Atlas Copco has announced a new addition to its QAC range of containerised generators, the QAC 1450 TwinPower. It is a 20 ft. ISO containerised unit housing two compact 725 kVA generators; powered by V8 Scania engines with double bearing alternators. This configuration, with its fast-paralleling system, allows the two generators to work independently or in parallel with each other. The system is fully EU compliant. 

“From full load to low load, our TwinPower concept provides the same output, performance and efficiency as a single generator package, thereby achieving up to 10% in fuel savings,” said Sergio Salvador, product marketing manager for Atlas Copco's Power and Flow division. “In essence, two generators, which are powered by smaller engines, behave as one large one; while providing far more flexibility and contributing to a lower overall cost of ownership.”

Atlas Copco’s TwinPower operating principle is based around the concept of two generators, with two independent engines, inside one box. The QAC 1450 is the latest model to be launched.

The QAC 1450 is equipped with a centralised control and monitoring system. It can be configured and used through two Qc4003 digital controllers with touchscreens, and a choice of island or PMS (Power Management System) modes. The QAC 1450 can either run as a standalone unit, in parallel with other generators, or in parallel with mains power.

Capable of operating continuously in challenging conditions, including high altitude environments, the containerised TwinPower generator system has an intelligent cooling system that ensures optimised performance at temperatures up to 50 °C.

It has large access doors and custom service tools helping to maximise uptime. It requires less than two hours of maintenance for every 500 hours of operation. Because of the twin power concept, it is possible to still benefit from 50% of the unit’s total capacity during maintenance operations.

It is manufactured to perform under demanding conditions including those common to oil and gas operations, the QAC1450 meets ISO8528 specifications, and is compliant with all current EU safety and environmental regulations.
