Yield the highest possible watt density for those applications that require intense heat in a relatively small package. They have the virtue of parallel power leads feeding one end of the element, rather than a circuit requiring configuration for access to both ends. BENCHMARK THERMAL'S Cartridge Heaters are manufactured of the highest quality nickel-chromium resistance wire wound on high purity magnesium oxide cores. These fully wedged heaters are designed for industrial use.
