SSI is an industry leader in the design and manufacture of DEF/Urea sensing solutions and DEF/Urea delivery modules for automotive, on-highway truck and off-highway applications.

  • SSI provides a fully integrated Tank Systems (with and without heater tube assemblies).
  • Stainless Steel pick up and return lines and engine coolant loops.
  • Multiple header designs available and engine coolant loops specifically designed and certified to your tank’s configuration.
  • Top mounted with standard and custom header configurations.

    Modular design is very flexible allowing customization to various tank heights, cable harness and connector needs.


    Critical features include:

    SSI has developed a filter designed to eliminate the effects of aerated DEF on sensor performance.

    Design considerations include:

    • Packaging - Minimal effect on required sensor packaging space
    • DEF compatibility - EPDM filter material compatible with DEF
    • Concentration-response time - Minimize effect on concentration-response time
    • Level response time - Minimize effect on level response time
    • Robustness - Must meet all durability test requirements
    • Thaw performance fully qualified to meet EPA requirements
    • Extensive durability testing (freeze, vibration, etc.)
    • “Off the shelf” solution requiring no customer-owned tooling
    • Five different tank volumes (5, 10, 15, 30 gallons)
    • Tanks available in both portrait and landscaped shapes to allow for easy vehicle integration
    • Lockable Cap option
    • Fill nozzle filter
