The KST 80A-712 with Steam Venting Package is a tunnel system featuring stainless dual-wall construction. It is compatible with a wide range of containers, including those challenging to shrink consistently. The dual-zone system features five rows of steam distribution tubes on each side. Each row is externally adjustable for steam volume, flow and rotary position, so adjustments can be made without waiting for the tunnel to cool. A proprietary nozzle positioner directs steam during the shrinking process, optimizing steam resources and keeping utility costs low. Company precisely regulates steam flow in five distinct ways: step-down regulators, condensate traps, steam filtering, a proprietary steam valve and electronic regulation.
