Shrinks difficult sleeve over shaped bottles. Steam delivers a better shrink than pure electric (also known as infrared or radiant). The addition of a small steam generator and specially designed steam tubes to our Infra red Tunnel gives this better shrink but at an affordable price.
Several sizes are available and our 48 inch Tunnel has dual zones for both the infra red heaters and the steam tubes to enable gentle even shrink at the entrance to the tunnel and to finish with a hotter exit.
The further advantage to the combination Hybrid tunnel is that only a little steam is used and so the process is much drier than it would be with a steam only tunnel and also the shrinking is completed in much less space than conventional tunnels.
