HIGH TEMPERATURE TUBE FURNACE RHTV 80/30

The high-temperature tube furnaces are available in either horizontal (type RHTH) or vertical (type RHTV) designs. High-quality insulation materials made of vacuum-formed fibre plates enable energy-saving operation and a fast heating time due to low heat storage and heat conductivity. By using different gas supply systems, operations can be performed under a protective gas atmosphere, vacuum, or even with flammable gasses.

Dimensions without tube.

Option:

• Charge control with temperature measurement in the working tube and in the oven chamber behind the tube
• Alternative working tubes designed for process requirements
• Display of inner tube temperature with additional thermocouple
• Gas-tight flanges for protective gas and vacuum operation
• Manual or automatic gas supply system
• Three- or five-zone control for optimization of temperature uniformity
• Check valve at gas outlet avoids intrusion of false air
