The LH 15/12 - LF 120/14 laboratory furnaces 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 fibre material (LF models). With a wide variety of optional equipment, these models can be optimally adapted to your processes. Tmax 1200 °C, 1300 °C or 1400 °C 5-sided heating for very good temperature uniformity Heating elements on support tubes ensure free heat radiation and a long service life Protection of floor heating and flat stacking surface provided by embedded SiC plate in the floor LH models: multilayered, fibre-free insulation of light refractory bricks and special backup insulation LF models: high-quality fibre 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 Side vent with bypass connection for exhaust pipe Self-supporting arch for high stability and greatest possible protection against dust Quick lock on door Freely adjustable air slide intake in furnace floor Stand included For control system see page 42
