Reduce electricity consumption

• Vacuum sources such as fans, pumps or blowers are major consumers of electrical energy.
• Vacuum is very often not on the radar of paper manufacturers - "it's just there".
• Vacuum and friction are the drivers that influence the amount of drive power required.

With our know-how, products and solutions, we can help you to reduce electricity consumption as follows - and all while maintaining or even improving product quality:

• Optimization of vacuum demand and adaptation to production requirements.
  • Optimization of the vacuum curve over the entire wire section.
  • Use of automatic valves for reproducibility.
  • Re-engineering of the pipelines.
  • Reduction of vacuum consumers and therefore vacuum sources.
• Reduction of needed drive power, e.g. through
  • Replacement of outdated dewatering systems with modern technology.
  • Optimization of dewatering foils and covers with regard to current production conditions (design, material, servicing).

All projects presented…

• ... show that it is possible to save resources while reducing production cost.
• ... achieved consistent or even improved product quality.
• ... have a return on investment of a few months only taking into account the overall added value achieved.
• ... have been implemented many times - no prototypes or trial installations.

TARGETS ACHIEVED

• Reduced power consumption for vacuum supply due to lower vacuum heights.
• This eliminates the need for a 250 kW vacuum pump including necessary maintenance, spare parts, etc..
• Same or even improved product quality.
• Return on investment within a few months.

TARGETS ACHIEVED

• Elimination of 180 kW vacuum supply for wire cleaning suction system.
• This results in electricity savings of 1.44 GWh per year.
• Same or even improved product quality.
• Return on investment within a few months.

TARGETS ACHIEVED

• Optimization of dewatering elements (boxes, foils, covers).
• Optimization of vacuum curve over entire wire section.
• Increased dewatering performance by 7%.
• Reduction of total vacuum requirement by 12%.
• Reduction in drive power by 8%.
• Same or even improved product quality.
• Return on investment within a few months.
