Cast copper electric heaters are suitable for high-temperature heating. This product utilizes tubular electric heating elements as the heating source, which are bent and shaped, then molded into various forms through centrifugal casting, including round, flat, right-angle, air-cooled, water-cooled, and other non-standard shapes. After precision processing, it can be tightly fitted to the heated object, with surface loading that can reach5-8w/cm²。
