Atlas Copco QES Versatile Generators

The Atlas Copco QES versatile generators are designed to meet the demands of construction sites, emergency power needs, and outdoor events. Built with a robust structure, they are easy to transport and quick to install, ensuring reliable performance even in the harshest environments. The QES series offers excellent fuel efficiency and low-noise operation, equipped with advanced control systems for easy operation and simple maintenance. Whether for temporary power supply or continuous operation, QES generators deliver dependable and powerful energy solutions.

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 Atlas Copco QES Versatile Generators 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.

With exceptional reliability, we offer the most versatile solution in the market, with the lighter and most compact design. These generators, which make transportation and installation easy, are suitable for a broad variety of appliances with low to medium power requirements.While delivering excellent power quality,  Atlas Copco QES Versatile Generators super compact models bring significant savings
and business advantages.

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.

Optimize your power solutions

When you need temporary power, a single generator is not always the most efficient solution. Does the application load vary? Do any of the gensets in your fleet need higher power? A Modular Power Plant (or paralleling multiple generators) is the efficient solution if you answered yes to any of the these questions.

We have developed a unique Power Management System (PMS). The PMS manages the number of generators running in parallel with load demand, starting and stopping units in line with increases or decreases in load. In this way, the load on each generator remains at a level that optimizes fuel consumption.

It also eliminates the need for generators to run with low load levels, which can cause engine damage and shorten the life expectancy of the equipment.

Just one example:

The deployment of a 1MVA generator as a prime power source, taking the load demand patterns of a typical industrial application as a guide, could mean up to 1677 liters of fuel consumed each day. That compares with approximately 1558 liters of fuel if three QES 380 in the PMS were doing the same job. In this case, even considering the Ad-Blue cost, an estimated annual saving of more than €30.000 makes for a compelling case, not to mention 85 tons of CO2 saved over the course of a year.
