Forced Convection Chamber Furnace NA500/45 with B500 Controller 480V

These chamber furnaces with air circulation are characterized by their extremely high temperature uniformity. Hence, they are especially suitable for processes such as annealing, crystalizing, preheating, curing, but also for numerous processes in tool making. Due to the modular concept, the forced convection furnaces can be adjusted to the process requirements by adding suitable equipment.

Standard Equipment

• Tmax 450 °C, 650 °C, or 850 °C
• Horizontal air circulation with optimum distribution through stainless steel baffles
• Swing door hinged on the right
• Temperature uniformity up to +/− 4 °C according to DIN 17052-1 (NAT 15/65 and NAT 30/85 up to +/− 5 °C) in the empty work space
• One frame sheet and rails for two additional trays included in the scope of delivery (NAT 15/65 and NAT 30/85 without frame sheet)
• Base frame included in the delivery, NAT 15/65 and NAT 30/85 designed as table-top model
• Controller B400/B410 (5 programs with each 4 segments)
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional Equipment

• Optimization of the temperature uniformity up to +/− 3 °C according to DIN 17052-1 in the empty work space
• Air inlet and exhaust air flaps when used for drying
