Based on the standard furnaces N 30/65 HA et. al., these furnace models with air circulation are equipped with a specially sealed housing and protective gas inlet and outlet. The furnaces can be used for inert gas heat treatment allowing tempering, annealing under protective gas, and curing. You can use them also for heat-treating magnesium under certain conditions. While these furnaces are not appropriate for furnaces that require a high-purity atmosphere, they offer a compelling value for more forgiving processes.
