Portable Generator QAS-250kW
General Information
The Atlas Copco QAS 250 JD T4F generators are prime power, multi-voltage, sound attenuated, mobile generators. They are powered by a JD 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.
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.
