Vacuum heat treatment furnaces type VWC can be used for a variety of heat treatment processes such as for example low carburizing, hardening, tempering, annealing or brazing. In this furnace with cylindrical heating chamber the usable space consists of a graphite cylinder in which are located curved graphite heating elements. Compared to conventional polygon segments significantly fewer fasteners are needed, which represent thermal bridges. Thus up to 20% less energy is required for heating. The cylindrical chamber design is advantageous for the charging of components whose dimensions are partially outside the specified work space. The quenching gas is directed through nozzles at the cylinder wall radially on the batch and then guided axially rearwardly to a copper heat exchanger.
