Annealing and Hardening Furnaces with Wire Heating, Preheating Furnaces for Molds

N 41/H N 312

N 7/H

Production moulds for beer glasses

N 7/H - N 641/13

The models N 31/H ff. have been specially developed for preheating of moulds but also for hardening jobs when toolmaking.

  • Compact, robust design
  • Three-sides heating: from both side walls and floor
  • High-quality, free-radiating heating elements mounted on support tubes for longest service life
  • Bottom heating protected by heat conducting SiC tiles
  • Parallel guided downward swinging door (user protected from heat radiation)
  • Stainless steel upper door jamb protects furnace structure when furnace is opened hot
  • Exhaust opening in the side of the furnace, or on back wall of furnace in the N 31/H models and higher
  • Temperature uniformity up to ∆T 20 K according to DIN 17052-1
  • Low energy consumption due to multi-layer insulation
  • Gas spring dampers provide for easy door opening and closing
  • Heat resistant zinc paint for protection of door and door frame (for N81 and larger)
