‐ pit furnaces with usable diameter 1.200 x 3.000mm with atmospheres for heat treatment or for annealing and load up to 3.000kg;
‐ horizontal movable muffles furnaces with dimensions up to diameter 1.600 x 3.000mm with vacuum and nitrogen or formengas controlled atmospheres and load up to 2.000kg;
The choice of the furnace depends on the needed hourly production and on the weight‐volume ratio of the parts to be treated.
