KST 55-712 Features
The KST 55-712 is a single-zone system with five rows of steam distribution tubes on both sides of each zone for a total of 10 steam runs. There is a pre-shrink zone at the entry to the tunnel to anchor sleeves at the base of containers. Each run is externally adjustable for steam flow and rotary position so adjustments can be made without waiting for the tunnel to cool.
Steam regulation is key to consistency, so PDC precisely regulates steam flow in five distinct ways: step-down regulators, condensate traps, steam filtering, a proprietary steam valve and optional electronic regulation. Each tunnel includes a stainless-steel vent manifold with adjustable dampers to closely regulate the steam exhaust drawn from the tunnel.
The electronic regulator developed by PDC monitors tunnel temperatures in real time and makes continuous adjustments in steam release to compensate for the “thermal loads” of incoming product. This is particularly useful when the system is running full or cold containers.
PVC, PETG, OPS and PLA films, in gauges as thin as 30 microns, all shrink uniformly in the KST 55 steam tunnel.
Built for a Variety of Containers
The KST 55-712 has stainless dual wall construction and opening dimensions of 7” in width x 12” in height. It is compatible with a wide range of containers for speeds up to 100 containers per minute. Containers can be filled or empty, and virtually any shape, including oval or square.
The system mounts over existing conveyors, or PDC can provide conveyors specifically constructed for use in steam. Options include a heated shroud that shields the top of the empty containers inside the tunnel, a condensate diverter package, a culinary grade steam filter that purifies incoming steam, and a vent blower stand with a variable frequency drive. Like all PDC steam tunnels, the KST 55 is manufactured in the USA using high quality stainless steel and standard components that are readily available.
PDC manufactures shrink tunnels for every shrink sleeving application, including convection hot air and radiant infrared systems, single and multiple-zone tunnels, and pre and post shrink systems. Tunnels can be fully integrated with application machinery, or operate independently.
PDC International Corp. provides shrink sleeve labeling and tamper evident neck banding technology for packaging in the food, beverage, personal care and pharmaceutical industries.
