Nabertherm Compact Tube Furnace RD-Series

Compact Tube Furnaces up to 1100 °C

The RD 30/200/11 tube furnace impresses with its very good price-performance ratio, particularly compact external dimensions and its low weight. This all-rounder is equipped with a working tube, which also serves as support for the heating wires. The working tube is therefore part of the furnace heating, with the advantage that the tube furnace reaches very high heating speeds. The furnace is designed for horizontal use up to 1100 °C.

Standard Equipment

• Tmax 1100 °C
