A heat/shrink tunnel, is an enclosed and heated area that is used to not just apply heat to an object, but create a heated local environment around an object. Heat tunnels are generally found above or enveloping a section of conveyor belt to allow for automated travel through the tunnel. The most common use for a heat tunnel is the activation of heat shrink labels, packaging, and tamper bands on a container; however, they are also used to cure paints and heat parts.  Shrink Tunnels  

The type of heat tunnel preferred is steam. Heat tunnels work by transferring energy from an electric boiler Electric Steam Boilers to an object within an enclosed area. The goal may be to a shrink film/label, cure a coating of paint, remove excess water/moisture, or any other application requiring immersion in heat but the principals remain the same. The amount of energy transferred depends on the output KW capacity of the electric boiler, the material being heated, and the residence time of the object in the tunnel.   

Steam tunnels use steam as a heat transfer medium. Steam is injected into the tunnel, enveloping any objects therein, and transferring heat to the object. Steam tunnels are suitable for shrink applications but may be less used for drying or curing applications.

Reimers is well suited to provide electric boilers to meet the tunnel industry needs.   Contact
