The new KSA-70-712 is a high quality steam tunnel that incorporates many of the engineering features which have distinguished PDC's larger capacity tunnels and labeling systems. It is ideal for applications that demand precise label registration and shape conformance. It is also an excellent option for packages involving contents that are flammable or under pressure. The KSA-70-712 is a compact, 70" long system that precisely focuses steam onto specific points of the shrink-sleeved packages. The tunnel has symmetrical steam distribution tubes on each side, and each pair of tubes is externally adjustable for steam volume, flow and rotary nozzle position. Adjustments can be made "in real time," without wasting time - and energy - waiting for the tunnel to cool down.
A thermostatically controlled steam chamber, available as an option, generates the most energy-efficient steam system possible. Unlike straight pressure systems, which waste energy by pumping large volumes of steam into the tunnel without electronic regulation, PDC's unique control system uses only the steam required to maintain chamber temperatures and provide optimal shrink quality.
Opening dimensions for the KSA-70 are 12" high X 7" wide. The KSA-70-712 provides precise label registration, distortion-free graphics, and exceptional conformance to the container shape. The system virtually eliminates the risk of container distortion. PVC, PETG, OPS and PLA films, in gauges as thin as 40 microns, are all compatible.
The KSA-70 can process up to 200 cpm, depending on container size and shape. Containers can be virtually any geometry, including round, oval and square, and can be filled or empty. Where bottles are labeled empty, a heated shroud is available to prevent condensate from dripping into empty containers. Other optional features include an electronic temperature regulator, a powered steam venting manifold with dampers, and a condensate diverter package.
Several levels of steam filtering provide up to culinary grade steam, while also removing impurities. PDC can also provide a range of steam boilers optimally sized to customer requirements.
The KSA-70 steam tunnel is an excellent choice for end-use packagers. It is ideal as a stand-alone system, or as a supplemental "finishing zone" for a dual-zone tunnel. It is also highly efficient as a pre or post-shrink module. The KSA-70 is equally well-suited to contract packers who need a highly reliable and very economical steam shrink tunnel.
