Overview
The LT 02/13 CR sintering furnace is designed for sintering cobalt‑chromium restorations in an argon atmosphere. Blanks are placed in a sealed sintering bell and heat‑treated under controlled gas flow. The combination of the furnace design and sintering pearls enables effective sintering in a nearly oxygen‑free atmosphere with low argon consumption. The open system is freely programmable and suitable for various CoCr materials up to sintering temperatures of 1280 °C. Two sample programs are preinstalled. The unit is configured for single‑phase electrical connection.

Function and equipment

• Tmax 1300 °C
• Working (sintering) temperature up to 1280 °C (material dependent)
• Sealed sintering bell for sintering up to 30 single crowns under argon
• Single‑phase electrical connection (1‑phase)
• Double‑shell housing in textured stainless steel with additional fan cooling to keep low surface temperatures
• Insulation materials without classification per EC Reg. 1272/2008 (no RCF used)
• Gas supply with 2 solenoid valves and 2 flow meters; possibility to set two gas flow quantities
• Forced cooling with compressed air possible (rapid cooling option)
• Sintering pearls Ø 1.25 mm (200 g) and special tongs included
• Type S thermocouple
• Freely programmable C550 touch controller (10 programs × 20 segments) with automatic temperature control and gas switching
• Solid‑state relays for heating control
• MyNabertherm App for mobile online monitoring; NTEdit/NTGraph/NTLog Basic support for program input, evaluation and data logging

Additional equipment

• Over‑temperature limiter with adjustable cutout temperature to protect furnace and load
• Process control and documentation via VCD software package (monitoring, documentation, control)
