Part name: Diesel Heater with Integrated Sensors
Eltek diesel heaters are designed to keep engines ready for instant cold weather operation. Fuel heaters are also vital for biodiesel applications. Fuel heaters dissolve paraffin wax crystals and ice. Heaters enable water separators to work more efficiently and prevent fuel filter plugging from wax or ice. According to Eltek experience in automotive sensors production, diesel heater can be integrated with water detection (WIF) sensor, temperature detection, pressure detection (used to detect filter block or to control variable speed of fuel pump). Dimensions are tailor-made according to customer requirements. Electronic switch available; version with microcontroller available (heating ON/OFF decided by Eltek software).
