Pro-Shrink Tunnel
High-performance tunnel – fast and energy-saving

The DETLA-line allows shrink packaging to be produced quickly and easily with all shrink films (POF, PE, PVC, PET). The shrink tunnel systems are ideal for packaging industrial and food products that are shrink-wrapped in film. Our shrink tunnel systems are equipped as standard with heat-resistant transport rods and rotating chain rods. Thanks to the 3-dimensional convection air circulation system with adjustable air blower, the TLA series is designed for high-speed processing with semi-automatic or fully automatic packaging machines. State-of-the-art thermal insulation and energy recovery achieve efficient energy savings.

Technical details

  • Stepless adjustment of temperature and conveyor belt speed
  • Stepless adjustment of the recirculation fan
  • Energy-saving solid-state relay control (SSR)
  • 3-dimensional air flap system (top, bottom, side)
  • Automatic shut-off
  • Rotating chain rods (no sticking of the film to the product)
  • Adjustable ventilation flaps (heat control directly on the product)
  • Separately removable tunnel hood with click lock technology (easy maintenance)

Frequently asked questions about our pro shrink tunnel (DETLA/DETSS series)

The Pro shrink tunnel (DETLA/DETSS series) is designed for higher cycle rates and continuous industrial use. Unlike the Eco model, it offers more powerful heating systems, longer tunnel zones and optimised air circulation for particularly even shrink results – even with heavy or large-format products.

Ideal for:

  • Beverage packaging, cardboard bundles or cans
  • Large-volume and heavy products in industry, logistics and trade
  • Continuous operation with high utilisation (3-shift operation)

Can also be perfectly combined with fully automatic bundling machines or side sealers.

Compatible with:

  • PE shrink film (especially for heavy products)
  • Polyolefin fine shrink film (POF)
  • Environmentally friendly recyclable mono films

Depending on the model, heat is applied via hot air or contactless circulating air with variable control.

  • High-performance fan for optimum air distribution
  • Precise temperature control with PID regulation
  • Digitally adjustable conveyor speed
  • Robust stainless steel housing (optional)
  • Integrated safety system and automatic cooling

Designed for maximum efficiency and long-lasting use in continuous operation.

Thanks to its modular design, the Pro shrink tunnel can be flexibly combined with shrink wrapping machines, conveyor technology and palletisers. Optionally available with automatic tunnel adjustment to different product sizes.
