+ Middle, full body, and full body and cap shrink applications

+ Equipped with 4 adjustable tier manifolds

+ Accommodating 9” tall and 5” wide opening

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 4 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, PLA labels and neck bands. The GEN S provides better contour than radiant heat and ensures a quality finish.

Designed to Perform

The GEN S tunnel utilizes a 9” tall and 5” wide opening to accommodate a number of shrink sleeve products. The 4 adjustable steam manifolds direct steam horizontally, vertically, or radially to ensure 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.

Fully integrated 30KW boiler generates its own steam where in-plant steam isn’t readily available

Adjustable tiers direct steam heat where needed to product a precise, high quality finish

Steam exhaust can be monitored and adjusted to
specific shrink applications

High quality steam elements provide direct and efficient steam heat where needed regardless of container size or shape
