These compact tube furnaces with SiC rod heating and integrated switchgear with controller can be used universally for many processes. They represent an inexpensive variant in the high-temperature range. The standard mounting options for accessories make them flexible in use for a wide range of applications. The SiC heating elements arranged parallel to the working tube provide for an excellent temperature uniformity.

Standard Equipment

• Tmax 1600 °C
• Working temperature 1500 °C, increased wear and tear must be expected in case of working at higher temperatures
• Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
• Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
• Active cooling of housing for low surface temperatures
• Ceramic working tube C 799 including two fiber plugs for operation under air
• Type S thermocouple
• Solid state relays provide for lownoise operation
• SiC heating elemens, easy to replace
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Controller P580 (5 programs with each 4 segments)

Additional Equipment

• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Charge control with temperature measurement in the working tube
• Three-zoned design (heated length from 500 mm) for optimization of temperature uniformity
• Gas supply systems 1, 15, 2 or 4
• Process control and documentation via VCD software package for monitoring, documentation and control
