The muffle furnaces L 1/12 - LT 40/12 have been proven for daily laboratory use. These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. The muffle furnaces come equipped with either a flap door or lift door at no extra charge. Standard Equipment • Heating from two sides by ceramic heating plates (heating from three sides for muffle furnaces L 24/11 - LT 40/12) for an optimal temperature uniformity • Temperature uniformity of +/− 5 K with closed fresh-air inlet in empty work space according to DIN 17052-1 at working temperatures above 800 °C • Ceramic heating plates with integral heating element which is safeguarded and easy to replace • Optional flap door (L) or lift door (LT) with hot surface facing away from the operator • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature • Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP) • Adjustable air inlet integrated in door (see illustration) • Exhaust air outlet in rear wall of furnace • Controller B510 resp. R7 for L 1/12 (5 programs with each 4 segments) • Solid state relays provide for lownoise operation • Defined application within the constraints of the operating instructions • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
