Two generators housed in one container

Atlas Copco Power Technique’s QAC1100 TwinPower solution consists of two fully loaded generators housed inside a custom 20-foot container and is designed to provide a reliable and flexible prime and critical standby power solution.

“By containerising two QAC generators alongside each other, we have essentially packaged up to 1 MW of predictable power on a single platform, in effect doubling the power and flexibility for our customers and end-users. Adding even more value, this time from a productivity and uptime perspective, the QAC1100 TwinPower  is also a back-up solution as one generator can run at 50% while the other is being serviced, thus providing end-users with seamless 24/7 power supply,” states Atlas Copco Power Technique business line manager - portable products David Stanford.

The smart configuration of the solution features a fast-paralleling system, allowing the two generators to work independently or in parallel with each other, providing multiple solutions and combinations between prime and standby use, one unit working at 50 Hz and the other at 60 Hz. This enables customers to choose the most suitable power solution for specific applications.

A smart electric variable speed drive (VSD) motor-driven cooling fan adjusts the cooling flow to the specific requirements of the engine. The VSD-driven engine/alternator cooling system enables 100% power at 40 °C at an altitude of 1 000 m.

The engine/alternator performance, in association with its respective advanced control systems, can accept a 100% load step with more than 70% load step acceptance within the ISO 8528-G3 class respectively. The standard heavy-duty dual-stage fuel and air filtration contribute to longer up-time and extended service intervals.

The QAC generator is said to save up to 10% fuel at maximum performance. Improved fuel efficiency and a spillage free frame, which can contain 110% of the fuel tank capacity, helps to reduce the impact on the environment. A low noise level of 70 dB(A) at 7 m and an easy-to-use touch screen add to workspace safety and comfort.

With a compact footprint and equipped with solid lifting eyes and forklift inlets, the 20-foot ISO-certified container, housing the two QAC generators, is designed to be easily transported for optimum portability.  

The generators require less than two hours of service after 500 hours of operation and large access panels and custom service tools contribute to ease of maintenance. The two generators’ engines and alternators are positioned on opposite sides of the platform, to facilitate easy access to major components. A slide in/out base frame enables easier removal of the aggregate engine from the container for maintenance and other operational tasks.

This modular solution is unrivalled when it comes to flexibility and economy and will provide reliable power for virtually any application that has variable load requirements across a wide range of industries including utilities, construction, mining, quarrying, and oil and gas, not forgetting the rental sector,” adds Stanford.
