The HTBL furnace based on metallic materials is equipped with one heating zone (mantle heater) made from tungsten or molybdenum. The radiation shields that provide the heat insulation are constructed of the same material as the heating elements. Standard systems use nine radiation shields surrounding the heating elements. If a lower maximum temperature is required, it is possible to reduce the number of radiation shields. The HTBL, with a diameter of 400 mm and heated length of 500 mm, is well suited for high vacuum processes. Both molybdenum and tungsten exhibit very low vapor pressure even at the highest temperatures. Once the maximum temperature is achieved, the heating elements must be handled with care as they will become brittle.
All HTBL models are equipped with fully automated software and reliable data logging for later evaluation of the process. All process data are measured and logged at predefined intervals. Automated control and high volume units are especially suited for industrial applications and large scale production.
