KNC/V vertical chamber furnace with forced circulation up to 650 / 850 °C

Meets even the very strict demands of the DIN, AMS, and CQI standards

We recommend the KNC/V furnaces for heat treatment under a normal atmosphere, which is demanding in terms of precise temperature distribution and a dynamic course of the temperature curve. If you need, we will adapt your furnace so that it meets the demands of the strict DIN 17052-1, AMS 2750e, or CQI-9 standards.
