Chamber Furnaces with Drawer Bottom or as a Bogie

Chamber furnace NW 440 with free traversing bogie Chamber furnace NW 300 with pulled-out furnace table

The NW chamber furnaces enable simple charging for cold-cold processes. The heat treatment can take place under air or under non-flammable protective gases with a protective gas box or protective gas hood. With a drawer mechanism (NW 150 - NW 300/H) the furnace table can be easily pulled out of the chamber furnace. The larger models NW 440 - NW 1000/H are designed as shuttle furnace with completely free traversing bogie. Free access in front of the furnace allows for a simplified and clear charging.

  • Tmax 1300 °C, 1100 °C with protective gas box (additional equipment)
  • Dual shell housing, galvanized steel sheets
  • Double-walled door with front made of textured stainless steel
  • Controller mounted on furnace door and removable for comfortable operation (up to model NW 440)
  • Heating from five sides with special arrangement of heating elements for optimum temperature uniformity
  • Heating elements of support tubes provide for free radiation of the heat
  • Multi-layer insulation with light-weight refractory bricks and high-quality, energy-saving backing insulation
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Vaulted ceiling
  • Furnace table can be pulled-out as drawer (NW 150 - NW 300)
  • From chamber furnace NW 440 bogie on four castors (two with brakes) which can be pulled out completely. Accession assistance and removable drawbar for bogie
  • SiC-floor plate protects floor elements and provides a level setting surface
  • Door sealing grinded by hand (brick on brick); NW 150 - NW 300
  • Semi-automatic air inlet flap closes the air inlet at a temperature which can be set in the controller for NW 150 - NW 300
  • Exhaust air outlet in the ceiling, motor driven exhaust air flap for chamber furnaces NW 440 - NW 1000
  • Comfortable charging height with base of 800 mm (chamber furnaces NW 440 - NW 1000 = 500 mm)
  • Defined application within the constraints of the operating instructions
  • NTLog for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

  • Protective gas boxes and hoods
  • Manual or automatic gas supply system
