The HTBL MO / HTBL W is a bottom loading furnace system that is based on metallic insulation and heating elements. The metallic furnaces are offered with a volume of 60 litres. The HTBL 60 MO/16-1G has a maximum temperature of 1600 °C and uses molybdenum radiation shields and heating elements. The HTBL 60 W/22-1G has a maximum temperature of 2200 °C and uses tungsten radiation shields and heating elements. The metallic versions of the HTBL are suited for generating the purest atmospheres and the best working vacuum level. One clear advantage is the easy loading and unloading of the HTBL type furnaces. Once the hearth has been lowered, the sample is accessible from all sides without limitations. Sample loading is extremely easy and user-friendly, especially with delicate samples. Additionally, sample thermocouples can placed at specified locations within the chamber. A retort may also be used with the HTBL. The movement of the loading area is fully automated and driven by a hydraulic arm. Once the loading area has reached the lowest position, the user can manually rotate the loading platform outward by 90 °. Nitrogen, Argon, and Hydrogen gases are available for use as either pure or mixed gas. Other gases may be installed upon request. A slight overpressure or controlled partial pressure, to establish a defined gas flow, can be used in the furnace. Operation with air is not possible. Various dosing and controlling devices control all gases. Depending on the vacuum requirements, vacuum pumps are configured specifically for the application or as requested. The temperature is independently controlled to achieve the best uniformity.
