9EKOZD 60 Hz / 7EFKOZD 50 Hz

Product catalog summary

Engine Features
The generator is diesel-fueled and certified by the EPA to meet Tier III marine auxiliary standards. It features a three-cylinder, four-cycle engine with a closed cooling system and a heat exchanger. An electric fuel lift pump and lifting eye are included.

Generator Features
The generator includes a remote start 12-pin connector, Class H insulation, multivoltage adjustability, and voltage regulation of ±1.0%. It also has radio suppression capabilities.

Advanced Digital Control Features
The ADC IId is designed for sophisticated electronics, featuring a 12 x 2 LCD display, sealed connectors, and selectable CANbus outputs. It allows remote monitoring of fault conditions and includes a pushbutton dial for configuration.

Optional Accessories
Available accessories include an aluminum sound shield, remote digital gauge, siphon break, ignition protected starter, and circuit breakers.

Generator Weights and Dimensions
Without the sound shield, the generator weighs 211 kg (wet) and measures 827 mm in length. With the sound shield, it weighs 249 kg and measures 865 mm in length.

Generator Ratings
The 9EKOZD model operates at 60 Hz with a power output of 8.5 kW, while the 7EFKOZD model operates at 50 Hz with a power output of 7 kW.

Engine Specifications
The engine is a 4-cycle, naturally aspirated type with three cylinders and a displacement of 1.028 L. It has a compression ratio of 24.5:1 and operates at 1800 rpm for 60 Hz and 1500 rpm for 50 Hz.

Cooling System
The cooling system has a capacity of 3 L and features a belt-driven seawater pump with a 10-blade impeller.

Fuel System
The fuel system includes an electric fuel shutoff solenoid and pump, with a maximum recommended fuel lift of 1.2 m.

Lubrication System
The oil pan capacity is 2.5 L, and the system uses a pressure, trochoid pump.

Operation Requirements
Air requirements for engine combustion are 1132 L/min for 60 Hz and 934 L/min for 50 Hz. The maximum allowed exhaust back pressure is 14.2 kPa.

Fuel Consumption
At 100% load, the 60 Hz model consumes 3.4 Lph, while the 50 Hz model consumes 2.6 Lph.

Alternator Features
The alternator is brushless with a rotating field design, vacuum impregnated windings, and dynamically balanced rotors. It is mounted on a drip-proof tray and equipped with a four-lead reconnectable stator.

Advanced Digital Control IId Features
The controller integrates genset control and voltage regulation, with selectable outputs and a USB interface for software updates. It includes real-time diagnostics and a maintenance minder.

Accessories
The sound shield provides effective silencing and ease of access for servicing. A siphon break is mandatory for generators installed below the waterline. Line circuit breakers protect against overload, and a ship-to-shore switch allows for immediate power source switching.
