Diesel Generators
Reliable Power, Built to Endure
Diesel Generators from OZWIDE are engineered for long-lasting performance, exceptional fuel efficiency and uncompromising reliability – trusted across commercial, industrial and residential applications. Designed in Italy, the Pramac-built diesel range combines advanced engineering with heavy-duty construction to deliver stable power in demanding environments.
Whether you need robust backup for your business, continuous energy for critical operations, or a dependable solution for a remote site, these generators provide the strength and endurance to keep you running. The lineup covers compact standby units through to high-capacity industrial sets, with superior fuel economy, low maintenance requirements and excellent load-handling capability.
The range runs from a 5.9 kVA single-phase set up to 1,409 kVA. Standby (ESP) is the rating for backup duty on a mains-connected site; prime (PRP) is the rating for continuous running where the generator is the only supply. Size to prime if the set is your main power.
Compact and Single Phase
Portable and small standby sets for homes, workshops, farms and light commercial use. Everything to 25 kVA, in single and three phase.
