Heating coils and meanders

Broad range of types, sizes and temperatures


Elektrotermija produces open coils, spirals and meanders in a broad range, according to customer specifications. Wires, rods, ribbons, strips and tapes can be straight or bent in a wide range of shapes and dimensions. Coils and meanders are usually supported by ceramic bodies and bearers. Power and voltage are determined according to requirements. Maximum allowed temperature is up to 1400°C, depending on the heating alloy. These types of elements are mainly used for industrial ovens, convectors, packaging industry, dryers, etc.
