1. Noise Level Requirements
Verify dB(A) ratings match local regulations (typically 60-75dB at 1m for silent models).Three-layer soundproof enclosures can achieve ≤65dB operation
2. Fuel Efficiency
Look for low-consumption diesel engines.Compare runtime per tank at 50-75% load
3. Mobility Needs
Trailer-mounted options for temporary sites.Containerized designs for permanent installations
4. Protection Features
Essential safeguards: overload/short-circuit protection.Advanced controls like ATS (Automatic Transfer Switch)
5. Environmental Conditions
Weatherproofing for outdoor use.Corrosion-resistant coatings (3-layer spray process)
6. Certification & Warranty
ISO 9001 certified manufacturers.6-12 month warranty coverage standard
7. After-Sales Support
Availability of technical assistance.Local service network for maintenance
8. Specialized Requirements
Combined functions (e.g., lighting towers/flood pumps).Marine-grade options for coastal areas
Recent models (2025) emphasize modular designs allowing power stacking and smart monitoring integration. For urban use, prioritize compact footprints and vibration reduction technologies. Industrial applications may require synchronized parallel operation capabilities.
