Reifenhäuser Kiefel Extrusion says that several thousand euros can be saved every year in blown film production through simple measures such as the enclosure of certain line components.
The amount of savings depends on the component chosen. Tests conducted in the Technology Center of Reifenhäuser Kiefel Extrusion with various raw materials and different production parameters have shown the enclosure of barrels and heater-bands to be the most efficient measure.
The company's engineers were able to save extruder heat energy between 20 and 50% alone by providing the barrels and heater-bands with insulating sleeves. This means that energy savings of up to 100,000 kWh/year can be obtained when encased barrels instead of non-insulated ones are used in a 5-layer blown film line processing resin of 500 kg/hour.
According to Reifenhäuser Kiefel, these savings correspond to about €12,000, depending on the energy costs.
"Energy costs are no longer a negligible factor in the production of extruded plastic products", says Ralf Pampus, responsible for the subject of energy efficiency within the Reifenhäuser Group. "Within the framework of our Blue Extrusion initiative we are developing concrete measures that can easily be put into practice to provide significant savings for our customers."
