Convective cooling zone with gas flow control (GSR)
The conective cooling zone essentially reduces the cooling time of the parts. Thus the whole cooling zone is shorter, and, subsequently, the overall length of the furnace itself.
The automatic gas flow control regulates the distribution of the protective gas inside the furnace and protects the parts and the furnace from outside air. There is no need to set or adjust the gas flow manually. A gas flow control is especially useful and recommendable with a gas quench system with its accompanying gas turbulences.
