Piece szybowe z cyrkulacją powietrza ogrzewane elektrycznie lub gazowo

Due to their robust design, these pit-type furnaces with air circulation are particularly useful for a professional heat treatment demanding optimum temperature uniformity. Production processes such as tempering, solution annealing, artificial ageing, and soft annealing can be realized with these pit-type furnaces. 

• Tmax 600 °C or 850 °C
• Useful for heavy charge weights
• Powerful air circulation fan in the furnace lid for vertical air-circulation in the furnace chamber
• Heating chamber with air baffle cylinder, feeding the recirculated air through the bottom grid
• Pneumatic or hydraulic lifting device for swing lid
• Temperature uniformity up to +/−  3 °C according to DIN 17052-1
• 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
• Controller with touch operation C540 (10 programs with each 20 segments)
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Freeware NTEdit for convenient program input via Excel^TM for Windows^TM on the PC
• Freeware NTGraph for evaluation and documentation of firings using Excel^TM for Windows^TM on the PC
• MyNabertherm App for online monitoring of the firing on mobile devices for free download
