New

These compact bench-top furnaces with lift door are now also available with 60 liters volume for maximum temperatures of 1100 °C.
Equipped with three-side heating they provide an excellent temperature uniformity of +/- 5 K in the empty working space at temperatures above 800°C.
Connected at three phase 400 V 3/N/PE, the combination of dual shell housing and superior insulation materials results in less power consumption.

Standard Equipment

• Tmax 1100 °C or 1200 °C
• Heating from two sides by ceramic heating plates (heating from three sides for muffle furnaces L 24/11 – LT 60/12) 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
• Thermocouple type N (1100 °C) or type S (1200 °C)
• Ceramic heating plates with integral heating element which is safeguarded and easy to replace
• Optional flap door (L) which can be used as work platform 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

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.

To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The chamber furnaces
N 7/H – N 87/H are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation
under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical
applications can be implemented without the use of expensive and complicated annealing systems.

Standard Equipment
· Tmax 1280 °C
· Deep furnace chamber with three-sides heating: from both side walls and bottom
· Heating elements on support tubes ensure free heat radiation and a long service
life
· Bottom heating protected by heat-resistant SiC plate
· Temperature uniformity up to +/− 10 °C according to DIN 17052-1
· Low energy consumption due to multi-layer insulation
· Base frame included in the delivery, N 7/H – N 17/HR designed as table-top
model
· Parallel guided downward swinging door (user protected from heat radiation)
· Door movement cushioned with gas dampers/struts
· Controller B400 (5 prgrams with each 4 segments)
