LH models: multi-layered insulation of light refractory bricks and special backup insulation.

LF models: high-quality fiber insulation with corner bricks for shorter heating and cooling times.

These big chamber furnaces LH 15/12 - LF 120/14 have been trusted for many years as professional chamber furnaces for the laboratory. These furnaces are available with either a robust insulation of light refractory bricks (LH models) or with a combination insulation of refractory bricks in the corners and low heat storage, quickly cooling fiber material (LF models). With a wide variety of optional equipment, these chamber furnaces can be optimally adapted to your processes.

Standard Equipment

  • Tmax 1200 °C, 1300 °C, or 1400 °C
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
