Used AEC-Whitlock Equipment Sold by Meadoworks

AEC, originally known as Application Engineering Company, was established in 1957 in Schaumburg, Illinois, entering the market with process cooling equipment before expanding into a full line of plastics auxiliary systems. Over the following decades the company grew both organically and through a series of acquisitions, most notably absorbing Whitlock, a respected name in resin conveying and drying, whose expertise was folded into the broader AEC product portfolio. The combined AEC-Whitlock identity became widely recognized across the plastics processing industry for drying and material handling solutions.

The AEC-Whitlock product line centers on two areas that buyers most frequently seek on the used market: water temperature control units and resin dryers. The TrueTemp TCU Series water temperature control units deliver precise, automatic temperature control for continuous production applications, covering a wide range of water temperatures. On the drying side, AEC-Whitlock offers multiple technologies including the HA Series hot air dryers for non-hygroscopic materials, the WD Series dehumidifying dryers for hygroscopic resins requiring very low dew-point air, the AD Series desiccant wheel dryers, the compact ASD Series cabinet dryers, and large-capacity ADL Series and CDS Series central drying systems. The HA Series alone spans from 60 to 1500 CFM airflow, making it suitable for everything from single-machine cells to plant-wide installations.

AEC-Whitlock equipment serves a broad range of end markets, with plastics injection molding and extrusion at the core. Beyond plastics, the temperature control and drying product lines also find application in food processing, pharmaceutical manufacturing, chemical processing, and printing. The equipment is engineered to support high-throughput, continuous-production environments where consistent resin moisture levels and stable mold temperatures are critical to part quality.

Buyers seeking used AEC-Whitlock dryers and temperature control units are drawn to the brand for its reputation for rugged, long-service-life construction and the wide availability of OEM replacement parts through the ACS Group's global service network. The straightforward mechanical design of the TCU and HA Series equipment makes maintenance accessible for in-house technicians, keeping downtime low. Strong resale values and a large installed base mean that used AEC-Whitlock machines are easy to source, integrate, and support, making them a practical choice for processors looking to expand capacity or replace aging auxiliary equipment without the lead times of new machinery.
