High temperature ashing furnace range is designed specifically to provide optimum ashing conditions to ensure complete combustion of the sample. For those laboratories where ashing is interspersed with other heat treatment work the ashing furnace provide all of the advantages of the HT design, but with a higher maximum operating temperature of 1100 °C with Integrated Exhaust Gas Cleaning.
HT ashing furnace 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
Three-side heating (both sides and bottom)
Ceramic heating plates with embedded heating wire
Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
Exclusive use of insulation materials without categorization according to EC Regulation.
Steel collecting pan protects the bottom insulation
Spring-assisted closing of the ashing furnace door (flap door) with mechanical locking against unintentional opening
Thermal/catalytic post combustion, integrated in the exhaust channel, up to 600 °C in function
Temperature control of post combustion can be set up to 850 °C
Monitored exhaust air
Inlet-air preheated through the bottom heating plate
Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load.
Two tier rack system doubling the sample capacity
With sample trays and loading handle allows for large number of samples
Ideal for ashing foods, plastics, coal & other hydrocarbon materials
Preheating of air before it enters the chamber
Protection of the elements from carbon build-up or corrosive atmosphere, using silicon carbide tiles.
