LP Marine Generator

Code:

Product Overview

The LP Marine Generator Engine series is a reliable range of compact diesel engines, specifically designed for power generation in marine environments. With fixed speeds between 1500–3600 r/min and power output ranging from 7.5 to 38.6 kVA, these engines are engineered for continuous operation in demanding conditions—from tropical heat up to 52°C (122°F) to sub-zero temperatures down to -32°C (-25.6°F).

Key Features

  • Marine-Optimized Design: Purpose-built for generator applications in harsh marine environments
  • Compact and Durable: Lightweight footprint with robust build quality and long service intervals (up to 500 hours)
  • Flexible Cooling Options: Heat exchanger cooling standard; keel cooling available as an option
  • Low Maintenance: Spin-on oil filters, individual fuel injection pumps, and easy-access service points
  • Flexible Electrical Systems: 12V standard, with optional 24V setups and additional electrics available
  • Raw Water Cooling System: Belt-driven raw water pump and thermostatic control for marine-grade performance
