Self-regulating tube glow plugs with short heating period. Twin-spiral design.

Modern glow plugs with very short build-up to operating temperature. By using the most suitable heating materials and regulating heating coils, it is possible to achieve the optimal temperature of the active parts of the glow plugs in all engine operating modes with a very long replacement interval.

The heating coils of these heaters are made from resistive wire or strip and are used for preheating the intake air to ease diesel engine start.

Coil from resistive material, low-pressure design.

Coil from resistive material. For older design of diesel engines. Glow plugs without regulation. Used in a series connection circuit, mostly with heating indicator light from the same resistive wire as the heating coil
