Product catalog summary
Control Panel
The generator set (gen-set) control panel integrates switches, control devices, and protection devices into a single panel. Key components include an engine cut-off module for automatic engine stop in case of high water temperature, low oil pressure, or high alternator temperature, an hour-meter, a start-stop button, a breaker for overload or short circuit protection, and a thermal switch.
Engine
The engine design allows easy access for maintenance to the feeding system, lubrication, sea/water pump, and air filter. It includes safety stops for low oil pressure and high water/exhaust gas temperature, a double vibration damping system, easily accessible oil and fuel filters, and an oil drain pump.
Alternator
The alternator is synchronous, 4-pole, brushless, and self-excited with an electronic voltage regulator (AVR). It features epoxy resin-coated rotor and stator for protection against external agents, dynamic rotor balancing, and insulation class H.
Soundproof Cabin
The soundproof cabin is designed with a lightweight aluminum structure and panels resistant to external agents, providing easy access for maintenance.
Intercooler W/A
The intercooler ensures optimal generator performance regardless of external ambient temperature, maintaining ideal temperatures for the alternator and engine.
Cooling System
The engine cooling system uses a closed inner flow of coolant with a seawater/coolant heat exchanger made of cupronickel. Two separate pumps facilitate coolant and seawater flow, and a seawater/air heat exchanger cools the air inside the gen-set.

Of limited weight and easy accessibility to the inner cabin in case of maintenance services. The cooling of the engine is based on a closed inner flow of coolant. 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.
