These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. Heating elements on support tubes radiating freely into the furnace chamber provide particularly short heating times and a maximum temperature of 1400 °C. These muffle furnaces are a good alternative to the LT series when higher application temperatures are required.

• Heating from two sides
• Heating elements on support tubes ensure free heat radiation and a long service life
• Only fibre materials which are not classified as carcinogenic according to TRGS 905, Class 1 or 2 are used
• Dual shell housing for low external temperatures and high stability
• Fold down door (L) which can be used as a work platform
• Exhaust air outlet on rear wall of furnace
• Solid state relays provide low-noise operation

The furnace is equipped with B510 standard controller with touch screen display, featuring 5 freely adjustable programs and 4 segments and 2 extra functions. These controllers are PID microprocessor controlled with a self-diagnostic system and integrated process documentation. The B510 controllers can automatically activate the vent with fan or catalytic converter (not model L 15).
