Ripe for the Energy Oscar

Hollywood may be the home of the superstars, but all eyes are on the Oscar-worthy candidates from Heidelberg: the new peripherals AirStar 3000, DryStar 3000 and CombiStar 3000. These performers ensure optimum printing conditions and increase production speed - and in so doing use significantly less energy to achieve greater performance.

Humphrey Bogart has one. So does Charlie Chaplin. And of course Marylin Monroe. The biggest stars are immortalized with exactly that - a star - on the Walk of Fame in Hollywood. No Heidelberg Star has yet been given this honor - although the peripherals play equally convincing roles in many print shops. All together, Heidelberg offers 13 stars in different categories, which up until now were the following: AirStar for the air supply, CoatingStar for the coating supply, CombiStar for the inking system temperature control, CutStar as a role CutStar roll sheeter, DryStar and DryStar UV for drying, FoilStar for cold foil finishing, HydroStar for preparation of the dampening additive, InkLine for the ink feed, PowderStar for the powder application, CleanStar for the powder extraction, StaticStar for the electrostatic discharge of the sheets, ScrollStar for printing air supply and WashStar for disposing of cleaning agents.

The 3000 series became available several months ago. It includes the air supply cabinet AirStar 3000, the dryer DryStar 3000, the combination machine for temperature control in the inking system and dampening solution supply and the CombiStar 3000. The new Star generation is even more powerful than its predecessor and reduces production costs at the same time since it uses significantly less electricity and also helps to save resources like oil, alcohol and dampening solution. This of course also preserves the environment - a further plus.

Often the sequels of successful Hollywood movies don't live up to expectations, but it's a whole different story with the AirStar 3000, the successor to the most widely used air supply cabinet on the market, with its 15,000 installations. The AirStar 3000 uses up to 50 percent less electricity than comparable air supply cabinets - and that at higher performance. A newly developed turbo radial blower, which has a rotor that runs with speeds of up to 15,000 rpm, makes this possible. This high rotation speed is achieved through the use of new manufacturing techniques.

The AirStar 3000 is equipped with one to five such turbo radial blowers. The highlight of this system: The second or further blowers turn on automatically only when the machine needs a corresponding amount of suction and blast air. This is the case with very high grammages or a high printing speed, for example. "Since blowers are regulated according to need, a print shop with a Speedmaster XL 105-6+LX operating in three shifts saves around 82,500 kilowatt hours of electricity yearly," calculates Bernd Thuerauf, from product management for peripherals at Heidelberg.

A further plus point: The blowers are very resistant to wear and tear and rarely need maintenance. The AirStar 3000, which is housed in a separate cabinet, is substantially smaller than other solutions and thereby creates space in the pressroom. The cabinet's sound insulation also reduces the noise level. Furthermore, the accumulated air is safely filtered and the heat well-dissipated. This contributes to a pleasant atmosphere in the pressroom. Even operation is comfortable: For each job, the printers can save the air settings so that they can recover the configuration with just one press of a button in the Prinect CP2000 Center for recurring jobs.
