KNC/H horizontal chamber furnace with forced circulation up to 650 / 850 °C

Ideal in situations where there are strong demands for even temperature distribution

The chamber furnaces with forced air circulation are used for all types of heat treatment (tempering, artificial ageing, preheating, hot connecting, charge testing, drying out, etc.) under normal atmosphere, where demand exists for very precise temperature distribution and a dynamic course of the temperature curve.
