New generator platform
Providing 40 kVA and 60 kVA prime power,
respectively, the G40-IIIA and G60-IIIA
models are part of the new platform of
generators from Doosan and share a
common design with the G80-IIIA to G200-
IIIA models launched over the last two
years. The Yanmar-powered G40-IIIA and
John Deere-powered G60-IIIA generators
will both be available with electronic speed
regulation (optional on the G60-IIIA model)
providing, in addition to stability and better
load take-over capabilities, a flexible dual
frequency 50/60Hz working mode (optional
for both models).
New stage IIIA portable
compressor
The new 7/53 portable compressor is a
36 kW Stage IIIA compliant replacement
for the 7/51 model and has been redesigned
to allow Doosan to keep this model in the
Stage IIIA category, avoiding the need to
transition to meet Stage IIIB regulations.
The new features on the 7/53 portable
compressor include forklift slots and a new
bunded base option.
The 7/53 compressor has an intuitive,
simple key-start sequence, ideal for rental
companies because of the reduced risk of
machine abuse by untrained operators.
The user-friendly control panel offers
an open layout of instruments and warning
indicators. A folding lift bail reduces the risk
of theft by keeping the lifting eye within the
compressor enclosure. A built-in toolbox
compartment offers ample storage space.
New stage IV compliant
portable compressors
The largest single axle model from Doosan,
the new 12/154 compressor is the Stage IV
successor to the previous 12/150 model and
is again powered by the Cummins QSB6.7
6-cylinder diesel engine and meets Stage
IV regulations without the need for a diesel
particulate filter (DPF).
Compact in size, the 12/154 offers excel-
lent towing stability. It is intended for appli-
cations in plant hire, construction, quarrying
and general industry.
This encompasses not only standard
compressed air applications such as
powering breakers and tools in road
repair, demolition and refurbishment, but
also more specialist uses such as drilling,
NEW IN PARIS
The Doosan Portable Power display at the Intermat 2015
Exhibition will include a number of important new
products being launched at the show. They include
redesigned and Stage IIIA compliant G40-IIIA and
G60-IIIA generators, alongside several new
portable compressors including the Stage
IIIA compliant 7/53, Stage IV compliant
12/154 and 12/254 and 7/125-10/110
Stage IIIB Dual Mode models.
abrasive blasting, spray painting and optical
fibre blowing.
Also meeting Stage IV emission stand-
ards, the new 12/254 compressor is powered
by the 247 kW Cummins QSL9 diesel engine
meeting the regulations without the need
for a DPF. The 12/254 model again offers
both compact size and easy serviceability for
added value performance.
New ‘dual node’ feature
The 7/125-10/110 Stage IIIB model has a
new ‘Dual Mode’ feature as standard, with
a choice of two pressure and flow ratings
on the same machine. By pushing a button
on the keypad, the operator can switch
between ‘LO’ and ‘HI’. This ‘two-for-one’
solution replaces the need to choose
between different models as used to happen
in the past and offers much greater opera-
tional flexibility from the same machine.
The
new
7/125-10/110
portable
compressor is powered by the Stage IIIB
Cummins QSB 4.5 water-cooled diesel engine
providing 97 kW of power and meeting emis-
sion regulations through the use of cooled
exhaust gas recirculation (EGR) and diesel
oxidation catalyst (DOC) after-treatment
technologies, without the need for a DPF.
