The tempering and cooling section is made of blowers, uppers and lowers, under which a steel rolls conveyor with isolating cloth, moves the glass.
The blowers are mounted on proper motorised independent frames, permitting the distance regulation between the blowers and the glass and equipped with blow pressure measuring devices.

In the tempering section are installed n°2 fans driven by alternating current motors with Inverter.
Two independents fans allow to eliminate distribution valves: directly by supervision it is possible to manage precisely and easily the fans, optimizing the upper and lower air flow.
The Inverter allow to regulate exactly the motor rounds number and reduces power consumption.
The alternating current motor lowers the maintenance expenses eliminating the periodical brushes substitutions of the motors.
To minimize the consumption automatic ON/OFF valves are installed to the fans air inlet.
