The (dual-zone) FR221 hot air shrink tunnel is the result of 25 years of experience acquired by oue company in the field of shrink-wrapping. Used ‘downstream’ of the horizontal wrapper process, they ensure the optimal shrinking of products wrapped in barrier or non-barrier film.
Their frames are made entirely of stainless steel and consist of 2 sheets separated by thermal insulation. They are also fitted with air curtains at entrance and exit points of conveyors. These confine heat inside, prevent heat loss and allow wrapped products to cool down rapidly. The JNJ FR221 shrink tunnels can be supplied with two blowing roof types for optimal shrinking regardless of the shape of products.
Perfectly integrated within the ES101 horizontal wrapper
Downstream from the ES101 wrapper process, temperature adjustments of heating areas, along with conveyor speed, are set according to the selected product recipe.
