Product info & Technical Data:
TYPE D
The D element is made from high-density, high-purity silicon carbide. Using the most modern production technology and expertise developed by TKK from past experience, Type D features high oxidation resistance, heat resistance and reinforced strength. Type D is the most popular type of economical heating element capable of operating under hot and rigorous environments. As required by specific applications, various coatings can be applied to D-type elements to prevent oxidation.
TYPE E&F
These are improved versions of the D-type. Modifications have been made to reduce the cold-end terminal resistance and heat loss. When used in general-purpose industrial furnaces, they can reduce energy consumption by as much as 5% to 10% compared with the D-type.
TYPE U
Two E-types are constructed to from a U-shape. Consequently Type U have the terminals at one end (similar to Type SGR) for a single-phase power source. This reduces the number terminations and cold ends thus enabling energy savings.
TYPE W
Three-legged W-type elements, with the terminals at one end, are designed for three-phase power source applications, such as the float glass process.
TYPE SG
SG-type elements, with a spiral-grooved heating section, are more resistant to heat and corrosion than conventional products and are able to withstand operation in rigorous conditions. The interior of elements with large diameters can be used as a tube furnace. As in Type E, SG elements are provided with energy-saving, low-resistance, cold-end terminals.
TYPE SGR
SGR Type elements are made from very dense silicon carbide, featuring a return spiral groove allowing connection at one end. The resistance and allowable surface loadings of the SGR Type are substantially higher than other silicon carbide elements, consequently operating voltages are higher and current draw lower. This feature can lead to significant savings in both control equipment and wiring. SGR elements are energy conserving, convenient and easy to install due to the same-end terminal structure.
INTERCHANGEABILITY
Premier grade high performance silicon carbide heating elements, we are the only high quality manufacture in China.
Elemens can also be tailored in special sizes and resistance values to replace elements supplied by other providers in Asia and European. It is important to provide the norminal electrical resistance when ordering sic heater.
