Three types of fluid heaters made by Littelfuse perform essential functions in generators and vehicles that burn diesel fuel. Our diesel fuel heaters help keep fuel filters clear by preventing paraffin from dropping out of suspension. We also produce heater modules that combine fuel heaters with water-in-fuel detection and temperature sensors. Last, our DEF heaters stop diesel exhaust fluid from crystalizing into ice particles that could block fuel intakes or reduce the efficiency of selective catalytic reduction (SCR) systems.
