6-SL-Series

The Linn High Temp – 6-SL Series is a gastight double annealing muffle furnace designed for controlled atmosphere applications, operating at temperatures up to 650 °C. It features vacuum-formed ceramic fibre half shells for high-efficiency insulation and is equipped with FeCrAl wire heaters embedded in the insulation for uniform and reliable heating. Temperature is precisely monitored using a Type K (NiCr/Ni) thermocouple.

The system includes two gastight muffles with forced convection, enhancing heat transfer and ensuring excellent temperature uniformity. With a diameter of 270 mm and a heated length of 450 mm, the furnace is also integrated with dedicated heating and cooling stations, making it ideal for fast, efficient annealing cycles in both laboratory and production environments.
