Super Quiet Performance at 63-65 dB (A) |
|
| Kubota's line of low noise, heavy-duty, 4-pole diesel generators
are powered by Kubota's own cleaner emission and highly durable E-TVCS
combustion system diesel engines. The SQ series are quiet, efficient, and
provide a longer service life. Excellent Load Characteristics The PMG (Permanent Magnet Generator) exciter system responds instantly to load changes. Quick response automatically provides stable power to sensitive equipment. Over-Sized Muffler The over-sized muffler lowers sound levels. A special two stage muffler system is used in generators powered by V3300 diesel engine to further reduce noise. Quieter Cooling Fan Kubota reduced fan related noise with a larger-diameter, slower speed fan, maintaining the same cooling effect as a fan running at normal speed. A long air cleaner inlet hose keeps low frequency noise down. How quiet is that? SQ Series generator sets, running at full load, measure 63 dB (SQ1130) to 65 dB (SQ3330) at 7 metres/23 feet. That's slightly louder than a quiet office (50-60 dB), and in the range of normal conversation (50-65 dB). |

| Easy maintenance | |
|---|---|
| Easy One Side Maintenance Engine oil and coolant drain extensions are provided to ease regularly scheduled maintenance. Oil gauge, oil filter, oil replenishment port, fuel filter, water reserve tank, battery and air cleaner are all located on one side for quick inspection and maintenance. |
|
| Safety | |
| All engines for SQ Series Generators are ECU-controlled. Automatic
shutdown of the engine will occur if abnormal conditions or if the load centre
doors are opened during operation. Automatic shutdown for: - abnormal oil pressure - abnormal water temperature - excessive speed - broken fan belt Designed with Safety in Mind The fully covered load center houses all the outlets, compression terminals and circuit breakers. To prevent inadvertent contact with the terminals, the receptacles are divided in a separate section. GFCI receptacles are standard equipment to further enhance operator safety. Safety Door Interlocks Safety door interlocks automatically shut down the engine if the load center doors are opened during operation. For safe, unattended operation, the maintenance doors are equipped with safety interlocks. Safe enclosure Large, removable doors feature heavy duty steel hinges and recessed locking door latches. These safeguard against unauthorized use and allow safe, unattended operation and easy maintenance. |

| Operator friendly | |
| Transportability One-point lifting eye makes it easy to transport all SQ Series Generators. The advanced design and superior engineering minimizes both space and weight. Transportability is improved with slots on each side of the machine for safe forklift truck transportation. Four tie down points and sturdy lifting eyes further enhance hoisting and transportation. Base Mounted Fuel Tank The SQ series is equipped with large capacity bottom mounted fuel tanks to prevent fuel spills inside the enclosure. The locking fuel cap is placed to avoid damage and simplify refueling. Automatic Air-Bleeding Every time the engine key is turned on, air is automatically purged from the fuel system. Locking Control Panel Door Shields instrument panel from the elements and permits observation of all key functions without opening the door. Automatic Start System Provision for automatic/remote start (2 wire closed to run) |
