Gypsum plasterboard plays a key role in modern interior design, offering versatility and high performance when raw material properties and end-product characteristics are precisely aligned. Grenzebach draws on decades of expertise to deliver tailored production lines that provides premium quality gypsum. A standout innovation is the Ultra High-Efficiency Dryer (UHE Dryer). Compared to the best available dryers, it saves up to 33% in energy through a sophisticated combination of high- and low-temperature sections, including a transition zone. The low-temperature section utilizes 100% waste heat, reaching values of up to 400 kcal/kg. In addition, the dryer recovers between 45% and 50% of water, and is compatible with renewable energy sources and low-calorific heat — an industry first. This efficiency enables significant cost savings, and supports sustainable production processes.
