Sleeve-Steam-Tunnels

For uniform shrinkage

Gentle shrinkage processes for sensitive products

Our DESPC-1500 and DESPC-2500 line stainless steel steam tunnels are extremely easy to operate and maintain, waterproof and easy to clean. They are suitable for the efficient shrinking of full-body shrink bands on almost any type of container with almost any shrink film material. The low-pressure steam drum distributes the steam evenly throughout the tunnel thanks to the integrated steel pipe construction. Each section of the tunnel contains steam pipes that are adjustable in both height and steam output. The tunnel housing and the water collection plate for collecting condensation are made of rustproof 304 stainless steel.

Frequently asked questions about our sleeve steam tunnel

A sleeve steam tunnel uses saturated steam to evenly and gently adapt applied shrink sleeves to containers. The steam ensures precise, wrinkle-free shrinkage – even with complex product shapes such as bottles, jars or tubes.

A steam tunnel is ideal for products with irregular shapes or heat-sensitive contents, e.g.:

  • Glass bottles and PET bottles
  • Cans or jars with safety closures
  • Cosmetics, beverages, household or pharmaceutical products
  • Gentle shrinking process using steam instead of dry heat
  • Perfect fit for difficult shapes
  • Reduced risk of deformation or shrinking errors
  • Even temperature distribution and fast availability
  • Particularly suitable for highly refined or printed sleeves

Yes – our models are made of stainless steel, are waterproof and easy to clean. They have large viewing windows for process control and meet the highest requirements in the food and pharmaceutical industries.

Absolutely – the devices can be flexibly combined with sleeve labeling machines, conveyor technology or labelling machines. Variants with multiple steam zones or closed designs are available as options.
