maseGENERATORSTNV seriesIS 27 IS 3150 Hz 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 was designed to include, in one singlepanel, the switches, control devices and the protection devicesThe components are the following :• Engine cut-off module for automatic stop of engine in case of highwater temperature, low oil pressure, high alternator temperature.• Hour-meter.• Start-stop button.• Breaker for protection against of overload or short circuit.• Thermal switch.Engine• 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 and fuel filters of easy access.• Oil drain pump.Alternator• Synchronous, 4 poles, brush less self-excited, electronic voltageregulator (AVR)• Rotor and stator epoxy resin coated against external agents.• Rotor dynamically balanced.• Insulation class H.Soundproof cabinA new project engineering design with a structure of a draw piece ofaluminum supporting, painted aluminum panels type 5754 of highresistance to external agents.Of limited weight and easy accessibility to the inner cabin in caseof maintenance services.Engine 50 Hz 60 HzModelTypeCylinders (nr.)Cylinder block materialBore (mm. - in.)Stroke (mm.- in.)Displacement (cc. - CID)Yanmar 4TNV98Diesel 4 stroke4Cast iron98 - 3.8110 - 4.33319 - 169.4Power (hp) 47 56RPM 1500 1800Compression ratioCombustion systemEngine head materialSpeed governorLubrication systemOil sump capacity with filter(l -gl)Engine stop systemFuel pumpFuel pump discharge (cm - ft)70Fuel consumption (l/h - gl/h) 10,8 - 2,3 12,4 - 2,7Air intake (l/h - gl/h) 2500 - 547 3000 - 656Starting battery (Ah - V)Battery charger (A-V)Starter (kW-V)Max. inclination80 - 1240 - 122.3 - 1230°Water pump flow (l/min. - gl/min.) 40 - 8.8 45 - 9,9Alternator 50 Hz 60 HzSynchronous, 4-poles,Typebrush less self-excitedElectronicRegulationCoolingAir/water ( Intercooler W/A )Voltage (V) 115 - 230 120 - 240Frequency (Hz) 50 60Amps 252 - 126 283 - 141Max. power (kW) 29 34Continuous power (kW) 27 31Power factor (cos ø)Insulating classVoltage stabilityFrequency stabilityCooling system18:1Direct injectionCast ironCentrifugal mechanicalForced10.5-2.3Stop solenoidElectric1H±2%±5%The 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.
