L 3/11 - L 40/11 muffle furnaces are the ideal choice for daily laboratory use. These high quality models have an advanced and attractive design, are very reliable and have a fold-down door as standard.

• Textured stainless steel housing
• Dual-shell housing for low external temperatures and high stability
• Fold down door (L models) can be used as a work platform
• Exhaust air outlet on the rear wall of furnace
• Solid state relays provide low noise operation
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: Recording of process data with USB flash drive

Heating is from two sides by means of ceramic heating plates (heating from three sides for muffle furnaces L 24/11 - L 40/11). These ceramic heating plates with an integral heating element are protected from fumes and splashing, and are easy to replace. Only fibre materials which are not classified as carcinogenic according to TRGS 905, class 1 or 2 are used.

The furnace is equipped with a B 510 standard controller with touch screen display, featuring five freely adjustable programs, four segments and two extra functions. These controllers are PID microprocessor controlled with a self-diagnostic system and integrated process documentation. B 510 controllers can automatically activate the vent with fan or catalyst (not model L 15).
