Save-All

• EP Turbo is the first variable speed and variable capacity turbo blower available • Completely water-free vacuum solution with significant heat recovery potential • Installation can be performed during a normal machine shutdown or even with the machine still running to avoid unnecessary production losses • Payback time 1-3 years • Easy to install • Economical to own and operate • Corrosion free materials • Fast maintenance EP Turbo

Double doctors

EcoFlow

RunEco concept includes: • EP Turbo blower • EcoDrop water separator • EcoFlow dewatering measurement system • Heat recovery

• High dew point closed hood • Machine hall ventilation • Optimized doctoring

Heat recovery systems normally include air-to-air or air-to-water heat exchangers. Systems are used to supply air preheating, fresh and white-water heating, machine hall heating, roof heating and hood exhaust humidity control. Optimized heat recovery improves overall heat recovery output and energy efficiency.

High dew point closed hood improves overall energy efficiency of the dryer section ventilation.

EcoFlow dewatering measurement system optimizes dewatering and vacuum levels in the forming and press sections. This results in maximized sheet dryness after the press section, improved machine runnability and maximum energy efficiency, while providing paper makers with accurate real-time feedback about the dewatering performance along the paper machine.

Case study

EcoSep

Leipa Schwedt PM4 Vacuum system rebuild in Germany reaches impressive energy saving results The mill commissioned a study of its original vacuum system. The study showed a very attractive ROI, making the investment decision easy. One of the original multistage blowers was replaced with an EP Turbo and the energy savings amounted to an impressive 900 kW. This turnkey project was carried out together with local subcontractors. Leipa Schwedt's PM4 is an 8.9-meter online coating and calendering paper machine running at 1,600m/min, located in Germany near the Polish border. Production is 300,000 tons of high-quality LWC paper.

Stora Enso Skoghall BM8 Vacuum system rebuild in Sweden fulfills its energy saving target

"In total, 7 liquid ring pumps were replaced by 1 Runtech Turbo and 2 EP blowers. Power saving in the vacuum system alone is 16.6 GWh per year. We have also achieved a significant savings in water and a reduction in maintenance costs," says Mill Supervisor Pehr Mithander.

Stora Enso Skoghall BM8 is the biggest primary fibre board machine in Europe with a width of 8.1 m and annual capacity of 450,000 tons.

EcoDrop water separators

Concrete EcoDrop water separators • 4 stage water separation • Compact design saves civil and piping costs • Eliminates the need for additional blower foundations

Case study

Lee & Man Tissue PM9, PM10, PM11 and PM12

Vacuum systems to the new tissue lines Lee & Man tissue starts up new tissue lines PM9, 10, 11 and 12. All these machines are 5.6 meter-wide tissue machines with a top speed of 2,000 m/min. Delivery included two EP Turbos and full EcoFlow system for each machine, If needed, all machines can be operated with one turbo. Machines are already running normal speeds >1900 m/min and vacuum system power consumption is at a very good level of 300 - 350 kW. For example, TM9 SEC is one of the best in the world 45 kWh/t. Just as a comparison, older L&M TM8 (-01/2017) uses liquid ring pumps and power consumption is over 650 kW.
