Economy Muffle Furnaces up to 1100 °C

The Nabertherm LE series muffle furnaces are the ideal solution for laboratories seeking top-tier “Made in Germany” quality with a convincing price-to-performance ratio. These compact, lightweight furnaces are engineered for fast heat-up times, making them the perfect, reliable partner for routine laboratory applications.

Unlike other furnaces, the LE series features heating elements protected inside durable quartz glass tubes, which are easy to replace. This smart design ensures robust performance and a long service life. The high-quality, non-carcinogenic (RCF-free) fiber insulation allows for exceptionally fast heating times while maintaining energy efficiency. A dual-shell housing made of textured stainless steel ensures low external surface temperatures through fan cooling.

Standard Equipment:

• “Made in Germany” Quality: Engineered and manufactured by Nabertherm for maximum reliability.
• Max Temperature: 1100 °C.
• Fast Heating: Achieves 1000 °C in as little as 10 minutes (LE 1/11 model).
• Protected Heating: Heating from two sides with elements protected in quartz glass tubes.
• Flap Door: A robust flap door is standard, which can be used as a work platform.
• Durable Housing: Dual-shell housing of textured stainless steel with fan cooling for low surface temperatures.
• Advanced Insulation: Uses high-quality, non-categorized fiber insulation (RCF-free).
• Venting System: Includes an exhaust air outlet in the rear wall of the furnace.
• Compact Controller: Controller R8 (with one storable program) is mounted under the door to save space.
• Quiet Operation: Uses solid-state relays for low-noise heating operations.

Applications in Your Industry:

The LE series is a perfect entry-level furnace for ashing and quality control tests in demanding industrial labs:

• Polymer & Rubber Industry: Ideal for loss on ignition (LOI) to determine filler and ash content of raw materials or finished products.
• Pipe & UPVC Profile Industry: Used for daily QC checks to determine the ash content (filler, TiO2) of UPVC or the carbon black content of PE pipes.
• Packaging & Disposable Containers: Provides simple, fast ashing to check filler content in plastic films and containers.

Customize your Nabertherm LE muffle furnace to match your laboratory’s specific processes with these optional accessories.

Available Options & Accessories:

• Exhaust & Venting: Upgrade your ventilation with an exhaust chimney, a chimney with an integrated fan, or a catalytic converter to handle process-related fumes. (Note: These options are not available for LE 1/11 and LE 2/11 models).
• Multi-Level Charging Rack: For efficiently loading multiple samples, a charging rack for two levels is available for the LE 14/11 and LE 24/11 models. This includes a holder for easy insertion and removal.
• Advanced Controller: While the R8 is standard, this furnace can be equipped with more advanced Nabertherm controllers for multi-segment programming (e.g., B510 or C550). Contact us to discuss your process requirements.
