The state-of-the art in marine equipment The growing demands of the marine marketplace demand a big, robust power producer. As the world’s yachts grow more sophisticated, their power generation system must keep pace. Northern Lights generator sets are based on world-class components - including industrial strength base engines and generator ends. Our exclusive marinization process ensures reliable, clean power no matter what your vessel requires. Low profile for maximum engine room flexibility Northern Lights’ revolutionary base frame design creates the most compact, best looking power generation set on the market. Our optional sound enclosures and compound mounts save even more space and virtually eliminate vibration noise. Northern Lights provides maximize power efficiency while using minimal engine room space. Component Specific Features Engine block • Six cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavy-duty industrial engine blocks. • Balanced alloy steel crankshaft with induction hardened journals and rolled fillets. • Replaceable valve seats and guides. • Strong three ring steel pistons for long-life reliability. • Gear-driven seawater pump. • Drive belt powers the alternator and freshwater pump. • Replaceable, strength-optimized wet cylinder liners for long life and low rebuild costs. Fuel system • Electronically controlled high-pressure fuel injection system provides individual control in each cylinder for low exhaust emissions and superior fuel economy. • High torque at low revolutions. (1800 or 1500 rpm) • Full flow spin-on duplex elements. • Gear driven fuel transfer pump with primer. • Flexible fuel lines routed to fuel manifold on base frame for easy installation of vessel’s hard piping. Lubrication system • 500 hour oil change interval when fuel and oil requirements are met. • Positive displacement gear-type oil pump. • Full ow, spin-on oil lter. • Centrifugal oil cleaner to extend oil change intervals. • Freshwater, plate-type, full ow oil cooler reduces heat and thermal breakdown of lube oil. • Large capacity oil pan. • Floating, cast aluminum, rocker cover traps valve noise with a separate closed breather system. • Lube oil drain for easy changes. • Dry air lter silences intake noise. • Dry exhaust elbow available in 5 inch (127 mm) or 6 inch (152 mm). • Aftercooler with marine quality, cupro-nickel, single pass element. • Turbocharged for increased output. Cooling system • Freshwater cooling system with twin thermostats for quicker warm-ups. • Heat exchanger cooling includes: Gear driven, flexible impeller seawater pump. Easy to clean, tube-type cupro-nickel heat exchanger. • Cast aluminum expansion tank with brass ller neck. Cast-iron exhaust manifold has single pass freshwater ow for even temperature control, fast warm-up and no hot spots. • Zinc anode electrolysis protection. Electronic control system For the ultimate in system management and monitoring, the M1306 series generator sets are equipped with an Electronic Control Unit (ECU). The ECU controls the electronic engine functions and provides a SAE J1939 data stream of engine information that can be displayed on an optional system monitor panel. Superior PMG generator ends Northern Lights generator ends achieve ±0.5% voltage regulation. All have low temperature rise ratings to meet or exceed marine requirements. All M1306’s have Permanent Magnet Generators for 300% short circuit capability required for classed vessels. Complete unit testing Northern Lights generator sets are thoroughly factory tested and go through a complete quality control program to ensure your satisfaction with the best built marine generator on the market today. DC electrical system • Engine supplies SAE J1939 data stream through a CAN bus plug for optional engine monitor. • Negative ground, 24 volt DC system with circuit breaker, starter motor and battery charging alternator with regulator. Isolated ground optional. • Standard digital controller displays engine hours, coolant temperature, oil pressure, DC voltage, and includes start-stop controls. Increased ease of paralleling through controller. • Engine and panel are pre-wired with terminal strips. • Low oil pressure and high coolant temperature safety shutdown system included in controller. • Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design. • Generators meet or exceed class society standards. All have class H insulation, accessible diodes, oversized ball bearings, marine grade shafts and conservative 90°/50° heat rise ratings. • Engines and generators are torsionally matched for long life. • Automatic voltage regulator gives fast response to electrical load changes. Voltage is regulated to ±0.5% (one half of one percent) over the entire range from no load to full load. • Isochronous electronic governor for 0% AC frequency droop. • PMG (permanent magnet generator) to power AVR for 300% short circuit capability for “classed” vessels. Special equipment • Standard hydrolastic mounts isolate 98% of hull vibration. • Welded steel base pan. Easy to mount and keep clean. • Belt guard protects operator even on sets in sound enclosures. • Sparkling white IMRON® polyurethane paint for protection and visibility. • Operator’s and parts manuals. World-Class options • Make your power generator system as unique as your boat. Northern Lights offers a comprehensive list of optional equipment including high power PTO’s, super attenuated sound enclosures, customizable panels, and much more. Classification standards • Meets or exceeds US EPA Tier III emission standards. • IMO 2 compliant. • Available certification from all major class societies including ABS, Lloyds Register, Germanischer Lloyd, DNV, Bureau Veritas, RINA, CCS and more (consult factory for additional societies and application information).
