Agricultural machinery operates under extreme conditions: dust, dirt, temperature fluctuations, long downtimes between seasons, and varying fuel qualities are part of everyday life in the field and in the machine park. This combination makes fuel contamination one of the most common and costly problems for farm managers and farmers.

Water in the fuel system is one of the most common and, at the same time, most difficult to diagnose causes of engine damage in maritime operations. Whether through condensation in tank ventilation systems, leaking tank caps, fuel deliveries with increased water content, or the hygroscopic properties of modern biofuel components: water enters the fuel tank in many ways—and from there, the entire injection system.
