The development of turbo blower installations. According to the EU Industrial Emissions Directive, the best available technique (BAT) should be used in paper machine vacuum systems. BAT includes features such as no sealing water, automatic speed control, speed- controlled vacuum blowers, and recuperation of the exhaust air heat energy – all features of
RunEco Vacuum System with EP Turbo Blowers. About RunEco Vacuum System and EP650 AMB
RunEco presents a sustainable and environmentally responsible vacuum solution tailored for the paper industry. This system operates without water, enhancing reliability and significantly cutting CO2 emissions. RunEco's approach substitutes traditional vacuum level increases with adjustable-speed turbo blowers, alongside optimized doctoring and save-all systems. Optimal energy savings are achieved by applying vacuum precisely where necessary, facilitated by real-time, accurate water flow measurements. EcoFlow dewatering meters play a critical role in fine-tuning vacuum levels, preventing excessive energy consumption and contributing to overall system efficiency. The RunEco EP650 AMB is set to incorporate active magnetic bearing technology. It is equipped with shroudless impellers, precision-engineered from a single piece of forged unique steel alloy to ensure maximal strength and dimensional stability. The precise axial force measurement provided by magnetic bearings has enabled Runtech to refine the impeller design, enhancing process efficiency further. With the integration of active magnetic bearings, the RunEco EP Turbo Blowers boast an impressive wire-to-air efficiency exceeding 60% across a broad operating range, peaking over 70%. Active magnetic bearings offer a frictionless operation, presenting a low-maintenance alternative for customers. These bearings support the rotor magnetically, eliminating any contact between moving and stationary parts, which also negates the risk of oil leakage and is highly resistant to impeller build-up due to the completely oil-free operation.
