Tube furnace RSV 170/1000/11 with gas supply system 2
Quartz glass and flanges for protective gas operation as optional equipment

Nabertherm Split-Type Tube Furnace, Vertical, Gas Atmosphere or Vacuum, RSV series, 1100-1300°C

SKU: RSV series

These tube furnaces can be used for horizontal (RSH) or vertical (RSV) operation. The split-type design makes it easy to change the working tube. It allows for a comfortable exchange of various working tubes (e.g. working tubes made of different materials).

Using the wide range of accessories these professional tube furnaces can be optimally tailored to your process. By upgrading the furnaces with different gas supply systems the operation in a protective gas atmosphere, under vacuum or under flammable protective or reactive gases is possible. Besides convenient standard controllers for process control modern PLC control systems are also available.
