Runtech Systems Oy

A one stop shop to all paper machine dewatering solutions and services

Together with Nash, another Ingersoll Rand brand, Runtech Systems is the only the only company that can supply both liquid ring pumps and dry vacuum systems, or a combination of them, for a so-called hybrid system. In addition we offer doctors and save-alls, making our offering complete for paper machine dewatering. With this unique portfolio, we can always find a perfect fit for our customer’s demands, needs and budget. Producing vacuum is essential, but also a complex and cost-intensive process. The cost of energy used by a vacuum system over its lifetime exceeds its purchase price many times over. Vacuum system optimization projects provide a very efficient way to reach both cost reduction and sustainability targets.

Your reliable partner, whenever you are looking for solutions to improve the runnability and efficiency

Confidential tissue machine is a double-width tissue machine in Europe. With a target to improve energy efficiency and profitability, the existing vacuum system of five liquid ring pumps, consuming altogether ~1300 kW, was rebuilt with two EP Turbo Blowers. The turbo operation was optimized with the help of EcoFlow dewatering measurement system enabling a reduction of up to 900 kW during normal operation. All energy efficiency targets have been reached and sealing and cooling water consumption fully stopped.

Toward a smaller carbon footprint

Many companies are committed to reducing their CO2 emissions before 2030. Saving 1.5 MW in the vacuum system equals a 4,000-ton CO2 savings per year on average. Runtech looks at energy-saving projects from a wide perspective. It is not only about the vacuum pump or the Turbo Blower in the basement. Our target is to understand what happens at the machine levels and what might be wrong or causing problems on the paper machine. Understanding the dewatering process is key to a well-functioning vacuum system.

Energy-efficient and economical paper production with RunEco vacuum solution

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. High speed motors, driven by frequency converters, allow a typical RunEco blower to provide vacuum levels between 30 and 73 kPa (9” and 21” HgV). A wider 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.

Engineered solutions for pulp and paper industry worldwide

EcoFlow dewatering measurement system opens a window to the process. More than 600 paper machines have been equipped with EcoFlow.


Reliable dewatering – the basis for runnability

Each vacuum element in the machine requires a certain amount of air flow to operate at an ideal vacuum level. The needed capacity is dependent e.g. on felt life and type, paper grade, basis weight, machine speed etc.
To achieve this challenging goal we need reliable dewatering measurements.

EcoFlow dewatering measurement system is designed to measure real time water flow accurately while not sensitive to entrained air or foaming. These devices are used both under vacuum (in a separator drop leg) and in atmospheric conditions.

Dewatering and doctoring are not only related to energy consumption, but play a major role in runnability (profiles), efficiency (dirt and breaks) and profitability. Therefore, a well-designed and operated dewatering and doctoring system is one of the key issues to a well-performing and energy-efficient machine. A lot a paper machines have them but they are not effective and don’t have the adjustability that is needed to optimize them effectively.

Discover the potential of your machine

Vacuum demand varies for different paper grades, felts and machine speeds, therefore, a tailor-made solution with flexible and variable capacity can balance the supply and demand, resulting in optimized dewatering and minimized power consumption. Vacuum levels are measured at the vacuum pumps and blowers to identify problem areas. The dewatering elements such as flat boxes, save-all pans and uhle boxes are reviewed. Specialists study pressure and bleed losses to analyze the energy consumption and evaluate if the vacuum levels are too high. With the experience of thousands of audits and dewatering studies at paper mills, we are able to benchmark the effectiveness of existing vacuum systems, dewatering equipment, suction elements, fabrics and felts. Today, close to 900 Turbo Blowers have been sold globally.

This experience and expertise allows us to work with our customers, help them get the most out of their papermaking process and vacuum systems – and ensure they achieve both their operational and process goals.


With 11 EP Turbo Blowers, Progroup’s PM3 in Sandersdorf-Brehna, Germany, is the biggest RunEco installation in the world. The paper machine produces 750,000 tons of containerboard annually, 100% from recovered paper. Our other latest new machine projects in Europe include Hamburger Spremberg PM2, Palm Aalen PM5 and Mondi Ruzomberok PM19.
