The LH 15/12 - LF 120/14 chamber furnaces have been trusted for many years as professional chamber furnaces for the laboratory.

• Tmax 1200, 1300, or 1400 °C
• Dual shell housing with rear ventilation, provides for low shell temperatures
• Five-sided heating for very good temperature uniformity
• Heating elements on support tubes ensure free heat radiation and a long service life
• Controller mounted on furnace door and removable for comfortable operation
• Protection of bottom heating and flat stacking surface provided by embedded SiC plate in the floor
• LH models: multi-layered, fiber-free insulation of light refractory bricks and special backup insulation
• LF models: high-quality non-classified fiber insulation with corner bricks for shorter heating and cooling times
• Door with brick-on-brick seal, hand fitted
• Short heating times due to high installed power
• Self-supporting arch for high stability and greatest possible protection against dust
• Quick lock on door
• Motor driven exhaust air flap
• Freely adjustable air slide intake in furnace floor
• Base included
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

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.
