10 screen levels deliver sharp separations, achieving up to 5 calibres in a single pass. Sizing can target grain width or thickness, and a wide range of interchangeable screen segments lets you tailor the machine to each crop and lot. A standard vibration feeder ensures uniform, gentle product distribution; a unique tensioning system lets screens roll out on casters for screen changes up to 70% faster. Optional cameras and sensors provide live process visibility on the HMI or remotely, and the ALR electrical screen-tensioning system adds automatic monitoring for safer, error-free changeovers.
