The forced convection bogie hearth furnaces W 1000/60A - W 8300/85A are used when heavy charges weighing have to be heat-treated. They are ideal for processes such as solution like glass tempering or cooling from glass, for which a good temperature uniformity is crucial. The high-performance air circulation assures that the temperature uniformity achieved throughout the work space is outstanding. A broad selection of additional equipment enables these bogie hearth furnaces to be optimally adapted to suit specific processes. 

• Tmax 600  °C or 850  °C
• Dual shell housing with rear ventilation provides for low shell temperatures for the 850  °C models
• Swing door hinged on the right side
• Heating from chrome steel heating elements for the 600  °C models
• Heating from three sides (both side walls and the trolley) for the 850  °C models
• High-performance air circulation fan with vertical circulation
• Temperature uniformity up to +/- 5 °C according to DIN 17052-1
• Bottom heating protected by SiC tiles on the bogie providing level stacking surface for the 850  °C models
• Furnace chamber fitted with inner sheets made of stainless steel 1.4301 for 600  °C models and of 1.4828 for 850  °C models
• Insulation structured with high-quality mineral wool for 600  °C models
• 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.
• Bogies with flanged wheels running on rails for easy and precise movement of heavy loads
• Electric chain-driven bogie in combination with rail operation for smooth movement of heavy loads from model W 4800
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the oven and load
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Controller B500 (5 prgrams with each 4 segments)
