Among the many extensive advantages of the new generation of khs shrink tunnels that give this system a great deal of future potential is its modular design with a basic platform which can be extended as required. Khs uses adjustable hot air nozzles. The air flow can be set exactly as required to fully suit the individual pack format with regard to both height and width. The hot air nozzles are positioned manually by adjusting spindles and using a digital position indicator. Depending on the size of the shrink tunnel this new flow technology will result in a 10 to 15 reduction in the amount of energy consumed. The new generation of shrink tunnels can also be heated by gas instead of using classic electric heating. In comparison to electric heating, gas heating can reduce energy costs by up to 50. The newly developed khs shrink packer manipulating unit promises to provide even better pack stability for shrink film packs by wrapping containers in shrink film without the formation of shrinkage holes.
