Counter-current cooler for the continuous cooling of pelleted or free-flowing bulk materials. Gentle cooling to ambient temperature using the proven counter-current principle. Robust industrial design, configured for the specific application and project.
Short description
Counter-current coolers are designed for the continuous and gentle cooling of pelleted or free-flowing bulk materials. The proven counter-current principle efficiently cools the product to ambient temperature while removing excess moisture.
Their design allows reliable integration into different process lines and applications.

Discharge system: pneumatic
Technical functional description
The hot product is fed into the upper section of the cooler and moves down through the cooling chamber by gravity. At the same time, ambient air is introduced into the cooler from below or from the side and flows through the product bed in the opposite direction.
This arrangement provides uniform heat and mass transfer, ensuring even product cooling with low mechanical stress. The warmed exhaust air is discharged in a controlled manner, while the cooled product is discharged through a regulated discharge system.
The cooler is designed according to the product type, throughput, temperature requirements and installation conditions.
