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
- 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 No. 1272/2008 (CLP)
- Steel collecting pan protects the bottom insulation
- Spring-assisted closing of the 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 oven and load
- Controller C450 (10 programs with each 20 segments)
- Defined application within the constraints of the operating instructions
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
Process Control and Documentation
As one of the world’s largest furnace manufacturers, Nabertherm has many years of experience in the design and manufacture of standardized and customer-specific control systems. All controls are characterized by a very high level of operating convenience and even the basic version has extensive basic functions. Depending on the requirements, the functions can be expanded and adapted to your needs. Professional software solutions for single or multiple furnace management as well as process and batch documentation based on our Nabertherm controllers complete the range.
Also for compliance with industry-specific standards that define process control and documentation, such as for example, the AMS 2750 F for aviation, the CQI-9 in the automotive industry or the FDA in the pharmaceutical industry we offer standardized solutions.
Additional Equipment
- Process control and documentation via VCD software package for monitoring, documentation and control
