Its construction features a helically wound resistance coil made from nickel-chrome wire, meticulously structured within a robust ceramic body. This design ensures maximum heat transfer and even distribution across the entire surface area of the heater. The nickel-chrome wire not only offers exceptional thermal conductivity but also exhibits high corrosion resistance, making it suitable for challenging environments. These heaters transmit heat through both conduction & radiation. The element winding is designed to heat the ceramic blocks to the point at which they radiate energy into the barrel as well as conduct energy by being in contact with the barrel – fit is not as critical as in other types of bands.
