Urea dispensers are equipped with automatic shutoff nozzles that stop flow when the vehicle’s DEF tank reaches capacity. This minimizes spills and prevents overfilling, which can cause crystallization or corrosion.
Electronic controls monitor flow rate and pressure during dispensing. If abnormal conditions are detected, the system immediately stops dispensing and alerts the operator.
Spill prevention protects the environment, keeps fueling areas clean, and reduces maintenance costs. It also improves safety and user experience at both public stations and fleet facilities.
