0 out of 5
(0)
SKU: N/A

The CWF range of general purpose laboratory chamber furnaces is bench mounted. Models are available in five sizes with a maximum operating temperature up to 1300 °C.

The airflow in the CWF-B furnaces is enhanced by the addition of air inlet holes in the door and a tall chimney which rapidly removes the fumes from the furnace.

The CWF-BAL furnace with integral balance can be used for thermogravimetric analysis (TGA) and loss on ignition (LOI) applications, where weight change of the sample must be monitored during the heating process. This is required, for example, in the determination of inorganic matter content in materials such as cement, lime, calcinated bauxite and refractories. For applications involving organic matter content, please refer to the AAF-BAL.

Carbolite Tube furnace with eight zones – AZ

SKU: N/A

The AZ is an eight zone tube furnace for controlled temperature profiles. These zones can be used to generate temperature profiles along the heated length of the furnace. 

With eight zones, thick insulation, and highly symmetrical winding of the heating elements throughout the entire AZ furnace, a uniformity of better than ± 5 °C is achieved. A key advantage of the eight individually controlled zones is the extension of the uniform length inside the furnace. Additionally, the temperature profile can be precisely controlled for linear increases, peaks, or other user defined profiles.

One process well suited for the AZ tube furnace is chemical vapour deposition as a temperature gradient can be established in the furnace for evaporation of precursor material at the high temperature end zone and sublimation of the vapour onto the substrate at the cooler temperature end zone. All zones are individually controlled and monitored with thermocouples.

SKU: N/A

The Carbolite Gero high temperature tube furnaces HTRH can be used horizontally up to 1800 °C. 

The high-grade insulation materials guarantee low energy consumption and high heating rates due to their low thermal conductivity. The insulation and molybdenum disilicide (MoSi2) heating elements are installed in the rectangular housing. The heating elements are vertically hanging and can be replaced easily. At higher temperatures and in the presence of oxygen, MoSi2develops an oxide (SiO2) layer, which protects the heating elements against further thermal or chemical corrosion.

Three-zone tube furnaces (HTRH-3) can achieve better temperature uniformity than single-zone versions. In these models each zone is equipped with a dedicated thermocouple and controller, which is especially useful to preheat gases required for reactions inside the system.

The HTRH tube furnaces do not include an integral work tube. The work tube must be selected as an additional item. The work tube length is dependent on the application and will vary if used with or without modified atmosphere or vacuum.

(0)

The MTF wire wound tube furnaces, like the larger diameter CTF range use a wire element that is wound directly onto a fixed integral ceramic work tube.

This simple and economical design provides a furnace which can be used without the need to purchase an accessory work tube.

However, should vacuum or a modified atmosphere be required, it is necessary to use a separate slide-in work tube in order to provide the required length needed to fit end seals. Similarly, in some circumstances a work tube that has different physical or chemical properties to the fixed work tube may be required.

The use of an additional slide-in work tube protects the integral work tube and heating element.

Carbolite Tube furnace with eight zones – AZ

0 out of 5
(0)

The AZ is an eight zone tube furnace for controlled temperature profiles. These zones can be used to generate temperature profiles along the heated length of the furnace. 

With eight zones, thick insulation, and highly symmetrical winding of the heating elements throughout the entire AZ furnace, a uniformity of better than ± 5 °C is achieved. A key advantage of the eight individually controlled zones is the extension of the uniform length inside the furnace. Additionally, the temperature profile can be precisely controlled for linear increases, peaks, or other user defined profiles.

One process well suited for the AZ tube furnace is chemical vapour deposition as a temperature gradient can be established in the furnace for evaporation of precursor material at the high temperature end zone and sublimation of the vapour onto the substrate at the cooler temperature end zone. All zones are individually controlled and monitored with thermocouples.

The TZF 3-zone high temperature tube furnace has heated lengths of 450 and 610 mm. An extended uniform zone in the mid-section of the work tube is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.

Carbolite High Temperature Horizontal Tube Furnace – HTRH

0 out of 5
(0)

The Carbolite Gero high temperature tube furnaces HTRH can be used horizontally up to 1800 °C. 

The high-grade insulation materials guarantee low energy consumption and high heating rates due to their low thermal conductivity. The insulation and molybdenum disilicide (MoSi2) heating elements are installed in the rectangular housing. The heating elements are vertically hanging and can be replaced easily. At higher temperatures and in the presence of oxygen, MoSi2develops an oxide (SiO2) layer, which protects the heating elements against further thermal or chemical corrosion.

Three-zone tube furnaces (HTRH-3) can achieve better temperature uniformity than single-zone versions. In these models each zone is equipped with a dedicated thermocouple and controller, which is especially useful to preheat gases required for reactions inside the system.

The HTRH tube furnaces do not include an integral work tube. The work tube must be selected as an additional item. The work tube length is dependent on the application and will vary if used with or without modified atmosphere or vacuum.
