mas ma s e GENERA TORS ies ser TNV IS 7 IS 8.1 6.7 kW 50 Hz 7.8 kW 60 Hz THE INTERCOOLER W/A Assures the perfect functioning of the generator independently of the external ambient temperature, therefore the alternator and the engine will work at ideal temperature optimizing the performance and reliability of the gen-set. Control Panel The gen-set control panel was designed to include, in one single panel, the switches, control devices and the protection devices The components are the following : • Engine cut-off module for automatic stop of engine in case of high water 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 and lubrication, 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. • Rotor and stator epoxy resin coated against external agents. • Rotor dynamically balanced. • Insulation class H. Soundproof cabin A new project engineering design with a structure of a draw piece of aluminum supporting, painted aluminum panels type 5754 of high resistance to external agents. Of limited weight and easy accessibility to the inner cabin in case of maintenance services. Engine Model Type Cylinders (nr.) Cylinder block material Bore (mm. - in.) Stroke (mm.- in.)

The system is based on a heat exchanger seawater/coolant type, of cupronickel, where the thermal exchange occurs between the two liquids. Two separate pumps contribute to the flow of the coolant and the sea water. The cooling of the air inside the gen-set is obtained through a seawater/air heat exchanger. This provides the efficacious cooling of the alternator and the optimal temperature for the best performance and reliability of the gen-set despite its on board allocation and room temperature.
