Up to 20 MVA stable power

32 units of the QAS 625 can be linked together in paralleling for specialized applications, providing up to 20 MVA of stable and reliable power.

Double runtime

Up to 40-hour fuel tank capacity provides longer runtime between fill ups and optimum site autonomy.

Corrosion resistant canopy

1000 hour salt test

Stable power in less than 6 seconds

The starting mechanism ensures that stable power is achieved in less than six seconds.

Dirt and dust. No problem!

All QAS generators have dual stage filtration with a safety cartridge and dual stage air cleaning. This centrifugal dust separation system and heavy duty filtration system prolongs the life of your generator.

QAS generators

The ideal mobile diesel generator solution for rental companies

The QAS generator range was designed specifically for the needs of the US market. The range has been completely overhauled and incorporates nine models covering power rating from 25 to 625 kVA. All QAS generators include the latest Tier 4 Final engine and have a footprint that is up to 20 per cent smaller than the previous generation. The starting mechanism ensures that stable power is achieved in less than six seconds.

The range is all about the user experience and maintaining the value of your asset. It’s packed with features that make operating, transporting and maintenance as easy as possible.

What is more, up to 32 units of the QAS 625 can be linked together in paralleling for specialized applications, providing up to 20MVA of stable and reliable power.

Make the Perfect Power

When you need power, maybe a single generator is not always the most efficient solution. Does the application load vary? Do you need prime power for long term projects on a remote site? Do you need a semi-permanent installation that can be upgraded or downgraded?

A Modular Power Plant (or paralleling multiple generators) is the efficient solution if you answered yes to any of the above questions. Simply, this is a configuration of generators working together.

We have developed a unique Power Management System (PMS). The PMS system enables the optimization of fuel consumption and expands the generator’s lifetime. PMS manages the quantity 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 which 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.

Power Management System

The generators incorporate Atlas Copco’s Power Management System (PMS) that manages the quantity 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 which optimizes fuel consumption and eliminates the need to run with low load levels, which can cause engine damage and shorten the life expectancy of the equipment.

Designed to be moved around

Available in either a skid mount (except for QAS 95 and QAS125) or trailer mounted configuration, they are designed for safe and easy movement and adaptable to whatever the job site demands. Compact for better maneuverability, they offer efficient transportation with more units per truckload resulting in lower transportation and storage costs.

Anti-rust canopy

The units are fully protected by heavy duty, weatherproof, enclosures that feature an integrated door sealing system comprising a unique foam and seal layering structure to ensure water-tightness and improved sound attenuation. The QAS anti-rust canopy has a unique “no weld” corner design to eliminate traditional rusting spots. Furthermore, the spillage-free frame, which is standard across all models helps to minimize environmental impact.

All under control

Intuitive but simple controls, with easy to read display and customizable menus, put the operator in complete control of functions, QAS controllers feature the latest technology including advanced warning and alert parameters.

Overall, the new plug and play QAS generators offer a combination of reliable engine power, compact design, 500-hour minimum maintenance intervals, simple paralleling and long service life. Optimum fuel savings and better fleet utilization contribute to increased revenue for mobile site and industrial plant operators.
