Tempering can be done in a separate furnace or in a downstream module. By choosing the module the customer saves production space and investment costs because the module doesn’t need additional loading and unloading table, belt drive, and so on.

Characteristics and advantages

• Working temperatures up to 650 °C
• Electrically or gas heated
• Operated with protective gas or air
• With or without muffle
• With or without recirculation
• Cooling possible (to be used as cooling zone)

The convective 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.

Characteristics and advantages

• Convective cooling by circulating the protective gas
• Shorter cooling times shorten the furnace length
• Good accessibility to the heat exchangers
• Increased process stability due to stable gas flow
• Compensation of turbulences resulting from gas quenching

As an option we offer the furnaces with a visualisation system. As hardware, a PC with Windows operating system and a visualisation program compatible with Windows. This system mainly monitors and records continuously the most important process parameters. Since this system only supplements the hardware of the standard control system, it is possible to operate the furnace even when the furnace fails.

Characteristics and advantages

• Display, setting and storage of operation parameters
• Administration of recipes
• Alarm diagnosis with possible cause of malfunction
• Timer function
• Furnace book
• Modem/network connection: remote diagnosis to check and clear malfunctions
• Maintenance list with memory function
