Built in Wilmington, NC, the HERO Diesel combines marine-grade water-cooled technology with rugged diesel performance for unmatched durability in coastal and remote environments. Using a powerful V3300 engine, it cools both engine and exhaust through a water-loop system, eliminating corrosive salt air intake and allowing installation closer to structures without heat risk. Operating at just 1800 RPM in an insulated fiberglass enclosure, HERO runs quietly and efficiently. It's integrated diesel tank offers safer, longer-lasting fuel storage, and in emergencies, a quick‑connect design lets you swap units with minimal downtime. Perfect for homes, farms, or businesses needing robust backup power.

Compact, coastal‑tough, and quiet—the Mini‑HERO delivers 8.5 kW or 14 kW of reliable power in a water-cooled diesel package. Featuring a Lombardini or Kohler engine and enclosed in a sleek, insulated fiberglass housing, it avoids drawing corrosive air inside while staying whisper‑quiet. Ideal for tighter lot lines or residential use where footprint and space are critical, the Mini‑HERO still brings full HERO-level durability and peace of mind.

The RAD.CO is the radiator-cooled version of the HERO, available in both 14 kW (V1505 engine) and 30 kW (V3300 engine) models. It offers a more traditional cooling system while maintaining HERO’s enclosure design and coastal protection features. With its radiator cooling, RAD.CO is easier to integrate where a water-loop setup isn’t feasible, yet still resists salt-air corrosion and benefits from HERO’s low-noise, quick-connect architecture.
