The fast-firing decorating furnaces with infrared heating are especially suitable for decal firing of glass or ceramics at working temperatures up to 900 °C. The fast-firing decorating furnace is equipped with two manually movable tables on castors for easy handling. Both tables and the furnace chamber are insulated with non-classified fiber materials. With the fiber insulation in combination with the infrared heating, which provides for a fast surface heating, the furnace achieves particularly short process cycles. Depending on the charge type the tables may be charged in several layers what allows for an optimal use of the available space. The charge surface with applied decal should face towards the heating elements which are positioned in the roof. While one charged table is positioned in the fast-firing decorating furnace the other table can already be charged outside the furnace. If the charge permits, the table with still warm charge can be driven out of the furnace and the other table is pushed into the furnace to use the residual energy. To vent the exhaust gases generated during decor firing, the furnace is equipped with a motor-driven exhaust gas flap which can be activated via the controls. The stainless steel exhaust hood which is positioned above the motor-driven flap will be connected to customer’s ductwork.

  • Infrared heating elements in the roof with reflectors installed on each table
  • Insulation made of non-classified fiber materials provides for fast process cycles
  • Process times of hardly three hours from cold to cold possible, depending on the charge and the working temperature
  • Alternating table system on castors, very easy to move
  • Motorized exhaust-gas flap on top of the furnace with stainless steel exhaust hood
  • Easy-to-operate controls
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
