Avimetal’s Autoclave Module is a compact, high-capacity reactor vessel system designed for modular mineral processing plants. It includes two vertical reactor vessels housed in a double-stacked 40-foot container frame, with each vessel measuring 2,100 mm in diameter and 5,000 mm in height. The module is built for hydrometallurgical processing, leaching circuits, chemical treatment, mixing, heating, and controlled reactor applications. Its external coil heating and cooling system provides precise temperature control while preserving internal vessel capacity, enabling rapid installation, reduced foundation cost, and scalable integration into remote or modular processing plants.
