Carbolite Gero HTRH furnaces have a choice of maximum temperature; 1600°C, 1700°C and 1800°C. There are two types of furnaces in the range.

HTRH single-zone horizontal tube furnaces with heated lengths from 100-600 mm. The maximum overall diameter of tube insert is from 40 to 200 mm.

HTRH-3 three-zone versions providing superior temperature uniformity, with heated lengths from 600 mm to 900 mm. The maximum overall diameter of tube insert is from 70 to 150mm. Each zone has its own controller and thermocouple, which is especially useful to preheat gases required for reactions inside the system.

The high-grade insulation materials guarantee low energy consumption and high heating rates due to their low thermal conductivity. The insulation and molybdenum disilicide (MoSi2) heating elements are installed in the rectangular housing. The heating elements are vertically hanging and are easily replaced. At higher temperatures and in the presence of oxygen, MoSi2 develops an oxide (SiO2) layer, which protects the heating elements against further thermal or chemical corrosion.

No integral work tube is supplied as the choice will vary depending on the application.
