Sotemapack manufacture a wide range of electrical shrink tunnels, available with 500-to-2500-mm inlet mouths, in compliance with the product size to be packed, and shrink hoods in variable lengths based on production rate required.
• Tunnel conveyor in steel wire netting (or slats coated with a silicone sheath) equipped with mechanical variable speed gear-motor for adjusting the conveying speed.
• Heat shrink chamber, duly insulated through mineral wool, equipped with suction fan and further uniform recirculation of the air around the pack in a closed circuit. A set of finned heat resistors provides for air heating. Their location allows rapid replacement during maintenance. Air can be directed both sideways and towards a central position under the tunnel, by means of special baffles according to a variety of problems that can arise during shrinking cycle.
