Urea Tank Funnel

AGX Engineering designed a custom 316L stainless steel funnel assembly for a Perth-based transport fleet operator experiencing persistent DEF (Diesel Exhaust Fluid / AdBlue) spills during bulk tanker filling operations. The spills were causing corrosion damage to depot infrastructure and creating an ongoing environmental concern for the operator.

The assembly was designed to integrate with the client's existing Camlock tanker hose fittings and vehicle tank fill points, eliminate drip-back leakage after disconnection, and incorporate filtration to prevent particulate contamination of vehicle SCR systems. Internal flow path geometry was optimised through iterative CAD review to confirm acceptable flow characteristics at the required delivery rate.

AGX Engineering designed a 316L stainless steel fabricated funnel body with a 150 mm wide inlet aperture, a tapered internal geometry for flow continuity, and a 50 mm female Camlock outlet fitting. An integral 50-mesh 316 stainless strainer basket was detailed as a removable insert to trap particulate without requiring tool access for cleaning.

A spring-loaded non-drip ball valve was integrated immediately upstream of the outlet Camlock fitting to prevent post-fill backflow. All sealing surfaces and gaskets were specified in EPDM, which is rated for long-term chemical compatibility with aqueous urea solutions. The fabrication drawing package included cross-section drawings, weld details, a material compatibility specification, and an assembly and installation guide.
