Engine Heater SafeStart 100 series

DEFA has focused on easy installation and optimal heating functionality during the development of engine preheaters. For different engine and vehicle combinations, DEFA has nine primary heater elements with more than 500 variants and over 5000 individual applications.

These heaters have a flange shaped like a cup so that the active element fits within the cup. The heater is fastened with a press fit. This heater is used with engines that have coolant tanks that are too small for other heaters. It can only be installed in vehicles with cast iron engine blocks. The heater is available with conical surfaces in different diameters, making it possible to use it for different types of engines.

Engine pre-heaters are supplied separately because of specific necessary adaptations to each individual engine and vehicle type.
