The sintering furnace LT 02/13 CR is perfectly suited for sintering of cobalt-chromium restorations. The blanks are placed in a special sintering bell and will be heat-treated under argon. The specific design in combination with sintering pearls provides for good sintering results in a nearly oxygen-free atmosphere at very low argon consumption. The system is open and can be programmed for various materials up to sintering temperatures of 1300 °C. Two pre-installed sample programs, which can be adjusted individually. Furthermore, the sintering furnace LT 02/13 CR is designed for a single-phase connection.  

  • Tmax 1300 °C
  • Working temperature up to 1280 °C, depending on the CoCr material
  • Single-phase connection
  • 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). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used
  • Gas supply system with 2 solenoid valves and 2 flow meter
  • Forced cooling system with compressed air possible
  • Sintering bell with good sealing for sintering up to 30 single crowns under argon
  • Sintering pearls, Ø 1,25 mm (200 g) included in delivery scope
  • Special tongs included in the delivery scope
  • Type S thermocouple
  • Freely programmable controller C550 allows for automatic temperature control and switching of the gas flow
  • Switching system with solid-state-relays to switch the heating
  • Possibility to set two gas quantities for optimal adjustment to the sintering process
  • Controller with touch operation C550 (10 programs with each 20 segments)
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download
  • Freeware NTEdit for convenient program input via ExcelTM for MS WindowsTM on the PC
  • Freeware NTGraph for evaluation and documentation of firings using ExcelTM for MS WindowsTM on the PC
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Defined application within the constraints of the operating instructions

Additional equipment

Additional equipment

  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Process control and documentation via VCD software package for monitoring, documentation and control
