Used Thoreson McCosh Equipment Sold by Meadoworks

Thoreson McCosh was founded in 1947 in Troy, Michigan, and quickly established itself as a pioneer in dehumidifying thermoplastic resin materials. The company was among the first to develop a machine-mounted desiccant dryer, replacing the earlier practice of oven-drying resin and manually transporting it to processing machines. Over more than seven decades it grew into one of the plastics auxiliary equipment industry's most recognized names, eventually being acquired by Advanced Blending Solutions (ABS) of Wallace, Michigan in June 2020, which continued manufacturing the Thoreson McCosh product lines and invested in updated controls and energy-efficiency improvements.

The flagship product lines are the TD Series Thermal-D desiccant dryers and the DVL Series portable dryers. TD Series units are closed-loop, valveless desiccant dryers engineered to maintain a process dew point of -40°F and are available across a wide capacity range, from compact bench-top models through large central units rated at hundreds of pounds per hour. The DVL Series combines drying and vacuum loading in a self-contained, cart-mounted cell suited to smaller throughput requirements. On the conveying side, Thoreson McCosh produced the MK-Series and Guardian vacuum pumps, which move resin from gaylords, bags, or bulk storage to machine throats and drying hoppers, with configurations ranging from single-station portable units to multi-pump central systems.

Thoreson McCosh equipment serves plastics processors across injection molding, blow molding, extrusion, blown film, and pipe and profile applications. End markets include packaging, automotive components, medical device manufacturing, consumer goods, and wire and cable production — essentially any industry that processes hygroscopic thermoplastic resins and requires consistent, moisture-free material at the machine.

Used Thoreson McCosh dryers and vacuum pumps remain highly sought after because the equipment was built to industrial-grade standards with straightforward mechanical designs that are easy to service and maintain. Desiccant beds are field-replaceable, spare parts have remained available, and the closed-loop TD Series architecture means units routinely deliver reliable performance after 20 or 30 years in production environments. The combination of proven longevity, wide capacity coverage, and relatively simple controls makes used Thoreson McCosh auxiliary equipment an economical choice for processors looking to expand drying or conveying capacity without the lead time or cost of new equipment.
