Water- and oil-circulating temperature-control systems for standard and high-temperature applications to 650 F. Portable and central chilling systems from 5 to 200 tons. Chillers have compressor and control technology to match application. Cooling towers, water reservoir and pumping systems, water filtration and treatment equipment available.
Line of compact temperature control units with 9 and 12 kw heaters and pumps from 0.75 to 5 hp. Many models feature simplified internal cast or nonferrous fluid circuit with 40% fewer connections and 80% fewer mechanical parts than conventional designs. Simplified design provides balanced flow with lower pressure drop. Most of the company's temperature control units feature the M2B+ microprocessor control. Units also feature NEMA 12 electrics and meet new NEC electrical standards.
Water-temperature control units provide water supply temperature to 300 F. Heaters available in sizes to 48 kw; pumps from 0.75 to 7.5 hp. Single-, dual- and three-zone units can be supplied with common power and water supply connections. Nonferrous construction and a variety of control and computer-interface options available.
Metal cooling towers from 10 to 632 tons and fiberglass units from 50 to 200 tons. Equipment, chemicals, and testing programs offered.
The new GC Series central chiller from ACS, Schaumburg, Ill. (parent of AEC, Sterling, and Colortronic North America), has modules that range from 20 to 60 tons, allowing processor to add cooling capacity as the need arises, up to 300 tons.
At least 16 companies introduced new dryers at the big show in Chicago. The new models span a range of drying technologies, but most sport features that save space and cost and make the dryers simpler and more reliable.
If you never paid much attention to what kind of refrigerant is circulating inside your plastics chillers, it may be time you did.
At the NPE 2009 show in Chicago, half a dozen exhibitors showed new cooling equipment that emphasized improved performance at about the same or lower cost.
A new series of compressed-air venturi hopper loaders comes from ACS Group.
A continuous loss-in-weight feeding system and a gravimetric additive feeder are new from ACS Group, New Berlin, Wis.
Ability to be reconfigured for changing needs is one major design concept behind the new T500 Series central granulators from ACS Group, Schaumburg, Ill., parent of the AEC/Nelmor, Cumberland, Sterling, and Colortronic brands, all of which will offer the new models.
Smaller footprint, energy savings, and enhanced control (including a handheld pendant) are some of the new features of the first “green” chiller from ACS Group, New Berlin, Wis.
A line of high-speed, three-axis servo robots for small machines is new from Sterling Inc., New Berlin, Wis.
A new sprue picker that is lightweight, compact, and designed for presses from 22 to 165 tons comes from Harmo of Japan, represented here by AEC, Schaumburg, Ill., and sister company Sterling, New Berlin, Wis.
A new servo-wrist gripper that can transform a standard top-entry traversing robot into a six-axis model was introduced at K 2007 by Harmo of Japan, represented here by AEC, Schaumburg Ill., and Sterling, New Berlin, Wis.
A new Windows-based robot controller that can also control up to 31 auxiliary devices is new from Harmo of Japan, represented here by AEC, Wood Dale, Ill., and Sterling, New Berlin, Wis.
Is one type of resin dryer faster or more energy-efficient than another? That question prompts competing claims from suppliers—but very little concrete data. When one vendor performed controlled tests to get some answers, its results, published here for the first time, prompted further debate about the difficulties of making valid comparisons and the many complex issues involved in dryer selection.
At NPE in Chicago, chillers and TCUs were put on a lean energy diet and redesigned for greater durability. Suppliers also added features while taking out cost.
NPE 2006 held no revolutionary changes in dryers, blenders, feeders, loaders, or conveying controls, but widely adopted improvements make the newest models easier to use and maintain—and easier on the budget, too.
Injection molding robots introduced at NPE pushed the work envelope for speed, reach, payload capacity, ease of programming, and ability to handle more sophisticated tasks.
Most of the news at the show is in fluid-circulating mold-temperature-control systems.
Dryers, feeders, blenders, loaders, metal detectors, level sensors, mechanical and pneumatic conveyors, silos, bins, pumps, filters, valves, box fillers, bag dumpers, and materials-handling control systems constitute one of the biggest categories of products on display at NPE.
Recycling and reclamation are once again hot technologies—this time because of high resin prices.
Recent trends to-ward multi-material molding, hard/soft overmolding, and dual-durometer coextrusion create growing volumes of scrap that is difficult or impossible to reuse.
