Chamber Furnaces with Radiation Heating

N 7/H N 41/H

N 641 with annealing box and lift trolley

N 7/H - N 1491

These universal chamber furnaces with radiation heating are designed for highly adverse conditions during heat treatment. They are ideally suited for tooling construction processes and in the hardening shop, such as annealing, hardening or preheating for forging. The use of various accessories allow these furnaces to be modified for your application.
