For many years these high-quality chamber furnaces have proven their excellent suitability
for the glass industry. These models can ideally be used for cooling, bending/slumping and glass decoration.

• Tmax 900 °C or 1300 °C
• 5-sides heating for excellent temperature uniformity
• Available for 900 °C for decorating, slumping/bending and cooling
• Heating elements on support tubes provide for free heat radiation and long service life
• Vapour vent in the middle of the roof (excellent ventilation)
• Smoothly adjustable and easy-to-operate air inlet flap or sliding damper
• Self-supporting arch provides for high stability
• Models N 200..GS - N 500..S with special measurements for cooling
• Double-walled, non-warping door with fibre seal (from model N 440..) or brick on brick for models N 100.. to N 300..
• Special door lock for easy handling
• Multi-layer insulation consisting of lightweight refractory bricks and backed by special fibre insulation
• Models up to N 300/.. are supplied with a removable stａnd
• Floor heating elements protected by SiC tiles to provide for level stacking floor
• Description of the control system see page 42

Additional equipment

• Electrically driven exhaust air damper activated via the extra function of the controller
• Fan system for faster cooling with manual or automatic control
• Fiber-insulation for shorter cycle times, especially cooling periods
• Multi-zone control for optimal temperature uniformity in the useful chamber
• Also available for 1400 °C
• Furnace in HDB design featuring fresh air pre-heating, exhaust gas ventilation and an extensive
• safety package for debinding and sintering in one process, i. e. without transfering
• the material from the debinding furnace to the sintering furnace.
