A standby generator is an essential part of any company’s performance network. It needs to be ready and able to provide power in the event of an electrical supply interruption.

You need to be sure that the generator will sense the urgent need and provide an instant response, with guaranteed performance, at exactly the moment it’s needed.

We have extended our QES range with the new models up to 1250 kVA PRP to ensure we offer the generator that’s right for your business. Built to our time-tested design principles, used across our entire generator portfolio, the QES range offers you modular capabilities and room for upgrading and expansion; along with being designed for simple installation and exceptional reliability.

A Super Compact Solution

Super quiet, compact, and lightweight, not the usual adjectives that you would choose for conventional generators. However, the new super compact models are lighter and smaller than ever, and they still ensure power efficiency without compromising performance. In addition to their smaller dimensions, the new models offer reliable power thanks to their state-of-the-art Automatic Voltage Regulator (AVR) and engine speed control.

Atlas Copco QES super compact

QES super compact

The innovative super compact QES model is designed to grant the most efficient transportation. You can fit up to 30 units of Atlas Copco QES 20 in a 40 feet container, the most for a 20kVA power generator in the market! It means optimized transport, reduced CO2 emissions and operational costs, which results in a lower Total Cost of Ownership (TCO). Its environmentally friendly design makes it ideal for storage overseas, reducing exponentially your footprint on-site.
