Energy Efficiency in Paper Machinery: Cutting Power and Heat Use Across Converting Lines

Paper converting machinery consumes significant energy in drives, drying, and heat. Efficiency comes from variable-speed drives that match power to load, heat recovery that reuses drying energy, and optimized machine settings that avoid idle waste. Together these cut energy cost per unit — often by double digits.

The Scenario: Waste hides in drives and heat

Energy efficiency faces three challenges:

Pain Points

• Fixed-speed drives waste power when the line runs below full load;
• Drying and heat lose energy to the surroundings that could be recovered;
• Idle time and poor settings consume energy without producing output.

The Solution: Three energy solutions

Three practices cut energy use:

1. Variable-speed drives VSDs match motor power to actual load, cutting waste at part load.

2. Heat recovery Reusing drying and process heat cuts the energy lost to the surroundings.

3. Optimized settings and idle control Tuned settings and idle shutoff eliminate energy burned without output.

The Result: Lower cost per unit

With these measures, energy cost per unit falls, often by double digits. This improves margin and sustainability in one move.
