Introducing the WSN-GEN S All-in-One Steam Generating Shrink Tunnel

The WSN-GEN S Steam Heat Tunnel For Shrink Sleeve Labeling

The WSN-GEN S Steam Heat Tunnel for shrink sleeve label and tamper evident band applications from American Film & Machinery is designed for middle, full body, and full body and cap shrink applications. The WSN-GEN S is an all-in-one tunnel that includes its own steam generator. The tunnel is a perfect addition to shrink labeling lines in manufactured goods industries including food and beverage, pharmaceutical, nutraceutical, health and beauty, consumer goods, and chemical products.

Reliable Shrink Performance

The WSN-GEN S is designed for simple setup where in-plant steam generation isn’t readily available. Equipped with 2 adjustable tier manifolds, the The GEN S directs the steam heat where needed to produce a precise, high quality finished appearance of PVC, PETG, OPS, and PLA labels and neck bands. The GEN S provides better contour than radiant heat and ensures a quality finish regardless of container size or shape.

Designed to Perform

The GEN S tunnel utilizes a 9” tall and 4” wide opening to accommodate a number of shrink sleeve products. The tunnel has a maximum temperature of 212°F and features high quality steam heating elements and an adjustable manifold for uniform heat distribution. Changing containers or labels isn’t an issue – tier adjustments and controls are done from the operator side of the tunnel, making adjustments safe, quick and easy.
