Atlas Copco Unveils Tier 4 Final QAS 25 Generator

Updated Oct 13, 2014

Atlas Copco Qas252Atlas Copco Portable Energy has released its QAS 25 generator, which is equipped with an Isuzu 4LE engine and a diesel oxidation catalyst to meet Tier 4 Final emission standards.

The QAS 25 is mounted on a frame and surrounded by an enclosure formed from galvanneal steel and is powder coated.

The generator is equipped with a Leroy Somer AREP alternator, as well as DeepSea 4510 controls.

Additionally, the unit comes standard with two-wire remote start capability and features a 72-gallon fuel tank for a 45-hour run time.

The QAS 25 enclosure features a vertical radiator and exhaust discharge to ensure low dBA levels for use on noise-sensitive jobsites.

Its voltage selector switch allows operators to adjust the machine’s output to 480 and 208/240 volt 3-phase settings as well as 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.

All maintenance points are on the side of the machine, and 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 machines fluids and fuel.

The QAS 25 comes equipped with an optional trailer with robust tie-downs for transport on a flatbed. Skid units contain fork pockets for forklift transfer. All units come with a standard single-point lifting eye in the enclosure for maneuvering with a crane.
