maseGENERATORSIS 6.16.1 kW 50 HzIS 7.17.1 kW 60 HzTHE INTERCOOLER W/AAssures the perfect functioning of the generator independentlyof the external ambient temperature, therefore the alternatorand the engine will work at ideal temperature optimizing theperformance and reliability of the gen-set.Control PanelThe gen-set control panel has short dimensions (86x124mm,3.4x4.9in.). It is supplied with 10mt wire shielded. Designed withthe most modern technology, it is supplied inside with a microchip.The keyboard is made by polyester shockproof with grade ofprotection IP54 and includes:• Hour-meter.• Start-stop button.• Alarm lamps and low oil pressure.• Engine and alternator high temperature alarm lampsEngine• Easy access in case of maintenance to the feeding system andlubrication, of the sea/water pump and the air filter.• Safety stop in case of low oil pressure.• Safety stop in case high water/exhaust gas temperature.• Double vibration dumping system.• Oil filter.• Oil drain pump.Alternator• Synchronous, 2 poles, self-regulated, brush less self-excited.• Rotor and stator epoxy resin coated against external agents.• Insulation class H.• High temperature coilings protection.Soundproof cabinA new project engineering design with a structure of a draw piece ofaluminum supporting, painted aluminum panels of high resistanceto external agents.Of limited weight and easy accessibility to the inner cabin in caseof maintenance services.Engine 50 Hz 60HzModelTypeCylinders (nr.)Cylinder block materialBore (mm. - in.)Stroke (mm.- in.)Displacement (cc. - CID)KUBOTA Z482Diesel 4 stroke2Cast iron67 - 2,668 - 2,6479 - 29,2Power (hp) 11,1 13,3RPM 3000 3600Injection systemEngine head materialSpeed governorLubrication systemEngine stop systemFuel pumpFuel pump discharge (cm. - ft)Starting battery (Ah-V)Starter (kW-V)Max. inclinationWater pump flow (l/min. -gl/min.)Alternator 50 Hz 60HzTypeCoolingSynchronous, 2-polesself excitedAir/water ( Intercooler W/A )Voltage (V) 115 - 230 120 - 240Frequency (Hz) 50 60Amps 53 - 26,5 59,2 - 29,6Max. power (kW) 6,1 7,1Continuous power (kW) 5,6 6,6Battery charger output (A-V)Power factor ( cos ø )Insulating classVoltage stabilityFrequency stability10-121H±10%±5%Cooling systemIndirectCast ironCentrifugal mechanicalForcedStop solenoidElectric70 - 2,345 - 120,7 - 1230°20 - 5,3The cooling of the engine is based on a closed inner flow ofcoolant.The system is based on a heat exchanger seawater/coolanttype, of cupronickel, where the thermal exchange occursbetween the two liquids.Two separate pumps contribute to the flow of the coolant andthe sea water. The cooling of the air inside the gen-set is obtainedthrough a seawater/air heat exchanger. This provides theefficacious cooling of the alternator and the optimal temperaturefor the best performance and reliability of the gen-set despiteits on board allocation and room temperature.
