HEIDELBERG LAUNCHES NEW GENERATION COMBISTAR PRO

1391

Heidelberg has launched the Combistar Pro, which combines dampening solution conditioning with inking unit temperature control. It also incorporates free-cooling technology for further energy savings.

The press uses energy efficiently, preventing waste, and uses eco-friendly (raw) materials which have a big impact when it comes to sustainable print production.

Heidelberg is systematically working on solutions that, in addition to reducing waste—the primary factor in improving sustainability—also boost energy efficiency. This combination unit conditions the dampening solution and ensures constant inking unit temperature control. It is now equipped with more energy-efficient pumps and electronically controlled compressors that cut energy costs by up to 50 per cent.

In the new Combistar, the inking unit pump for temperature control circulation is fitted with an electronically controlled drive and the refrigerating units now have an energy-efficient digital scroll compressor.

Step-less adjustment of the refrigerating units to the cooling capacity required by the machine significantly boosts the system’s efficiency. Units such as the Combistar are the third-highest consumer of electricity in a press after the main motor and the air supply system. In the case of presses with dryers, they occupy fourth place.

Heiko Mazur, owner and managing director of Häuser KG, and his print shop manager Rafael Langer have achieved energy savings of 34 per cent with the new-generation Combistar. The field test of the new energy-efficient Combistar generation at Häuser KG went extremely well.

‘The energy-efficient Combistar used 34 per cent less power than the older Combistar unit,’ said Heiko Mazur, owner and managing director of Häuser KG. ‘Calculated over an entire year, this adds up to energy savings of 15 000 kWh. Based on the total electricity consumption of all the presses, which amounted to 250 000 kWh, this represents a saving of no less than six per cent,’ he added.
