Ashing Furnaces with Integrated Exhaust Gas Cleaning up to 1100 °C
The ashing furnace L ../11 BO is specially designed for processes in which larger sample quantities have to be incinerated. Fields of application are e.g. the ashing of food, thermal cleaning of injection molding tools or the determination of annealing loss. Another application is the debinding of ceramic products, e.g. after additive production.
The ashing furnaces have a passive safety system and integrated exhaust gas post combustion. An exhaust gas fan extracts flue gases from the furnace and simultaneously supplies fresh air to the furnace atmosphere with the result that sufficient oxygen is always available for the incineration process. The incoming air is guided 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 postburned and catalytically cleaned. Directly after the incineration process (up to max. 600 °C) a subsequent process up to max. 1100 °C can take place.
Standard Equipment
- Tmax 600 °C for the incineration process
- Tmax 1100 °C for the subsequent process

Muffle Furnace incl. Scale and Software for Determination of Combustion Loss
This weighing furnace with integrated precision scale and software, was designed especially for combustion loss determination in the laboratory. The determination of combustion loss is necessary, for instance, when analyzing sludges and household garbage, and is also used in a variety of other processes for the evaluation of results. The difference between the charged total mass and the combustion residue is the combustion loss. During the process, the software included records both the temperature and the weight loss.
Standard Equipment

ACCESSORIES
Chimneys
Exhaust vent
Exhaust vent for collection and upstream direction of escaping gases
Chimney with fan
Exhaust gases are better removed from the furnace and discharged. The B500 – P580 controllers can be used to switch the chimney with fan automatically (not for models L(T) 15.., L 1/12, LE 1/11, LE 2/11).*
Catalytic converter with fan
Organic components are catalytically cleaned at about 600 °C, broken into carbon dioxide and water vapour. Irritating odors are thus largely eliminated. The B500 – P580 controllers can be used to switch the catalytic converter automatically (not for models L(T) 9/14, L(T) 15.., L 1/12, LE 1/11, LE 2/11).*
* Note: If other controller types are used an adapter cable for connection to mains supply has to be ordered separately. The device will be activated by plugging in the socket.
Exhaust Air Extraction
When exhaust gases are generated during the process it is mandatory to guide them outside in an adequate way. The relevant operating instructions must be always taken into consideration. When exhaust gas pipings are installed it is always necessary that a local ventilation technician lays out the system in accordance to the real environment.
There are different possibilities to guide the exhaust gases out. In many cases the furnace is positioned under a laboratory extraction provided by the customer. In these cases the use of an exhaust vent is recommended just to guide the gases upwards.
For this purpose metal exhaust gas pipes with NW 80 to NW 120 can be used. They must be installed continuously rising and fastened to the wall or ceiling. Center the pipe over the furnace vent (for models with vent fan or catalytic converter, NW 120 is necessary. The exhaust gas pipe must not be installed with a tight fit to the furnace vent pipe since this would prevent any bypass effect. This is necessary so that not too much fresh air is sucked in by the furnace.
Chimneys
Square Saggar for Furnaces LHTC and LHT, Tmax 1600 °C
The load is placed in ceramic saggars for optimal utilization of the furnace space. Up to three saggars can be stacked on top of each other in the furnace. In models LHT 01/17 D and LHTCT 01/16 up to two saggars can be stacked. Each saggar has cut-outs for better ventilation. The top saggar should be closed with a lid made of ceramic.
Round Saggar (Ø 115 mm) for Furnaces LHT/LB, Tmax 1650 °C
These saggars are perfectly suited for furnaces LHT/LB. The load is placed in the saggars. Up to three saggars can be stacked on top of each other in order to use the overall furnace chamber.
Bottom Plates and Collecting Pans
Select between different bottom plates and collecting pans for protection of the furnace and easy loading for models L, LT, LE, LV and LVT. Steel collecting pans may deform/distort under heat. For batches that are sensitive to tipping, ceramic shelves to protect the furnace bottom are recommended.
