2.2. Process defined by Nabertherm
• The furnace can be opened and loaded / unloaded both, in cold and hot condition
• Heating elements only active if furnace is closed
• This kind of furnace runs typically on one holding temperature in continuous mode. Of course different profiles can be run according to the type of controller and the physical characteristics of furnace and charge.
• Loading / unloading: manual or with forklift
3. Defined application
• For thermal processes where the loading and unloading will be carried out up to Tmax
• Furnace suitable for continuous operation
• Furnace can also be used for temperatures below the temperature operating range, but with restrictions regarding temperature- uniformity and control- accuracy.
• Loading/ unloading: manual or with forklift from the front
• To be used for processes with no generation of explosive gas atmospheres as a result of exhaust gases, vapours, or other combustible substances from the charge or test material.
• To be used for processes with no use generation of hazardous substances which require additional protective measures.
• No thermal processes with uncontrolled chemical or thermodynamic reactions.
• For thermal processes which do not require clean oven atmospheres
• Not useful for food heating

6.4. Gas management system
No gas management system included (see additional equipment)
6.5. Protective gas box/ Annealing box
• No Protective gas box/ Annealing box included, (see additional equipment)
• Ovens with gassing boxes are characterized by a very good price / performance ratio. In gas boxes, good heat treatment results under protective gas can be achieved, which are sufficient for many requirements. If the charge requires a completely oxygen-free atmosphere, retort furnaces can be offered. In this case we will be pleased to send you an alternative offer
• Note:
Wear parts made of metal inside the furnace such as muffles, insert boxes, roller conveyors, charging plates or sheet metal linings are subject to increased wear depending on the respective use. In addition to the process and the type of application, the service life also depends on the frequency of use. There may be distortion of these components. A slight deformation is normal and requires no further measures. However, if larger distortions occur, rework or replacement of the component is recommended. A regular check of the functionality by the customer is recommended.
