Cooling Bulk Solids Using Air
Bulk solids pass slowly downward between a series of heat exchange elements.
Air (or gases), acting as the heat transfer medium, cools the material indirectly by conduction.
A mass flow discharge feeder creates uniform product velocity and regulates the product flow.
Bulk solids pass through the vertical heater by gravity.

The Advantages of Indirect Heat Exchange
Indirect air/gas heat exchange provides many advantages. The air used for cooling the bulk solids never comes into direct contact with the product, which preserves the integrity of the product and eliminates the need to treat the incoming or outgoing air. It also makes energy recovery while cooling or heating a viable option.
Guaranteed Thermal Performance
Solex uses its proprietary thermal modeling software, ThermaPro, to accurately predict product temperature profiles of the bulk solid material at each point through the heat exchanger. The result is guaranteed thermal performance.
Suitable Applications for Indirect Air-Cooling
When the incoming temperature of the bulk solids is from 200°C to 2000°C and when the required discharge temperature is 50°C (or greater) of ambient air temperature, indirect air-cooling is a possible option.
Green Technology for Cooling Bulk Solids
The Solex air-cooled heat exchanger can capture valuable heat while cooling bulk solid materials, making this recovered energy available as hot air for use elsewhere in your facility.
