QAS125JD

The Atlas Copco QAS 125 JD T4F generators are prime power, multi-voltage, sound attenuated, mobile generators. They are powered by a John Deere T4 Final liquid-cooled, six-cylinder diesel engine.

The units consist of an alternator, diesel engine, cooling system, electrical distribution and control systems - all enclosed within a sound attenuated enclosure fabricated from powder coated steel with zinc rich primer. 1000 hr salt spray teste. A broad range of undercarriage formats and options are available. Special attention has been given to the overall product quality, user friendliness, ease of serviceability, and economical operation to ensure best in class total cost of ownership.

All QAS generators include the latest Tier 4 Final engine and have a footprint that is up to 20 percent smaller than the previous generation. The starting mechanism ensures that stable power is achieved in less than six seconds.

Construction

Construction site with QAS 40 and XAS 97

Generators can supply power to temporary structures and construction equipment that require electricity to operate. The QAS 125 Portable Generator is suitable for less complex projects such as small road construction, single family houses, and low-rise apartments.

Events

Construction site with QAS 40 and XAS 97

Outdoor events such as festivals, sporting events, and the like depend on high-performing generators to keep the function running smoothly. Easy-to-use interface and water-resistant design ensure inclement weather or poor handling will not impede the event.

Utilities

Construction site with QAS 40 and XAS 97

Natural disasters and inclement weather are the main causes of power outages. Protect yourself against an outage with our QAS 125 Generator. With an intuitive system controller, you have advanced warning and alert parameters for added safety.
