Super Air Wipe for a Galvanizing Application

Wire galvanizing machine

Section of wire galvanizing machine

I saw this machine in the faraway corners of a Thai wire manufacturer’s facility.  The manufacturer galvanizes their wire to protect it from corrosion and physical damage, and after the hot dip process, the wire must be wound.  But, before the wire can be wound, it travels through this machine, which serves as a sort of quality control for the finish of the galvanization.

As the wire passes from bend to bend, it approaches a final stage in which any excess zinc is removed from the OD of the wire, which, prior to my visit looked like the photo below.

This short cylinder with a center hole to accept the wire  is an inefficient, homemade blow off

The performance of this homemade blow off was unrepeatable, and the end user had questions about whether the compressed air was being used efficiently.  To find out, we connected a Digital Flowmeter, and found that this homemade device was consuming twice what a comparable Super Air Wipe requires at the same pressure.

We then connected a Super Air Wipe to find that the blow off was not only stronger, but more uniform from the EXAIR unit.  And, the clamshell design of the Super Air Wipe can allow the installation to occur at any point along the process, without requiring that the wire is “threaded” through the Air Wipe.

If you have a similar application, or one that you think may be candidate for an EXAIR solution, contact an EXAIR Application Engineer.
