Products and positioning
Turnkey DEF and fuel additive dispensing solutions for fuel retailers, with no capital investment required from the retailer.
DEF dispensers
Additech installs, services, and manages DEF dispensers for convenience stores and truck stops. The dispensers allow diesel drivers to pump DEF by the gallon directly at the station without stocking bulky jugs or heavy constructions. They offer on-island and off-island solutions, fleet card acceptance, and no capital investment required.
Fuel additive dispensers

HUDD
Built for diesel-focused lanes and higher-volume fueling environments. Adds DEF sales without modifying the fuel island. Includes integrated card payment and receipt system. Available Cold Weather Kit options for reliable operations down to -40°F.
SUNLITE
UL-approved for safe installation directly on the fuel island. Lets diesel drivers fuel and refill DEF in one stop. Two displays allow for filling on either lane.
