About RunEco vacuum system

RunEco vacuum system is developed specially to take into account the challenges and demands related to the dewatering and runnability of paper machines. EP Turbo Blowers are designed to operate efficiently across a wide range of vacuum levels and air flows allowing paper mills to optimize vacuum levels. High speed motors, driven by frequency converters, allow a typical EP Turbo Blower to provide vacuum levels between 30 and 70 kPa. A wide range of impeller designs allows highly efficient levels across the operating range.

The EP Turbo Blower’s water-free design not only reduces water and chemical consumption within the vacuum system but also eliminates the need for water-related equipment like cooling towers and circulating pumps. Nip dewatering, combined with doctoring, significantly improves energy efficiency and machine performance. A well-designed and operated dewatering and doctoring system is crucial for both energy consumption and paper quality. Runtech’s EcoFlow, save-alls, and double doctors offer a tailored approach to meet these needs.
