1.  Air pressure: we can increase the air pressure by reducing the pressure loss in the air path and reducing the area of the air outlet.

2.  The distance between the nozzle of the glass tempering chiller and the glass surface: we can adjust the distance between them by adjusting the height of the chiller. The thinner the glass to be tempered is, the smaller the distance between the air nozzle and the glass surface should be, in order to increase the cooling intensity.

3.  The temperature of environment where the glass is tempered: the level of ambient temperature is inversely proportional to the cooling intensity.
