ZRT/ZRMT vacuum annealing furnaces for aluminum foil
¡Â
Model ZRT/ZRMT is mainly applied in aluminum foil annealing, and in vacuum degassing, annealing, and tempering of metal and nonmetal material. The furnace is reliable in structure and perfect in control system. Model ZRT/ZRMT features with many good merits, such as high achievable maximum vacuum. long life span, and uniform temperature distribution.
