Indirect cooling drums for process heat recovery
Optimize your production by effectively cooling hot solids while recapturing valuable heat energy, ensuring reduced energy costs and enhanced sustainability throughout your processes.

Cools and Recovers Heat from Hot Solids
The Indirect Cooling Drums from Allgaier Process Technology offer robust solutions for cooling hot solids while effectively recovering thermal energy. Ideal for industries including mining, chemicals, and waste processing, these drums utilize an indirect rotary design where hot material is cooled by air passing through separated chambers. This eliminates direct contact, enhancing the efficiency of heat transfer and enabling energy conservation. Suited for applications such as titanium pigment production and gypsum plasterboard manufacturing, the equipment handles diverse materials from powders to granules.
These cooling drums are continuous-operation machines, ensuring consistent throughput and integrating seamlessly into existing lines. The design minimizes energy consumption by utilizing preheated, dry exhaust air, reducing both operational costs and environmental impact. Constructed with durable materials, the drums are engineered for long-term performance and minimal maintenance. Customization options are available to adapt the drums for specific processing needs, supported by Allgaier’s engineering expertise.
