These high-quality chamber furnaces for firing, sintering and tempering have qualified themselves with the reliability for many years in daily use. Thanks to their five-side heating, the furnaces provide for a very good temperature uniformity. A wide range of additional equipment perfectly adapt these models to the process requirements.

• Tmax 1300 °C, 1340 °C or 1400 °C
• Five-side heating provide for good temperature uniformity
• 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 and long-life ceiling construction, with bricks laid in arched construction
• 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/.. with removable stand
• Bottom heating elements protected by SiC tiles for level stacking surface
• Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

Additional equipment

• Motor-driven exhaust gas flap
• Fan system for faster cooling with manual or automatic control
• Protective gas connection as well as sealing of the furnace housing for purging the furnace with protective gases
• Manual or automatic gas supply systems
• Fiber-insulation for shorter cycle times, especially cooling periods
• Multi-zone control for optimal temperature uniformity in the useful chamber
