USED WITTE 42? X 12?

Manufacturer Information
Witte Company
Witte manufactures industrial fluid bed processing and vibrating equipment used for drying, cooling, heating, classifying, and conditioning bulk solids. Fluid bed systems use controlled airflow combined with vibratory conveying to promote contact between process air and free-flowing granular material.
This Witte Model 42 x 12' system was previously used for PE pellets and is configured with a natural gas heating system, shaker drive, induction blower, temperature controls, ductwork, and exhaust components.
Description
Available for sale is a used Witte Model 42 x 12' PE Pellet Fluid Bed Cooler, Serial Number 5263, measuring approximately 45" wide x 12'10" long and currently set up for heat.
The system features a Siemens 3 HP shaker motor, Power Flame FD300 natural gas burner with RCP FD300 control box, induction blower, temperature regulators, tension-spring-supported shaker deck, and removable hood with safety chain. Fabricated induction ducting and a cylindrical exhaust hood are also included.
According to the supplied condition information, the screen is in great condition with no bends or clogs, and the shaker, motor, burner, blower, and temperature controls are functioning as intended. The shaker fluid was changed in January 2026.
The equipment was previously used for polyethylene (PE) pellets and may be suitable for heating, drying, conditioning, or cooling compatible plastic pellets and other free-flowing granular materials. Actual thermal performance and throughput will depend on the product, inlet condition, airflow, temperature, residence time, and system configuration.
