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

  • Like muffle furnaces L(T), except:
  • Delivery includes base, ceramic plunger with base plate in the furnace lining, precision scale and software package
  • 4 scales available for different maximum weights and scaling ranges
  • Process control and documentation for temperature and combustion loss via VCD software package for monitoring, documentation and control
  • Controller B510 (5 programs with each 4 segments)

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 furnace and load
  • Controller C550 (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

These muffle furnaces are a good alternative to the familiar L(T) ../12 series when higher application temperatures are needed.

Standard Equipment

  • Tmax 1400 °C
  • Heating from two sides
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • 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)
  • Adjustable air inlet integrated in door
  • Exhaust air outlet in rear wall of furnace
  • Controller B510 (5 programs with each 4 segments)
  • Solid state relays provide for lownoise operation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
