Heidelberg Steps Up its Environmental Commitment

It is important to differentiate between the power input and the real power consumed. “Our innovative energy recovery system in the DryStar 3000 LYYL means that we have to heat the air with maximum energy at the start of production, but can then reduce the power during long-term operation to make optimum use of the heat from the waste air,” explains Rautert. The same principle applies to various other components in the machines—it is always the maximum power required for the most critical job that is made available, but in practical applications, the use of frequency regulation and innovative control technology means that this peak power is only required in a few situations. Numerous measurements have confirmed that the Speedmaster requires much less power per sheet than other machines—and that despite its higher specifications. In future, Heidelberg will campaign for press specifications to quote the power consumption as standard.
