Venting system

Back to Blog

Venting is used for the timely removal and disposal of volatile tin components. It is not necessarily mandatory in the tin bath, but it definitely contributes to its efficiency: when volatile tin returns from a gaseous to a metallic state in the cooler zone, the metal particles (tin drips) can contaminate the glass surface and cause defects. This can be prevented by directing the flow direction of the atmosphere away from the exit end and toward the venting tubes.
The special feature of CNUD EFCO GFT’s venting system is that the extraction is controlled and thus has no negative influence on the sensitive pressure conditions in the tin bath.
