Engineered fuel infrastructure. Personally accountable.

D&O Technologies is a U.S.-based company specializing in engineered fuel infrastructure for commercial and defense applications. We design, build, and deliver fuel storage, transport, and dispensing systems engineered for demanding environments across the Americas, Europe, and beyond.

Our fuel systems are supported by our long-standing manufacturing partnership with an established European manufacturer with decades of experience in fuel storage, transport, and dispensing equipment deployed in more than 100 countries.

Every project is backed by leadership that remains personally engaged from proposal through delivery, ensuring accountability, responsiveness, and execution. As an independently owned company, we have built our reputation on long-term relationships, technical expertise, and direct owner involvement in every program we deliver.

From our headquarters in Miami, Florida, we deliver engineered fuel systems and, in partnership with QPR, a QUIKRETE® Companies brand, permanent cold mix asphalt to customers across the United States, the Caribbean, Latin America, and Europe.
