Kanthal is the brand for Sandvik’s heating technology products and services. The Kanthal brand belongs to the Sandvik Group, a high-technology engineering group with expertise in areas such as industrial heating and materials technology.
High-power electric molybdenum disilicide (MoSi2) heating elements for element temperatures up to 1850°C (3360°F). Kanthal Super MoSi2 heating elements are available as straight or bent elements in a wide range of shapes and sizes, all characterized by long life and consistent performance.
The Kanthal program of MoSi2 heating elements includes seven grades with specific features for use in demanding applications and atmospheres, including nitrogen, hydrogen, vacuum and mixtures of endogas and reducing atmospheres.
In addition to MoSi2 elements in standard shapes and sizes we provide special designed MoSi2 elements according to customer needs, enabling an optimized element design for each particular application.
Silicon carbide (SiC) electric heating elements for element temperatures up to 1625°C (2927°F), available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment.
Kanthal Globar SiC heating elements are capable of high power output, and may be mounted either vertically or horizontally. Because the element material remains rigid even at the maximum operating temperatures, no special supports are required, which simplifies the design of the equipment.
The Kanthal program includes several types of silicon carbide (SiC) heating elements for float baths used in the manufacture of soda-lime flat glass for architectural, automotive and solar-glass applications. Special float elements for flat panel display glass are also supplied.
Kanthal and Alkrothal FeCrAl alloys are characterized by high resistivity and capability to withstand high surface load. They can be used at maximum element temperature of 1425°C (2600°F).
The NiCr-based alloys are characterized by very good mechanical properties in the hot state as well as good oxidation and corrosion properties. They are suitable for element temperatures up to 1250°C (2282°F).
Using Kanthal FeCrAl alloys instead of NiCr alloys results in both weight-saving and longer element life, leading to considerable cost savings.
Prefabricated heating modules consisting of vacuum-formed ceramic fibre with an integral Kanthal Super molybdenum disilicide (MoSi2) heating element for up to 1750°C (3180°F) element temperature.
Superthal heating modules are intended for use in laboratory or production furnaces/heaters wherever concentrated heat is needed. They also provide major energy savings in several applications. The flexibility of the heating modules allows for different tests and processes to take place in the same furnace set-up.
Prefabricated heating modules with metallic heating elements and vacuum-formed ceramic fiber insulation for up to 1350°C (2460°F) element temperature.
The construction method of Fibrothal heating modules ensures accurate positioning of the coils and eliminates the distortion or other problems connected to the conventional open coil elements in grooves or on tubes. Fibrothal heating modules also provide major energy savings in several applications.
Prefabricated heating modules with metallic heating elements and non-electrically conductive, dense ceramic insulation for use at element temperatures up to 1350°C (2460°F).
The construction method of Moduthal heating modules ensures accurate positioning of the coils and eliminates the distortion or other problems connected to the conventional open coil elements in grooves or on tubes.
A fibre-free version of Moduthal heating modules is available for up to 1250°C (2280°F) element temperature.
