Mase IS 6.5 / 7.6 Diesel-Powered Generator
(6.5kW at 50Hz / 7.6kW at 60Hz)
 

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:
. 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 an 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 of 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 aluminium supporting painted aluminium panels type 5754 of high resistance to external agents. Of limited weight and easy accessibility to the inner cabin in case of maintenance services.

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 temperatures optimising the performance and reliability of the genset.

  Cooling System

The cooling system of the engine is based on 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 genset 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 genset despite its on board allocation and room temperature.
