Like the bogie hearth furnace, the top hat and bottom loading furnaces will be equipped with a safety system for debinding in air to allow for a safe operation of debinding and sintering processes performed in one step. Based on the dilution principle, fresh air will be supplied to the furnace chamber in a controlled way to reliably prevent a combustible atmosphere forming inside the furnace by the exhaust gases evaporating from the charge. In addition, debinding-related functions will be monitored to protect the operator and the surrounding.

For small amounts of binder, the basic versions of the combi top hat and bottom loading furnaces are equipped with the DB100 debinding package. With this package, pre-heated fresh air is blown into the furnace so that the combi bogie hearth furnace is operated with overpressure during the debinding phase.

The DB200 debinding package is used for alternating debinding processes and/or large amounts of binder. Like the DB100 debinding package, preheated fresh air is supplied to the furnace chamber via a fresh air fan with air preheater. The furnace also has an exhaust gas fan, which removes the exhaust gases from the furnace via a separate outlet during debinding. For this purpose, the flow rates of the fresh air and exhaust gas are coordinated to ensure that there is always a slight underpressure in the furnace chamber during debinding.

  • Tmax 1280 °C
  • Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
  • Top hat furnaces (model LT): Electric or hydraulic hood drive with fixed table
    Bottom loading furnaces (model LB): driven table and fixed top hat
  • Five-sided heating from all four sides and from the table provides for a temperature uniformity up to +/− 5 °C according to DIN 17052-1 
  • Heating elements on support tubes provide for free heat radiation and long service life
  • Bottom heating protected by SiC tiles with an even stacking base
  • Multi-layer insulation consisting of lightweight refractory bricks backed by special insulation
  • Long-life ceiling design with fiber insulation
  • Automatic exhaust air flap on the furnace roof
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
  • Defined application within the constraints of the operating instructions
  • HiProSystems H1700, including Siemens PLC control system and 7" touchpanel as operating interface
