The technology from Addex of the USA is an advancement on 40-year-old technology, only better

ADDEX Inc, a leading global supplier of auto-profile and other related cooling systems for blown film lines, has launched the Intensive Cooling Experience (ICE) system, a unique cooling technology that can increase output by 40-60% for blown film extrusion lines.

The ICE system in fact adapts 40-year-old cooling technology and is a major improvement over conventional air ring technology. The new bubble cooling technology will be shown in Hall 17 stand C37.

The new patent pending ICE™ Element design consists of a series of cooling rings arranged in a stackable configuration to achieve higher output rates. Each of these air rings direct divergent air flow along the bubble, both upward and downward from each stacked cooling element, to provide high film-holding forces and peak cooling efficiency. The high-performance divergent cooling elements are assembled using simple spacer pipes that also provide a common feed of cooling air to each cooling element level. The stack mounts directly to the top of the die, forming a short stack topped with an Addex dual-flow air ring.

The system includes an enclosure which fully surrounds the stack, replacing the surrounding atmosphere with a highly stable controllable ambient pressure. Each enclosure includes variable speed, low-pressure fans to operationally set the pressure differential between the inside and outside of the bubble. The system includes easy-to-interpret operator feedback and adjustment for optimizing the stability and cooling efficiency of this enclosed, stacked cooling system.

The ICE system applies to all polyolefin and barrier blown film processes. It is now commercially available worldwide, with units already sold in both North America and Europe.
