An open-frame diesel generator set can be simply understood as a conventional or standard model.

Advantages: 1) easy to move and lightweight; 2) simple structure, easy to manufacture, maintain and repair;

Disadvantages: 1) there is no acoustic enclosure, so the noise level is usually high because there are no sound insulation or vibration reduction measures, making it suitable only for environments with low noise-control requirements; 2) it does not provide strong waterproof, windproof or dustproof performance.

A silent diesel generator set can be simply understood as a box-type design, with wheels or a trailer. Silent units usually adopt an enclosed structure, including one engine compartment and one or more alternator compartments.

Advantages: 1) low noise, mainly suitable for low-noise environments such as RV conversions, advertising vehicles, medical vehicles, offices, residential areas, etc.; 2) better waterproof, windproof and dustproof performance;

Disadvantages: 1) heavier weight; 2) more difficult to manufacture, maintain and repair.
