Runtech Systems has been selected as the vacuum system supplier for Zhejiang Jinli Environmental Protection Paper Industry’s two new board machines, PM10 and PM11 in Quzhou City, Zhejiang, Province, China. The delivery includes two RunEco vacuum systems. Both systems comprise of five EP Turbo Blowers and parts for concrete water separators.
With these RunEco systems, the mill will be able to produce needed vacuum in an energy-efficient, water-free way. PM10 will produce gray board paper with a machine width of 5,660 mm. PM11, with a width of 5,600 mm will produce kraft liner and gray board. Both machines are supplied by China local paper machine supplier. PM10 already started in April 2023, and startup for PM11 is scheduled for July 2023.
“Runtech turbo systems show great stability and energy saving in PM9 which started 2 years ago. At the same time, Runtech showed great project handling ability and service,” says Mr. Li Caipeng, Chief Engineer, Zhejiang Jinli Environmental Protection Paper.
“During the project phase customer compared all vacuum systems available on the market today. For their new board machines they decided to go with the most complete and most CO2 saving solution,” says Wen Le, Site Leader, Runtech Systems.
RunEco EP Turbo Blowers are designed to operate efficiently across a wide range of vacuum levels and air flows. It allows paper mills to optimize vacuum levels whilst taking advantage of the high efficiency. High speed motors, driven by frequency converters, allow a typical EP Turbo Blower to provide paper machine vacuum levels between 30 and 70 kPa. A wide range of impeller designs allows highly efficient levels across the operating range. This means that the amount and the usage of throttling valves can be reduced to a minimum. The result is energy savings of 30 to 70% when compared to traditional vacuum systems.
