QAS 25

One of Atlas Copco’s latest additions to its generator lineup, the compact QAS 25, is equipped with an Isuzu 4LE engine and a diesel oxidation catalyst (DOC) to achieve Tier 4 Final emission levels.

The generator is ideal for heavy-duty use in several industries, including rental, oil and gas, and construction. It is also an exceptional option for powering events. It can be used for prime or standby power and is designed to withstand the rigor of demanding use in the field.

The generator’s overall durability, as well as the quality and dependability of its interior components, gives it a high resale value. For example, the generator is mounted on a durable frame and surrounded by a robust enclosure formed from galvanneal steel and powder coated for a long-lasting, scratch and corrosion resistant surface.

In terms of performance, the generator is equipped with a dependable Leroy-Somer AREP alternator for optimal motor-starting capability. Deep Sea 4510 controls are comfortable, reliable and easy to use. The unit comes standard with two-wire remote start capability and features a 72-gallon fuel tank for a 45-hour run time.

The unit’s versatility can be seen but not heard. The generator’s enclosure is sound attenuated, and it has a vertical radiator and exhaust discharge to ensure low dBA levels for use on noise-sensitive jobsites, residential areas or at events. Its voltage selector switch allows operators to adjust the machine’s output to the 480- and 208/240-volt three-phase settings, as well as the 120/240-volt single phase for varying applications and equipment.

For additional safety, the locking front panel voltage adjust potentiometer prevents unintentional adjustments to the voltage, which can cause overheating or equipment damage. The 120vac GFCI duplex receptacles are always powered, giving users the ability to operate small hand tools while running larger loads.

The company designed this generator for fast and easy maintenance with large doors and all maintenance points on one side of the machine. The DOC after-treatment device requires no regeneration or maintenance. The engine meets Tier 4 Final emissions without the need for diesel exhaust fluid or a diesel particulate filter system.

Further, engine fluids are plumbed to the edge of the skid to eliminate the hassle of maneuvering pans into the interior space. The standard spillage-free base frame safeguards the site and protects the environment. It’s sized to contain 110 percent of all the machine’s fluids and fuel, giving users confidence in the most environmentally sensitive areas.

All units come with a standard single-point lifting eye in the enclosure for maneuvering with a crane.  FG
