INVT GD600 series multi drive frequency converter helps the paper industry save energy and increase efficiency

1. Common DC bus energy feedback, achieving 30% energy savings in paper production lines
The net section, pressing section, drying section and other units of the paper production line generate a large amount of regenerative energy during operation. The common DC bus architecture of INVT GD600 series can recover and supply these regenerated energy to other power units. Compared with traditional single drive solutions, it can achieve up to 30% energy-saving effect, significantly reducing the electricity cost of paper companies.

2. Stable torque control ensures the flatness of paper production
Paper production requires extremely high stability in tension and speed, and excessive tension fluctuations can lead to paper breakage and uneven thickness. The vector control technology of INVT GD600 series can provide 0Hz/200% starting torque and stable torque output, accurately control the tension and speed of each unit of the paper machine, and ensure the flatness and quality of paper production.

3. Modular design facilitates the expansion and renovation of paper production lines
Paper companies often need to expand or renovate their production lines during their development process. The INVT GD600 series adopts a modular design, where the rectifier unit and inverter unit are independent of each other. Users can increase the number of inverter units at any time according to production needs, achieving flexible expansion of the production line. Meanwhile, standardized module design also facilitates later maintenance and replacement.
