The HB top hat furnaces are available with usable volumes of 80 to 560 litres. The hood moves up and down automated giving access to the hearth for loading and unloading. Alternatively the HB-BL 240 and HB-BL 430 litres model the hood is steady and the hearth moves up and down in a bottom loading way.
For debinding of technical ceramics, preheated air fans can be installed blowing hot air through the hearth into the furnace chamber. For safe combustion of binder gases several options are available, e.g. active propane gas after burner or catalytic oxidiser.
