Runtech Systems delivered a web stabilization improvement project to Visy. The delivery to Gibson Island PM8 included RunPro Web Stabilizers for single- and double-felted drying sections and EVst pocket ventilators. Stabilizer high-release nozzles are fed with RunPro Turbo Compressors to create effective vacuum levels on sheet release point of top dryers. In addition, tail threading was updated into ropeless after drying section with RunShooter technology.
“We would like to extend our sincere thanks to Visy Industries and everyone involved. From the early planning phase to commissioning, this has been a great example of what can be achieved through open communication, shared expertise and commitment on both sides. The close collaboration on-site enabled smooth execution and supported achieving the shared targets. The outcome is a combination of smart technology and strong teamwork: excellent runnability in both single- and double-felted drying sections, reduced draw from the press to the dryer section, and a more even paper moisture profile supported by improved pocket ventilation. Additionally, the new ropeless tail threading setup brings added safety and reliability to tail feeding in the after drying section,” says Hannu Kääriä, Sales Director, Runtech Systems.
EVsf3-V high release stabilizers together with traditional blowing nozzle stabilizers operate without any mechanical contact with fabrics, giving easily adjustable vacuum levels and extra low maintenance costs. High release stabilizers together with vacuum rolls keep sheet in perfect contact with fabric in whole slalom area and that way provide a possibility to reduce draw between press and dryer sections without losing runnability.
EVdf stabilizers improve double tier area runnability, providing better pocket ventilation at the same time. Improved pocket ventilation with proper air settings gives flat pocket humidity. The overall results are less sheet breaks, more efficient sheet drying and even moisture profiles, resulting in major expected improvements preventing wrinkles and negative paper properties due to an uneven drying process.
Runtech Systems replaces traditional lubricated compressors with high-efficiency turbo compressors as the standard. The RunPro Turbo Compressor supplies compressed air at 0.3 – 0.6 bar. Its integrated variable speed drive ensures precise process control by directly adjusting the high-speed motor.
