Presented are muffle furnaces of many models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. The muffle furnaces are supplied with a flap or lift door (optional) and without extra charge. Tmax up to 1300 ° C

These furnaces are especially used for the assay of precious metals and ashing processes where the insulation and heating must be protected from emerging gasses and vapours. The furnace chamber forms a ceramic muffle which can easily be replaced. The assay furnace is equipped with an integrated exhaust hood above the furnace door for connection to and exhaust sytem.

The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quench tank. Use it for annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.

These furnaces are available with either a robust insulation of light refractory bricks (LH models) or with a combination insulation of refractory bricks in the corners and low heat storage, quickly cooling fiber material (LF models).

For temperatures up to 1400 ° C, 1500 ° C, 1550 ° C, 1600 ° C, 1700 ° C, 1750 ° C, 1800 ° C.
Heating times of 40 minutes to 1400 °C can be achieved, depending on the furnace model and the conditions of use.

They are especially suitable for processes such as cooling, crystalizing, preheating, curing, but also for numerous processes in tool making. Tmax 300 °C, 450 °C, 650 °C, or 850 °C

Options: Furnace Installation in the Clean Room; Furnace Installation in the Grey Room, Furnace Charging from the Clean Room; Sluice Furnace between Grey Room and Clean Room. Please contact us if you are looking for a heat treatment solution under clean room conditions. We would be pleased to quote for the oven or furnace model that meets best your requirements.

Compact, With Stand for Horizontal or Vertical Operation, High-Temperature with SiC Rod Heating, Including Gas Atmosphere or Vacuum, For Horizontal and Vertical Operation up to 1800 °C, Split-Type up to 1300 °C, Rotary for Batch Operation up to 1100 °C, Rotary for Continuous Processes up to 1300 °C

With their high level of flexibility and innovation, Nabertherm offers the optimal solution for customer-specific applications. Based on our standard models, we develop individual solutions also for integration in overriding process systems.

The practical counter balanced hinge with shock absorbers and the spout (not for KC) on the front of the furnace make exact dosing easy when pouring the melt. The melting furnaces are available for furnace chamber temperatures of 1000, 1300, or 1500 °C. This corresponds to melt temperatures of about 80 °C - 110 °C lower.

The combination of high performance, low thermal mass and powerful cooling fans provides for cycle times from cold to cold up to 35 minutes with an opening temperature of approx. 300 °C.

The temperature in each of the six heating zones is separately controlled. The gradient furnace is usually charged from the side through the parallel swivel door. A maximum temperature gradient of 400 °C can then be stabilized over the heated length of 1300 mm.

Are equipped with direct or indirect heating depending on temperature. They are perfectly suited for various heat treatment processes requiring a defined protective or a reaction gas atmosphere. These compact models can also be laid out for heat treatment under vacuum up to 600 °C.
