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.
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.
