ZYLAB U Type Silicon Carbide Heating Element
Introduction
ZYLAB U Type Silicon Carbide Heating Element is a high-performance, double-leg SiC heater designed for use in high-temperature electric furnaces up to 1500°C.
With two heating legs connected by a non-heating cold end, this element is ideal for vertical or horizontal installation, offering uniform heating, long service life, and excellent oxidation resistance.
ZYLAB provides a wide range of standard sizes and supports custom fabrication based on your furnace design and process requirements.
