Standard Features:

Heavy duty, 4-cycle, direct injection, turbocharged
diesel engine provides maximum reliability.
Brushless alternator reduces service and maintenance
requirements and meets temperature rise standards for
Class F insulation systems.
Open delta alternator design provides virtually unlimited
excitation for maximum motor starting capability.
Automatic voltage regulator (AVR) provides precise
regulation.
Electronic Governor Control (Crystal Sync) — maintains
frequency to within ±0.25% from no load to full load.
Full load acceptance of standby nameplate rating in one
step (NFPA 110, para 5-13.2.6).
Sound attenuated, weather resistant, steel housing
provides ultra-silent operation at 63 dB(A) at 23 feet. Fully
lockable enclosure allows safe unattended operation.
Integrated fuel tank with direct reading fuel gauges are
standard.
Fuel/water separator removes condensation from fuel
for extended engine life.
Seven-stage powder coat paint provides durability and
weather protection.
WhisperWatt™ 85
Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge, fuel level
gauge, tachometer/hour meter, preheat indicator, and
emergency shutdown monitors.
Simultaneous single and three phase power.
Complete generator analog instrumentation includes
voltage regulator control, ammeter phase selector switch,
voltmeter phase selector switch, AC voltmeter, AC ammeter,
frequency meter, panel light, and circuit breaker.
Automatic safety shutdown system monitors the water
temperature, engine oil pressure, overspeed and overcrank.
Warning lights indicate abnormal conditions.
Automatic start/stop control — automatically starts the
generator set during a commercial power failure when used
in conjunction with a transfer switch.
Complete power panel. Fully covered; three-phase
terminals and single phase receptacles allow fast and
convenient hookup for most applications including temporary
power boxes, tools and lighting equipment. All are NEMA
standard.
Voltage selector switch allows easy to change voltages as
your applications require.
EPA emissions certified - Tier 3 emissions compliant.

Optional Generator Features:

Battery Charger — provides fully automatic and selfadjusting
charging to the generator's battery system.
Jacket Water Heater — for easy starting in cold weather
climates.
Special Batteries — long life batteries provide extra engine
cranking power.
Low Coolant Level Shutdown — provides protection
from critically low coolant levels. Includes control panel
warning light.
Spring Isolaters — provides extra vibration protection for
standby applications.
Trailer Mounted Package — meets National Highway
Traffic Safety Administration (NHTSA) regulations. Trailer is
equipped with electronic or surge brakes with double or triple
axle confi guration.

Optional Control Features:

Emergency Stop Switch.
Audible Alarm — alerts operator of abnormal conditions.

Ultra-Silent Features:

Low Noise Muffler — Large capacity low noise muffl er
minimizes exhaust sound.
Soundproof Casing — The new design divides the cabinet into
three sections, separating the engine, muffl er and radiator for more
effi cient cooling and reduces noise from the engine and fans.
New Cooling System — An advanced design uses two
separate air intake systems to cool the generator. The engine
fan draws air in to cool the engine and generator housing while
a second electric fan directly cools the radiator. With less air
being drawn into the generator through each fan, considerably
less noise is produced through the top of the generator.
Environmental Design — Constructed using an integrated
environmental skid and fuel tank. This design fully contains fuel
leakage and any liquid that might leak from the engine such as
lube oil or radiator coolant. All potentially hazardous liquids are
contained without contaminating the surrounding area.
