BCF RoTac3

The sister company Oerlikon Neumag also contributed corresponding e-save components at an exceedingly early stage. For example, the BCF tangle unit RoTac³ enables high energy savings through its targeted use of compressed air. Tangle knots are created with a pulsating rather than a continuous airflow, as is the case with conventional tangle processes. This means that compressed air is only ever used when a tangle knot is to be created. This significantly reduces the required volume flow or compressed air consumption – by up to 50 percent compared to conventional tangle units, depending on the yarn type. The component is naturally installed in Oerlikon Neumag's BCF S8 carpet yarn system, the most modern of its kind in the world. It makes a significant contribution to the energy-efficient production of carpet yarns. However, the system also convinces with impressive data thanks to the overall concept: Plant efficiency of 99%, higher throughputs of up to 15% and energy savings of up to 5% per kilogram of yarn.
