Making maximum use of energy
Minimising the energy consumption of the individual units is only one aspect of the Grafix energy concept in peripherals technology – albeit an important one. Another aspect lies in the recycling of waste heat energy generated by cooling and suction processes and in avoiding secondary energy consumption.
Recycling of energy to the peripheral systems
- The PHU (preheating unit) links two simultaneously operating peripheral systems by using waste heat from the dampening solution and inking unit temperature control for preheating the hot air for drying. The PHU can be retrofitted at any time.
- The hot air recycling system uses the hot air discharged during the drying process to directly preheat additional hot air to be generated. The mechanical swivel system required for this must be taken into consideration when configuring the printing machine.
Recycling of energy to building services
Wherever the interfaces of the heat discharge from the printing machine with the building services are located, a high energy yield potential is provided, particularly in the case of UV drying. Grafix is working continuously to provide solutions for this on a situational basis – in principle water-bound heat re-use systems are given preference because in this case the installation cost and pipe leakage are at their lowest.
Avoidance of secondary energy consumption
Grafix always considers recooling concepts in the context of building services and systems engineering. For instance, an external cooler makes use of the low ambient temperature, thereby minimising its influence on domestic climate control.
However, relieving the load of existing systems, such as when connecting small UV dryers to an existing dampening solution and inking unit cooling system, not only minimises the installation costs but also optimises the efficiency of a system.
