High-temperature chamber furnaces with air circulation NA / NAT

Description
These chamber furnaces with air circulation are characterized by their extremely high temperature uniformity. Hence, they are especially suitable for processes such as cooling, 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.

  • Tmax 450 °C, 650 °C, or 850 °C

  • Horizontal air circulation

  • Swing door hinged on the right

  • Temperature uniformity up to ±4 °C according to DIN 17052-1 (model NA 15/65 and NAT 30/85 up to ±5 °C)

  • Optimum air flow and temperature uniformity through high circulation rates

  • One frame sheet and rails for two additional trays included in the scope of delivery (NA 15/65 and NAT 30/85 without frame sheet)

  • Stainless steel air-baffles in the furnace for optimum air circulation

  • Base frame included in the delivery, NA 15/65 and NAT 30/85 designed as table-top model

  • Air inlet and exhaust air flaps as additional equipment for using as drying oven

  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

  • Available with the programmable controllers B 500 and C 540 with adjustable ramps and hold times (NA 15/65 with B 510 or C 550)

  • Standard power supply 400 V 3/N/PE 50/60 Hz (NA 15/65: 220 - 240 V, 1/N/PE)
