CHICAGO — AEC Inc. of Wood Dale, Ill., introduced a new line of stainless-steel hoppers and hopper loaders, as well as a line of portable chillers, at Plastics USA, held Oct. 6-8 in Chicago.
The SR-series vacuum receivers and hopper loaders are available in five sizes of 0.1-1.6 cubic feet. The corrosion-free, stainless-steel construction is standard for lower maintenance and faster cleaning, according to AEC.
The vacuum receivers run from $450-$800 and the hopper loaders cost $1,000-$1,400.
The hoppers can be purchased as a standard hopper loader, as a sight-glass hopper loader or as a standard or sight-glass-type vacuum receiver for use in a central conveying system. The hoppers also were designed in modular fashion, so that the tube stubs, hopper bodies, quick clamps and motor assemblies are interchangeable.
Backward integration is important for AEC customers, said Lou Zavala, AEC vice president of marketing and engineering. The hoppers were developed to be compatible with the existing and previous models of AEC Whitlock conveying and drying equipment.
``Processors are expecting more from their basic loading and conveying equipment,'' Zavala said. ``This new product meets their new, more demanding requirements.''
The PS-series portable chillers range in capacity from 5-15 horsepower. The new chillers feature scroll compressors, brazed plate evaporators and an off-the-shelf auto-tuning control. They are available in air- and water-cooled versions.
The 5- and 71/2-ton machines cost $7,800-$10,000. In the next couple of weeks, 10- and 15-ton chillers also will be available, Zavala said.
The chillers have scroll-compressor technology previously unavailable in those sizes and capacities. That technology has become more popular in the past year, Zavala said, because AEC manufacturing engineers have solved complex-part geometry problems and were able to meet precise requirements.
Advantages to scroll compressors include smooth, quiet operation with as much as 15 percent higher energy efficiency. There are no valves, no compression losses and little heat transfer between suction and discharge gas, AEC said.
To manage AEC sales agents, customers and business prospects west of the Rocky Mountains, AEC has named Bill Oscar to the position of western area sales manager.
Oscar will be selling AEC's full integrated line of auxiliary equipment to injection molders and extruders, the firm announced.
Oscar, who last worked at Universal Dynamics of Woodbridge, Va., also will oversee equipment and parts inventory at AEC's distribution and service center in Southern California.
Meanwhile in the Midwest, AEC has a new representative for its extrusion customers in northern Illinois. CRG Systems now covers the extrusion end of the market's own sales agency, EESCO, and will continue to cover equipment sales to injection molders and other nonextrusion plastics processors in the region.
CRG domain includes systems design, installation and consulting services for extrusion firms in northern Illinois. It also provides controls consulting to U.S. and Canadian extruders.
In other AEC news, AEC/Nelmor of North Uxbridge, Mass., announced at the show that it has chosen Allen-Bradley Co. to supply starters and contactors for its size-reduction equipment, including shredders and granulators.
Nelmor said it began converting to Allen-Bradley 509 NEMA starters this month.
AEC is a leading manufacturer of conveying, drying, blending, chilling, automation and size-reduction equipment for the plastics industry.
AEC is owned by Harbor Group Ltd. of St. Louis.
