advantage：

1. The main engine is selected from the brand new imported American and Japanese compressors, with built-in safety protection, low noise, stability and durability. The electrical parts are all the original products of Schneider, France, to ensure that the machine works stably and has a long life.
2. The design area of radiator and heat exchanger shall be enlarged to ensure that the machine has enough cooling output under harsh environmental conditions. To prevent oil quality deterioration caused by high oil temperature, prevent thermal deformation of mechanical structure, and improve machining accuracy and stability.
