PORTABLEPOWER
Set and forget
C
onstruction sites often rely on portable power options to
keep things going. From high capacity generators that
can producemultiple power to run site offices and large
equipment, toportable air compressors for hand tools andother
applications.
As technologyadvances,portablepowerproducts arebecoming
smaller in size but bigger in power, while emission regulations
meanunits are becoming cleaner too.
“Our innovations will continue to focus on optimal sizing,
meaning a smaller footprint and smaller units for the same job
as well as a strong focus on fuel consumption and alternative
fuel sources.We will also lookmore at specifics, such as voltage
variants and coldweather requirements,” explained JulioTome,
product marketing manager for on-site generators at Atlas
Copco.
Lean& green
AtlasCopcoPortableEnergy introduced its latest range ofTier 4
Final portable generators for heavy-duty applications atMarch’s
ConExpo exhibition in Las Vegas, US. The new QAS 25 and
QAS 50 60Hz generators use an Isuzu 4LE engine fitted with
just a diesel oxidation catalyst (DOC) for aftertreatment to
achieveTier 4Final emission levels.
The new QAS 25 and QAS 50 replace the existing QAS 25
and QAS 45 models to become the first
Tier 4Final generators fromAtlas Copco
since the emission standard took effect on
January 1, 2013. By the end of the year,
all other Atlas Copco portable generators
will beTier 4Final-compliant.
Both the QAS 25 and QAS 50 have a
silent enclosuredesign toensure lownoise
levels for use in residential or other noise-
sensitive locations. DeepSea controls and
a Leroy Somer AREP alternator ensure
easy operation of the generator in a range
of heavy-duty applications.
