German machinery producer Bruckner has developed a new stenter concept with double heating system. The concept enables the company to operate production lines with not just gas or oil but also other combinations with steam or renewable energies are possible. In addition, Bruckner has developed intelligent assistance systems for its machines that allow the machine operator to use the best possible process to operate the line as energy-efficiently as possible. It also saves energy with its energy-efficient motors or heat-recovery and exhaust air cleaning systems.

To reduce chemical usage, Bruckner has developed Eco-Coat Minimum Application Unit for knitted, woven fabrics and also nonwoven fabrics. With the minimum application via an engraved roller, a single-sided application of up to 100 g/sq m can be achieved. The unit enables double-sided and higher application quantity, by impregnation in the nip. Irrespective of the selected fabric path, a very small liquor reservoir means that only minimal quantities of waste water are produced when changing batches or liquors, and the use of chemicals can also be significantly reduced. In addition, less water has to be evaporated in the subsequent drying process than, for example, in the case of impregnation in a water bath, so the energy requirement is significantly reduced.
