The BO series is specially designed for processes in which larger sample quantities must be incinerated. Mainly used in the fields such as ashing of food, thermal cleaning of injection molding tools or determination of annealing loss.

• Tmax 600 °C for the incineration process
• Tmax 1100 °C for subsequent process
• Three-sided heating (both sides and bottom)
• Monitored exhaust air
• Only fibre materials which are not classified as carginogenic according to TGRS 905, class 1 or 2 are used
• Dual shell housing for low external temperatures and high stability

The furnace is equipped with the C550 controller with touchscreen display, featuring 10 freely adjustable programs and 20 segments and 2 extra functions. These controllers are PID microprocessor controlled with a self-diagnostic system and integrated process documentation.

The ashing furnaces have a passive safety system and integrated exhaust gas post combustion. An exhaust gas fan extracts flue gas from the furnace and simultaneously supplies fresh air to the furnace atmosphere with the result that enough oxygen is always available for the incineration process.

The incoming air is directed behind the furnace heating and preheated to ensure good temperature uniformity. Exhaust gases are led from the furnace chamber to the integrated post combustion system, where they are after burnt and catalytically cleaned. Directly after the incineration process (up to max. 600 °C) a subsequent process up to max. 1100 °C can take place.
