High-quality insulation materials made of vacuum-formed fiber 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 non-flammable or flammable protective or reactive gases or under vacuum.

: Optional accessories include: Charge control with temperature measurement in the working tube and in the furnace chamber outside the tube; display of inner tube temperature with additional thermocouple; gas tight flanges for protective gas and vacuum operation; manual or automatic gas supply system; three-zone control for optimization of temperature uniformity (only RHTH tube furnaces); check valve at gas outlet avoids intrusion of false air; alternative working tubes designed for process requirements; process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control. Contact your Avantor representative for more information.
