1 MW Generator in a Standard 20’ Container

Atlas Copco added the new QAC 1250, its first 1 MW generating unit, to the current QAC range in response to interest from the rental and power generation markets.

"This new model is the realization of the long held dream of our loyal QAC users. They've been asking for a 1 MW unit in the same box as the well-known and successful Atlas Copco QAC 1000 Model. We've developed this unit based on their input," says Júlio Tomé, product manager. "The footprint and dimensions are the same, but there's 25% more power in the box!"

Júlio Tomé explains why this unit is in such demand. "The standard model is fully equipped and comes with the most common features normally seen as options such as the Qc4002 controller for paralleling, dual frequency, coolant heater, battery charger, automatic fuel transfer system, air inlet shut down valve, spark arrestor, as well as heavy-duty protection for the engine, alternator and electrical system. Because of its versatility, it can be used on nearly any type of application, making it suitable for the rental industry. One common application is where it can be used as a temporary power supply to industrial plants, and the 1 MW is right in-line with the nominal power of transformers. It is also excellent for events, temporary power generation in remote locations, construction sites, mining, refineries, heavy-duty standby power and much more.”

The new QAC 1250 is a dual frequency unit delivering 1250 kVA / 1000 kW of prime power at 50 Hz and 1450 kVA / 1150 kW at 60 Hz. The unit is now ready for some of the toughest applications where efficient, quick and reliable power is required.

The engine choice for this new model is the KTA50 from Cummins, coupled with a Leroy Somer alternator. This setup, in addition to Atlas Copco's innovative QAC cooling concept; the unit has a variable speed electric fan in a dedicated coolant compartment – ensuring the best mixture of size, noise level and power performance on a portable / multi-drop unit, both at high altitudes and higher ambient temperatures.

Easily handled by crane, lift or truck, the robust 20’ CSC ISO container enclosure has lockable, wide opening doors so that all components are easily within reach. This helps to ensure that maintenance and service is both quick and stress-free.
