Kubota Generator Sets
Recently, Kubota launched a new model of diesel engine generators chosen the SQ series, as super quiet. The SQ series covers both 60Hz and 50Hz outputs. The 50Hz generated have a high output range of 11 to 15kVA in 1 phase, and 14 to 30kVA in 3 phase models. The 60Hz generators have an output range of 13 to 20kVA in 1 phase and 17 to 35kVA in 3 phase models. This is the very first time that this manufacturer has given the market high quality generators with greater than 35kVA output.
Major design themes for the Super Quiet series generators are safety, low noise, easy maintenance, transportability, and etc., with the highest emphasis on less noise. Noise generated by the unit has been lessened to below 65 dB by enhancing the noise reduction cover and by adding new noise absorbing duct with 3 air intakes. Generators show either an over-sized muffler or a 2nd muffler, depending on the model of the engine. Kubota went to a
bigger-diameter as well, slower speed fan to lessen noise emissions. An air
cleaner inlet hose is another design feature to lessen low-frequency noise.
The main applications for the Super Quiet series generators
are general contractors and construction, municipalities, marine and
agriculture markets. The huge capacity bottom mounted fuel tanks add to
preventing fuel drops in the enclosure. A locking cap is recessed to prevent
from damage and simplify refueling.
The sophisticated design is planned to minimize both weight
and space. Transportability is developed by including slots on every side of
the generator for safe truck transportation. Sturdy lifting eyes and 4 tie-down
points further enhance transportation and hoisting.
Operating features are carefully planned as well. Each time
the engine is turned on, for instance, air is automatically cleansed from the
system. A locking-control panel-door shields the panel from the elements and
allows observation of all functions without the need to open the door. An
automatic-start system is showcased for stand-by applications, with space and
wiring provided. A voltage switch is given for rental industry usage and no
wiring is required.
Maintenance and safety issues were also significant
considerations. The SQ series show a complete covered load center that has all
the outlets, circuit breaker and compression terminals. To avoid unintentional
contact with the outlets, the receptacles are placed in separate sections. GFCI
receptacles are equipment to enhance safety. For safe operation, the
maintenance doors are packed with safety interlocks.
Large doors showcase heavy duty steel hinges and recessed
locking-door bolts safeguard against illegal use, allow safe, easy maintenance
and unattended operation. One side maintenance is also a design feature.
Coolant drain extensions and engine oil are given to ease regular maintenance.
Oil gauge, oil replacement port, oil filter, fuel filter, battery and air
cleaner, and water reserve tank are all situated on 1 side for quick
maintenance and inspection.
If unnecessary things occur with respect to water
temperature, oil pressure, or fan belt, the engine is turned off automatically.
And if the battery is worn out, the engine is shut down by the energized-stop
solenoid. The rating of waterproof is equal to IP23. Solid state voltage
regulation keeps excellent stability on changing load conditions. Fast response
automatically gives steady power to sensitive machine.
The Super Quiet series generators are motorized by Kubota
vertical, water cooled 4 cycle diesel engines which stick to all applicable
United States EPA regulations.
