Introducing the RunEco EP650 AMB Turbo Blower

In response to market needs, Runtech Systems is launching a new turbo blower model for paper machine vacuum systems. The new RunEco EP650 AMB Turbo Blower features active magnetic bearings. The design of EP Turbo Blowers is characterized by its streamlined efficiency, featuring impellers mounted directly onto the motor shaft. This design choice not only simplifies the system but also enhances its reliability, as it requires just two bearings throughout the entire blower.

Moreover, the compact design expedites the installation process, making it a swift and straightforward task. With active magnetic bearing technology, these turbo blowers not only boast increased energy efficiency but also demand less maintenance, further enhancing their appeal and reducing long-term operational costs.

Ville Lahdensuo, R&D Director at Runtech Systems, asserts,

“We have been investigating alternative bearing technologies to expand our range of offerings. Runtech has already implemented active magnetic bearings, in the RunEco EP1000 at a paper mill. Active magnetic bearing technology is a significant advancement toward more sustainable papermaking, offering remarkably low total cost of ownership. The compact size and material efficiency of EP Turbo Blower technology, coupled with reduced energy consumption throughout its lifespan, make it an unparalleled solution.”

“Runtech consistently enhances its product line to deliver efficiency, customer satisfaction, and ecological benefits. EP Series Turbo Blowers have been pivotal in driving energy efficiency in paper mills for two decades. Today, we have sold over 1,100 Turbo Blowers globally. Given the average energy saving of 45%, this translates to energy savings of 2.6 TWh and a reduction of 781,000 tons of CO₂ a year. We actively collaborate with our customers to deepen the understanding of their operational needs, driving both efficiency and cost-effectiveness. A milestone was achieved in September when the Kotka factory celebrated the production of the 1000th EP Turbo Blower. With our continuous focus on R&D, we aim to ensure that we consistently provide our customers with advanced, energy-efficient, and adjustable vacuum technology,” says Hannu Kääriä, Sales Director, Runtech Systems.

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.

EP650 AMB on the show floor at SPaper and Tissue World

The new turbo blower model will be showcased at two industry events this spring. Runtech, along with its representative Ferpal, will exhibit at SPaper in Zaragoza, Spain, from March 4-6.

Tissue World Düsseldorf, the largest tissue event in Europe, will take place from April 8-10, 2025. Runtech Systems will be exhibiting at stand H32.
