DaZe Power Marine Diesel Generator Sets: Technical Advantages

The Dazai Power marine diesel generator sets are characterized by classification society certification, seawater/freshwater recirculating cooling, salt mist resistance and vibration resistance, intelligent control, and low noise and high efficiency. They are suitable for main and emergency power supply for small and medium-sized vessels, capable of stable operation in high humidity, high salt mist, and compact spaces at sea, significantly outperforming ordinary land-based sets in terms of comprehensive reliability and cost-effectiveness. The following analysis delves into the key technical aspects:

One: Enhanced Vessel Classification Compliance and Reliability

• Authoritative Ship Inspection and CertificationOur full line has obtained CCS (China Classification Society) certification, is compatible with ABS, BV, DNV, and other international classification society standards, and is designed and manufactured in compliance with IMO and maritime safety regulations, ensuring ship compliance operations and expedited customs clearance.

• Salt-spray and vibration-resistant designKey components (cylinder, radiator, electrical elements) are coated with anti-corrosion materials and sealed, suitable for marine environments with high salt mist and humidity; the body and base are equipped with rubber shock-absorbing pads, resistant to ship vibration during navigation, with a low failure rate during continuous operation.

• Long-life core componentsStrengthened crankshafts, pistons, and valve components, with an engine overhaul cycle of ≥10,000 hours and maintenance intervals of up to 200 working hours, reducing maintenance costs for oceanic operations.

Cooling and Thermal Management System

• Saltwater Freshwater Recirculating CoolingThe mainstream models utilize a marine-freshwater heat exchanger, featuring anti-corrosion treatment on the seawater side and a closed-loop system on the freshwater side. This design improves the heat dissipation efficiency by 30% compared to conventional air-cooled systems, preventing freshwater loss and scaling, and is suitable for long-duration voyages.

• Intelligent Temperature ControlSilicone oil fans automatically adjust their speed with water temperature, enhancing heat dissipation during high loads and reducing energy consumption and noise during low loads, adapting to the temperature variations in marine environments.

• Extreme operating conditions compatibleThe product supports stable operation within a temperature range of 25℃ to 45℃, and some models are equipped with low-temperature preheating devices to ensure reliable cold start in cold sea areas.

III. Power and Fuel System Optimization

• High Pressure Common Rail + Electronic Throttle ControlHigh-pressure common rail precise fuel injection, electronic throttle response time < 0.5 seconds, voltage fluctuation ≤ ±3% under sudden load (such as anchor winch, air conditioner), ensuring stable power supply to critical equipment like navigation and communication.

• Efficiency in Combustion EnhancedThe improved nozzle reduces spray particle size by 10%, boosts combustion efficiency by 12%, and achieves fuel consumption of 200-230g/kW・h under economic load, a 15%-20% reduction compared to traditional models. A 50L fuel tank allows continuous operation for 8-12 hours.

• Fuel CompatibilityAdaptable for marine diesel from 0# to -35#, catering to varying sea temperature requirements, and reducing fuel procurement and storage costs.

IV. Smart Control and Safety Protection

• Comprehensive Security ProtectionWith multiple protections including overload, short circuit, under-voltage, over-temperature, low oil pressure, and over-speed, the equipment automatically shuts down and alarms in case of faults, preventing equipment damage and safety accidents.

• Remote and Automation FeaturesOptional remote control startup, ATS automatic transfer switch, millisecond-level switching during power outages, compatible with unmanned engine rooms and emergency power supply scenarios.

• Smart Monitoring PanelReal-time display of parameters such as RPM, voltage, current, water temperature, and oil pressure, with support for fault diagnosis and data recording, facilitating maintenance and operation management.

V. Low Noise and Emission Control

• Silent DesignThe company has adopted wet mufflers and soundproofing covers, achieving noise control between 57-65dB(A) at a distance of 3 meters. This optimizes the working and living environment for crew members, in compliance with ship noise regulations.

• Environmental EmissionThe G4 model is equipped with a DPF (diesel particulate filter) + SCR (selective catalytic reduction) system, achieving NOx and particulate emissions that meet the IMO Tier III standard, compatible with global environmental requirements.

Space Compatibility and Easy Installation

• Compact and lightweightThe aircraft's volume is reduced by 15%-20% compared to land-based models of the same power, weighing 10%-15% less, making it suitable for ships with compact engine rooms and easy for hoisting and layout.

• Modular designThe side-opening maintenance doors and centralized maintenance points, with universal wear parts, reduce the difficulty of marine repairs and enhance maintenance efficiency.
