These forced convection chamber furnaces provide good temperature uniformity. Due to their compact benchtop design, this series is very well suited for use in laboratories or areas with limited space.
- Choice of models with Tmax 650 or 850 °C
- Horizontal air circulation with optimum distribution via stainless steel baffles
- Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
- Integrated control unit
- Swing door is hinged on the right side, door opening temperatures up to 400 °C
- Optimum air distribution enabled by high flow speeds
- Air inlet on rear wall of the furnace
- Adjustable exhaust port in the furnace ceiling (not model NAT 15/65)
- Access port (15 mm Ø) in the furnace ceiling (not model NAT 15/65)
- Temperature uniformity up to ±6 °C according to DIN 17052-1 (±5 °C for NAT 15/65 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 fibre' (RCF), which is classified and possibly carcinogenic, is not used. Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load (not model NAT 15/65).
Applications include preheating of components for shrink-fit processes, heat treatment of metals in air such as aging, stress relieving, soft annealing or tempering, and heat treatment of glass.
Approximate heat-up time to Tmax (in an empty furnace) is 40 minutes for NAT 15/65 models, 80 minutes for NAT 30/65 models, 100 minutes for NAT 60/65 models, 190 minutes for NAT 15/85 models and 230 minutes for NAT 30/85 and NAT 50/85 models.
Units feature different controllers: the standard touch operated B500/B510 controller with touch screen display, featuring five freely adjustable programs, four segments and two extra functions. Alternatively chose the C540/C550 controller with touch screen display, featuring 10 freely adjustable programs and 20 segments and two extra functions. All these controllers are PID microprocessor controlled with a self-diagnostic system and integrated process documentation. NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive. Freeware NTEdit for convenient program input via ExcelTM for WindowsTM on the PC and Freeware NTGraph for evaluation and documention of firings using ExcelTM for WindowsTM on a PC, MyNabertherm App for online monitoring of the firing on mobile devices can be downloaded for free.
