Progressing in power from the 11 kW model, the liquid-cooled line of
QuietSource generators make available environmentally quiet operation while
resisting corrosion. Combining an air-channeling designed enclosure with
sound-deadening materials make these some of the quietest liquid-cooled
standby generators on the market. And because of the all aluminum enclosure,
these units are also corrosion resistant to keep up their good looks over
the long haul. Units run on either natural gas or LP gas.
Standard Features
- Built-in charger maintains battery at optimum performance level.
- Automatic safety shutdowns protect engine and generator in event of low oil pressure, low oil level, low coolant level, high temperature, overspeed and/or overcrank.
- Automatic seven-day exerciser runs the system for fifteen minutes each week to maintain top running condition.
- Transfer switch options are available in 200 amp size
Sound Attenuated Enclosure
- Engineered air-channeling and sound reduction design
- Sound-deadening material
- All aluminum
- Corrosion resistant

GENERATOR FEATURES
ˆFour pole, revolving field generator, directly connected to the engine shaft through a heavy-duty, flexible disc for permanent alignment.
ˆGenerator meets temperature rise standards for class “F” insulation as defined by NEMA MG1-22.4 and NEMA MG 1-1.65.
ˆRotor and stator and other insulation is impregnated twice with class “H” varnish.
ˆUnit tested for motor starting ability by measuring instantaneous voltage dip with an oscillograph.
ˆAll models utilize an advanced wire harness design for reliable interconnection within the circuitry.
ˆMagnetic circuit, including amortisseur windings, tooth and skewed stator design, provides a minimal level of waveform distortion and an electromagnetic interference level which meets accepted requirements for standard AM radio, TV, and marine radio telephone applications.
ˆVoltage waveform deviation, total harmonic content of the AC waveform, and balanced T.I.F. (Telephone Influence Factor) have been evaluated to acceptable standards in accordance with NEMA MG1-22.
ˆAlternator is of drip-proof guarded construction.
ˆFully life-tested protective systems, including “field circuit and thermal overload protection” and standard main line circuit breakers capable of handling full output capacity.
ˆSystem torsional acceptability confirmed during prototype testing.
Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with BS5514, ISO3046 and DIN6271). Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc.
