Frequently Asked Questions

The selection of the right type of shrink tunnel depends on your operation. Product type, speed, floor space, connectivity, and automation options all figure into the decision. While the heat source is just one of the considerations, the production (and loss) of heat in hot water shrink tunnel can create humidity in the work environment and elevate utility costs, so it’s important to consider your operating environment carefully before deciding. Shrink tunnel technology has been around for a long time without a lot of significant changes in energy management. We understand the impact today’s energy costs have on packaging operations, so we designed the AutoShrink 98 tunnel with an energy-efficient electric heating unit and steam recovery system to help lessen operational utility loads.
