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.
