Rugged and Reliable Design

The WhisperWatt generator features heavy-duty steel enclosures and vibration-isolated components. It withstands harsh weather and extended operation, so it remains dependable in remote or urban environments. With this durability, the 125-600kVA proves ideal for long-term projects.

Fuel Efficiency and Compliance

Equipped with fuel-efficient diesel engines, the series meets EPA Tier 4 Final standards. As a result, the 125-600kVA maximizes runtime while reducing emissions, which keeps your operation efficient and environmentally responsible.

Smarter Control and Monitoring

Digital controllers make operation straightforward. With real-time monitoring, auto-start features, and paralleling capabilities, managing power becomes easier and more efficient.

Applications That Rely on Quiet Strength

The Multiquip 125-600kVA WhisperWatt generator supports industries where quiet power remains essential. These silent generators provide energy for film production, outdoor events, hospitals, and emergency centers. They also play a key role in mining, utilities, and heavy construction.

When you need a whisper generator that balances massive capacity with low noise, the 125-600kVA series delivers. Strong, efficient, and durable, each WhisperWatt generator performs with confidence under pressure.
