Dryer
In addition, the warm air is now generated in the dryer cassette directly above the sheet and is no longer supplied via piping, which resulted in losses.
Last but not least, the warm air is applied via patented round nozzles with excellent efficiency and energy-saving credentials.
Incidentally, a Speedmaster generates around 125 kW of waste heat in total – energy that can be used for other purposes.
To further improve energy efficiency in the pressroom, you should therefore integrate water- cooled units such as AirStar and CombiStar into the overall energy infrastructure.

Overall, CombiStar Pro reduces energy consumption by 400 kWh per million sheets.
That saves you 8000 euros per year (based on a print volume of 40 million sheets and electricity costs of about 50 cents per kWh).

When drying printed sheets with DryStar Combination, you can set new standards in energy efficiency.
Our new development features a minimal distance of just 80 millimeters to the sheet.
The completely redesigned gripper bar now guides the sheet directly under the dryer. The bar was optimized using a wind tunnel to minimize the design height.

Compressed air
According to the calculations of the Fraunhofer ISI, it costs up to three cents to produce one cubic meter of compressed air.
That makes it worth your while to regularly check and adjust both the volume actually required and the necessary working pressure.
Compressed air
Experience shows that up to 30 percent of the compressed air generated is lost due to leaks. According to the Fraunhofer ISI, even leaks with a diameter of just three millimeters cost around 2800 euros per year (8000 hours of operation, 6 bar, 0.10 euros/kWh).
A leak check should therefore be part of your team’s standard routine.
The main drive of Speedmaster presses is a frequency-controlled sine synchronous motor.
As a result, you benefit from an energy efficiency of up to 95 percent – around 5 percent higher than other drives.
What’s more, bidirectional inverter operation means other consumers in the press can harness the energy that is released when the brakes are applied to the motors.
Drive
Thanks to the AirStar and CombiStar water-cooled peripheral units, you can remove waste heat from the press far more efficiently than with air cooling.
The pressroom heats up less and the production environment is stabilized.
Water cooling is also a far less energy-intensive solution than air-conditioning and ventilation systems.
The AirStar Pro air supply cabinet is equipped with several frequency-controlled turbo radial blowers that are activated automatically according to the air consumption.
With this innovative technology, you benefit from an efficiency level of up to 70 percent.
By comparison, standard air generators achieve an efficiency rating of just 35 percent.

With the innovative “free cooling” system on CombiStar Pro, external air cools the inking unit when the outdoor temperature is up to around 20 degrees.
Only at higher temperatures do the cooling units lend a helping hand. Their stepless adjustment to the cooling requirements of the press cuts energy consumption by up to 15 percent.
