Technical features and advantages for professional use

The mechanical engineering and laboratory technology industries will find a wide range of performance features in this device that are specifically tailored to industrial testing requirements, materials science tasks and routine laboratory work:

• Maximum temperature: 1400 °C - fast and safe reaching of maximum temperature ranges, ideal for complex thermal processes.
• Fibre insulation: Particularly energy-efficient, reduces heat loss and enables rapid heating times.
• Uniform heating: Heating elements installed on both sides of the support tubes ensure homogeneous temperature distribution and a long service life.
• Double-walled stainless steel housing: Ensures low external temperatures, protects users and provides increased stability.
• Flexible door design: Lift door with adjustable air inlet for convenient loading and effective ventilation during operation.
• Intuitive control: Up to five programmes with four segments each, operated via a clearly structured controller.
• Innovative data recording: Process data can be conveniently stored and analysed via NTLog Basic and USB interface.

The most important technical specifications of the available models:

• Volume/capacity: optionally 5, 9 or 15 litres for different sample quantities.
• Internal dimensions (W x D x H):
  • LT 5/14: 200 x 170 x 130 mm
  • LT 9/14: 250 x 250 x 170 mm
  • LT 15/14: 250 x 350 x 170 mm
• External dimensions including open lift door: Starting from 490 x 450 x 580+320 mm (depending on model).
• Connected load: 2.4-3.2 kW, for 1-phase connection 110-240 V, 50/60 Hz, flexibly adjustable.
• Heating time to Tmax: approx. 50-70 minutes, depending on model.
• Weight: 42-63 kg, easy to transport and robust.
• Heating: Low-noise via semiconductor relay.

Special attention has been paid to the fibre insulation used, which does not contain any materials subject to the CLP Regulation, thus fully complying with both environmental and health requirements.

Certifications and standards

The oven is manufactured in accordance with all relevant European standards and directives, including Regulation (EC) No. 1272/2008 (CLP). This guarantees the highest safety standards and long-term environmentally friendly use in laboratory and industrial operations. Appropriate CE marking and comprehensive protection systems are a matter of course.

Practical applications

Thanks to its flexible control system and first-class insulation technology, this system is suitable for a wide range of applications where precise temperature settings and controlled atmospheres are essential. The most important areas of application include:

• Heat treatment and materials testing: Suitable for annealing, sintering and tempering tests on metals and ceramics, including special alloys, aluminium oxide, silicon carbide and titanium.
• Laboratory analysis: Perfect for ash content analysis, burning out organic components in samples (incineration), e.g. in environmental, feed or chemical samples.
• Research and development: Development of new materials or formulations, for example for the dental, electronics or special glass industries.
• Quality assurance: Fast-heating furnaces for routine control tests and production validation in technical ceramics, powder metallurgy and firing technology.

In addition, the furnace can be used for organic and inorganic material conversions, thermogravimetric investigations, and oxidation and reduction experiments.

FAQs on professional operation

How long does it take to heat up to the maximum temperature?

• Depending on the model, the heating time to 1400 °C is 50 to 70 minutes with an empty furnace. For frequent process changes, we recommend the LT 5/14 or LT 9/14 model.

Are there any special safety precautions?

• The double-walled housing minimises the surface temperature. No materials containing substances subject to labelling requirements are used in the insulation. Operation is exclusively with a closed system, which provides optimum protection for the operator. The instructions for use and protective measures in the operating manual must be observed.

What holding times is the device designed for?

• Continuous holding times at a maximum of 1300 °C are recommended, as this optimises the service life of the heating elements. A short-term maximum temperature of 1400 °C is possible.

What voltages are permitted for operation?

• All models are designed for international use: 110-240 V, 1-phase, 50 or 60 Hz. This allows flexible adaptation to different laboratory and production locations.

Conclusion

The Nabertherm muffle furnace with fibre insulation and lift door impresses with its advanced heating technology, practical functionality and outstanding safety, specially tailored to professional requirements in the laboratory and industrial sectors. Its variable equipment, high energy efficiency and compliance with European environmental and safety standards make it the first choice for demanding heat treatment and analysis processes in research, development and quality assurance.
