Exhaust air and wastewater heat recovery starts with simple reduction of the radiated heat by means of innovative isolation and continues through to high-efficiency systems for exhaust air heat recovery on cylinder dryers. Benninger uses individually optimised heat exchangers in the wastewater heat recovery systems that are already in widespread use, depending on the application process and waste water volume. Lye recovery, which Benninger recently included in its portfolio, offers considerable advantages during mercerisation. The weak lye is concentrated by evaporating the water and is then available for reuse in the mercerisation process. This enables customers to benefit from both inexpensive and environmentally friendly production. Another area of focus in the field of finishing is always minimum use of chemicals. Intelligent application systems such as the IMPACTA modules guarantee the precise application of chemicals for the respective process without having to draining off the excess liquor. A particularly resource-saving process in this respect is the CPB reactive dying process. After the take-over of KÜSTERS in 2007, Benninger was able to successfully combine the Küsters and the Benninger technologies, especially in the padder, bleaching and dyeing steamer fields. Benninger will reveal the comprehensive advantages of the Original Benninger-Küsters DyePad as well as the other innovations in the field of wet finishing at ITMA.
