Operating diesel generators near the sea may seem complicated, but the main risks are salt spray, humidity, wind-blown sand, and temperature fluctuations. When selecting a diesel generator for a coastal project, it’s important to consider these factors in both procurement and maintenance.
1. Understand Coastal Environment Challenges for Diesel Generators
Salt Spray Corrosion
Coastal air contains high levels of salt, which can corrode metal components over time.
Solution:
· Choose stainless steel or aluminum alloy materials
· Apply anti-corrosion coatings to external surfaces
· Regularly inspect and treat any rust-prone parts
High Humidity and Temperature Variations
High humidity and large temperature differences can affect electronic components, cause fuel condensation, or lead to short circuits.
Tips:
· Select control panels with appropriate IP protection ratings
· Place desiccants or moisture absorbers inside control cabinets
Wind, Sand, and Dust
Strong coastal winds carry sand and dust that can clog air filters and cooling systems.
Best Practices:
· Use high-efficiency air filters
· Clean coolers and air intakes regularly
· Protect exposed pipes and ducts with covers or mesh
2. Coastal Diesel Generator Selection Tips
Corrosion-Resistant Design
· Use stainless steel, aluminum, or anti-corrosion coated enclosures
Power and Load Matching
· Choose rated generator power based on total electrical load
· Leave 20–30% capacity margin for startup currents or temporary load fluctuations
Cooling and Ventilation Systems
· Water-cooled systems: high efficiency, but must protect against water corrosion and condensation
· Ensure proper ventilation for long-term stable operation
Additional Practical Tips
· Low-noise or silent-enclosure models are ideal for residential areas or marina docks
· Optional weatherproof and dustproof covers can extend generator lifespan
3. Installation and Maintenance Recommendations
Installation Location
· Avoid direct exposure to sea winds to reduce salt spray impact
· Mount on elevated or moisture-resistant platforms to prevent water accumulation
Routine Maintenance
· Treat and clean external surfaces, air filters, and enclosures
· Check lubricants, batteries, and fuel systems regularly
· Inspect IP protection seals and reseal if necessary
Maintenance Tips
· Run generators lightly when idle; change anti-corrosion oil quarterly
· Keep spare consumables (filters, oil filters, bolts) on hand for quick replacement
