1 Atlas Copco Generators QAS kva / kw 60 Hz-Prime Power For your peace of mind.

2 QAS generators: the obvious choice Super-silenced canopy QAS generators are quiet. The use of foam lined canopies and advanced engines designed with many noise reducing features help to achieve low noise levels. QAS generators are suitable for use at night and in noise sensitive locations such as residential areas Sturdy and weatherproof The generator canopy is extremely robust. As it is directly mounted on a skid base 13 a QAS generator can be installed on any firm and flat surface and doesn t need any special foundations. The skid base of all QAS generators is sealed for 110% fluid containment. This feature prevents fuel, oil or coolant from causing any contamination, making QAS generators the environmentally-friendly choice. All major components 10 have flexible isolators to keep transmitted vibration to the absolute minimum. QAS generators are designed to withstand rough on-site handling and are suitable for use in demanding environments. The canopy is zinc-treated, with a powder coat paint finish for durability and excellent resistance to corrosion. Atlas Copco equipment keeps the integrity of its looks longer to help retain high residual values. Dependable diesel power 2 QAS generators are available with Yanmar, John Deere or Volvo diesel engines. These proven power units offer excellent fuel economy and unmatched reliability, even under the most severe conditions. All these engines are backed by an expansive nationwide support network and are protected by a comprehensive warranty. For trouble-free operation, all power units are fitted with a high capacity fuel filter/water separator. 14 This protects the fuel-filter injection system from solid and liquid impurities. A two-stage air filter, 3 with an inner safety cartridge protects the engine from dust and solid particles, regardless of the operating environment. Reliable alternator 9 The alternators used in QAS generators are designed and manufactured exclusively to Atlas Copco specifications and feature trickle dip winding impregnation. This stateof-the-art process offers the very best protection for the windings and will ensure maximum reliability and a long lifetime All three-phase alternators are equipped with a lockable voltage selector switch allowing the operator to easily configure the QAS to the voltage requirements of the application. The brushless excitation system and three phase sensing automatic voltage regulator (AVR) ensure rapid response to load changes and excellent motor starting capability. Continuous value Atlas Copco s experience in supporting rental customers around the world has lead to our focus on cost of ownership. QAS generators are designed with features which reduce the costs of service and maintenance. Extended service intervals and easy access to service points will keep downtime to a minimum and ensure lower operating costs. Continuous operation QAS units are designed to provide continuous prime power output 24 / 7 / 365. Skid-mounted QAS units are capable of full-shift operation without refueling. Trailer mounted QAS units include an auxiliary fuel cell that extends the fuel autonomy to 24 hours. QAS 325 QAS 3Ø-138

3 Monitoring at a glance The lighted, easy-to-read control panel is protected against unauthorized access by a lockable door, and allows for monitoring of all key operating functions without opening the enclosure. QAS units feature a comprehensive array of gauges including oil pressure, coolant temperature, fuel level, running hours, engine speed / frequency, and output voltage. 4 Individual ammeters monitor the amperage output on each phase, allowing the operator to easily identify load imbalances. Standard QAS units are equipped with an easy-to-use engine controller featuring local and remote start/stop control capability. The controller has LED shutdown indicators for system faults including high coolant temperature, low coolant level, low oil pressure, over-speed, over-crank, and under-voltage plus a warning indication for charging system failure. 5 Handling made easy QAS generators come standard with features which make transport and handling easy. The skid base includes forklift slots that can be accessed from either side of the generator and tie down points for secure transport. 11 In addition, QAS units are well balanced and can safely be lifted by a crane utilizing the integrated lifting beam. All QAS generators can be equipped with a heavy duty trailer for on-road transport. These rugged trailers are designed for easy mobility over the rough terrain encountered at the jobsite while maintaining the stability required for towing at highway speeds. The trailers can be specified with hydraulic surge or electric brakes to suit legal requirements and include DOT-approved lighting, reflectors and safety chains. Designed for safety QAS units are equipped with three pole main circuit breakers 6 for high or low voltage operation offering protection against overload and short circuit. The design of the terminal board allows quick fix electrical connections 7 while protecting against the risk of accidental contact with the terminal board. The emergency stop button 8 is recessed to prevent damage, but can quickly be accessed without opening the enclosure. Activating the emergency stop immediately stops the engine and trips the main circuit breaker. Power sockets, door handles and the fuel filler 15 are recessed to prevent damage and injuries to the operator. In addition the enclosure doors are lockable to prevent unauthorized access.
