Sectional cooler
A sectional cooler is a type of liquid cooled rotary drum cooler used for continuous processes in chemical engineering. Sectional coolers consist of a rotating cylinder ("drum" or "shell"), a drive unit and a support structure. At each end of the drum there are stationary chutes for material feed and outlet. Depending on the size of the cooler the drum is pivoted on a shaft running through its axis, or is supported on running treads or external ring gears. The interior of the drum consists of several wedge-shaped chambers arranged around a central hollow shaft.
