Nabertherm Compact Preheating Oven with Hinged Door

Nabertherm Compact Preheating Furnace with Hinged Door

The Nabertherm Compact Preheating Furnace with Hinged Door is a modern precision device for dental laboratories, specially designed for the safe and efficient preheating of muffles, dental materials or other laboratory materials. Its robust construction, first-class temperature accuracy and innovative digitalisation make it the first choice for professionals in the dental technology sector. In direct comparison to conventional preheating furnaces, this model offers a particularly fast heating time, additional data processing features and reliable compliance with safety and quality standards.

Efficient technology and reliable materials

The innovative furnace technology is based on a double-walled stainless steel construction with internal heating elements made of quartz glass. This ensures extremely even temperature distribution, while the external temperature remains low, making everyday laboratory work safer. High energy efficiency combined with low-noise semiconductor relays ensures quiet and trouble-free operation - even during prolonged use. Another outstanding feature is the flexible model selection with different chamber sizes from 1 to 24 litres, so that every application can be optimally covered, from small specialised laboratories to large-scale operations. Each model variant offers: Maximum temperature: 1,100 °C - ideal for burning out muffles and other dental technology processes. Fast heating times: Between 10 and 40 minutes to operating temperature, depending on the model.

The following technical details are also impressive:

• Internal dimensions optimally matched to standard muffles, depending on the model.
• External housing with special ventilation to reduce heating of the working environment.
• Temperature selector limiter as protection against overheating.

The extensive digital functions are a particular highlight: the free MyNabertherm app allows the firing process to be monitored and documented online - conveniently via smartphone or tablet. The freeware NTEdit facilitates programming and data transfer, while NTGraph and NTLog Basic offer comprehensive evaluation and documentation options.

Certifications and standards

The preheating furnace meets the requirements of EN 60519-2 (safety of electrical resistance heating equipment) and is also EC-compliant in accordance with EC Regulation No. 1272/2008 (CLP) for processed materials. The integrated temperature selector limiter ensures maximum safety and provides reliable protection against overheating.

Specific application examples

• Burning out dental laboratory muffles: Especially for casting processes where wax residues must be removed and muffles brought to the final temperature. In this case, non-combustible reaction or protective gases (e.g. nitrogen, argon) are often introduced via an optional gas connection.
• Preheating of investment materials: Suitable for silicate, phosphate and zirconium oxide-based materials and common processes in accordance with EC Regulation 1272/2008 (CLP).
• Heat treatment of dental alloys: Thermal tempering and regeneration of various metals and alloys, such as CoCr or titanium-based substances.
• Heating and calcination of ceramics and glasses: For special laboratory processes with dental ceramics or glass-ceramic materials.

  The furnace is not only designed for use with standard products, but also proves its worth in applications where a fast temperature ramp and precise control are essential.

  FAQs

  Which models are available and how do they differ?

  • LE 1/11: 1 litre volume, compact dimensions (90 x 115 x 110 mm), particularly short heating time (10 minutes).
  • LE 2/11: 2 litres, slightly larger chamber, 15-minute heating time.
  • LE 6/11: 6 l, generous working space, 30 min heating time.
  • LE 14/11: 14 l, especially for large series, 35 min heating time.
  • LE 24/11: 24 l, maximum capacity, 40 min heating time.

  Is the furnace chamber quiet during operation?

  Thanks to precise control via a powerful semiconductor relay, the heater runs almost silently - ideal for quiet working in the dental laboratory.

  Which materials and substances can be treated?

  All materials classified in accordance with EC Regulation No. 1272/2008 may be used. Aluminium silicate wool and RCF fibres are excluded.

  Are there any special safety precautions?

  Yes, the temperature selector limiter reliably prevents the furnace from overheating. In addition, the double-walled construction ensures low external temperatures and thus greater protection for personnel.

  How can I document and evaluate process data?

  The MyNabertherm app, NTEdit and NTGraph provide professional tools for documentation, remote monitoring and analysis. Optionally, the data can be stored on a USB stick.

  Is the device available with a catalyst or protective gas connection?

  A catalyst module (e.g. for wax burnout), a protective gas connection and a fan for exhaust air extraction can be ordered as options.

  For which mains voltages is the furnace available?

  All model variants can be supplied for mains voltages from 110 V to 240 V at 50 or 60 Hz.
