Selection notes for buyers
Start with duty and output
Shortlist U.S. EPA Tier 3 generator engines around 4-3,300 kWe, then compare prime, standby and frequency ratings against the actual load profile.
Check site constraints
Review diesel availability, cooling package, emissions rules and service support before treating two similar kWe ratings as interchangeable.
Match the alternator and package
After the engine shortlist is clear, confirm voltage, frequency, alternator frame size and radiator or canopy requirements for the complete generator set.
Use this shortlist in a generator-set project
The model list is a specification starting point. Haifeng Machinery can help confirm the engine rating, alternator match, cooling system and emissions requirement for standby, prime or continuous-duty projects.
