■Digital flow switch to save energy!
Flow control is necessary for promoting energy saving in any application.
Saving energy starts from numerical control of the flow consumption of equipment and lines and clarification of the purpose and effect.
● Flow control of N2 gas to prevent lead frame oxidation
● N2 blow prevents distortion of camera image due to air turbulence.
