2. Function introduction

2.1 Unit features

● The gas generator set is suitable for operation in a range of multiple environmental conditions, and its economic performance is better than that of the existing diesel engine; The unit can quickly respond to load changes and deal with more complex conditions.
● The gas generator unit adopts the integrated partition box design, the box can meet the operation of multiple environmental conditions, and has the functions of rain proof, sand dust proof, mosquito proof, noise reduction, etc. The box body is designed and produced with special structure and materials of high strength container.
● The shape of gas generator box meets the national transportation standard.

2.2 Unit cooling

● The cooling system of the gas generator set adopts the fully independent heat dissipation design, that is, the single intercooling heat dissipation system and the cylinder liner heat dissipation system operate independently, so as to meet the unit's single repair and maintenance without affecting the operation of other units, which greatly meets the unit's maintenance and practicability.
● The hot air of the cooling system is discharged upward in a unified way to avoid hot air backflow and ensure the normal operation of the cooling system of the unit.
● The cooling system increases the heat dissipation area and heat dissipation under normal heat dissipation conditions, and the cooling effect can better meet the normal operation of the unit under various extreme environmental conditions.
