Electrical tunnel

Shrink tunnel sleeve consists of infrared panels combined with hot air blowers. The length of the tunnel is sized to the speed of production to be achieved and to height of the sleeve to be shrunk.

The general characteristics are: 

  • Tunnel structure in stainless steel
  • Pre-chamber of heating with infrared panels
  • Display for adjusting temperature of infrared
  • Hot air blowers with independent settings
  • Supports for adjusting blowers position

Steam tunnel

Steam shrinking tunnel, equipped with a new technology that allows the complete management by using electronic devices.
This tunnel may be composed of multiple modules, all with independent temperature, and the length of the tunnel is sized to the speed of production to be achieved and to height of the sleeve to be shrunk.
The tunnel can be integrated within the modules, with electrical heaters which allow to perform the heat shrinking with a low emission of steam.

The general characteristics are:

  • Tunnel structure in stainless steel
  • Modules of the tunnel with independent temperature
  • Electronic control and management of steam
  • PLC for displaying tunnel settings. This PLC allows to store all the parameters of temperature for each format
  • Modulating valves for constant control of steam injection
  • Aspiration steam managed by inverter
  • Doors closing tunnel made of glass, allowing the visualization of the internal conditions of heat shrinking
  • “Outdoor” settings of internal steam pipes, with counters for numerical control positioning
  • Overheating steam by heating elements
  • Centralized draining of condensate and excess steam
