Milton CAT D7E Tier 4 Interim-Stage IIIB - Manual (Page 4)

Cooling System
Efficient
and
easy
to
service
The
D7E
cooling
system
uses
a
three-part
radiator
built
with
rugged,
highly
efficient
aluminum
bar
cores
for
charged
air,
jacket
water,
and
the
separate
circuit.
Although
the
jacket
water
and
separate
circuit
coolant
operate
at
different
temperatures,
the
radiator
appears
and
acts
as
one
integrated
unit.
Airflow
is
managed
by
a
hydraulic
variable
speed
demand
fan,
reducing
power
requirements
and
fuel
consumption.
A
molded
shroud
ensures
efficient
air
flow
through
the
radiator
and
the
fan
utilizes
lightweight,
durable
blades
for
high
effi
ciency
and
quiet
operation.
A
larger
gap
between
fi
ns
reduces
plugging,
and
the
single-plane
design
allows
for
easier
cleaning
and
service.
Engine
ACERT ™
Technology
The
D7E
features
a
Cat
C9.3
ACERT
engine
and
a
Cat Clean
Emissions
Module
aftertreatment
to
deliver
the performance
and
efficiency
that
customers
demand,
while meeting
U.S.
EPA
Tier
4
Interim/EU
Stage
IIIB
emissions
standards.
The
efficient
drivetrain
allows
the
engine
to
operate
in
a
tighter
rpm
range,
1,500
–
1,800
rpm,
which
helps
extend
engine
life
and
improve
fuel
economy.
The
increased
drivetrain
efficiency
also
allows
the
machine
to
achieve
greater
performance
at
lower
horsepower
than
previous
models,
adding
even
more
to
the
D7E
overall
benefi
ts.
Features
•
Serviceability:
Electric
priming
pump
and
easier
engine
access
make
service
easier.
•
Leak
Protection:
Components
are
sealed,
preventing
leaks
and
protecting
fluids
from
contamination.
