Cross-flow Heat Exchanger CHE
Efficient Degassing & Drying
Compact and highly efficient cross-flow heat exchanger for degassing processes and drying tasks
The patent-protected CHE cross-flow heat exchanger is a central component of the Fresh-TEC® process developed by Zeppelin Systems and was designed for continuous industrial operation. It is used to neutralize odors in recycled granules (regranulates) and to reduce odors during the production of plastic compounds containing additives and fillers. Furthermore, as part of the Fresh-TEC® process, the CHE enables highly efficient surface drying of granular bulk materials, thereby contributing significantly to improved quality, process reliability, and cost-effectiveness in plastics processing.
Advantages
Special Highlights
A key advantage of the system is the direct heat transfer via a gas flow that crosses the flow direction of the bulk material. This cross-flow allows higher gas velocities and therefore higher energy exchange. Heat transfer occurs directly at the phase boundaries of all granules, resulting in very uniform heating and reliably preventing the formation of hot spots.
Precise Temperature Control
Precise temperature control of the bulk material up to a maximum of 120 °C (standard); higher temperatures available upon request as a special option
Easy-to-clean design
Quick and easy cleaning thanks to the modular design and stable base frame
Customized Process Adaptation
Customized design based on bulk material mass flow, bulk material properties, and other relevant process parameters
Reliable Product Protection
A closed system for protecting bulk materials from external environmental factors
Durability & Operational Reliability
High-quality materials and durable, reliable components for maximum uptime and service life
A Breath of Fresh Air for Plastic Recycling
How can plastic waste be processed so that it can be reused in a variety of high-quality applications? Odors and contaminants often significantly limit the use of recycled materials and regranulates. Zeppelin Systems’ continuous-operation Fresh-TEC® deodorization systems solve this problem by removing volatile organic compounds (VOCs) from the temperature-controlled recycled material through targeted air purging. This significantly enhances the value of plastic recyclates, allowing them to be reliably used in a wide range of applications.
Our Benefits for the Industry
The CHE cross-flow heat exchanger combines high energy efficiency, reliable process safety, and gentle bulk material handling in a compact system. This makes it possible to carry out degassing and drying processes particularly efficiently and cost-effectively:
Areas of application
High-quality recycled materials for a wide range of industries
In numerous industries, odors and volatile organic compounds (VOCs) pose a major challenge, particularly when the use of recycled plastics in high-quality applications is to be increased. This is precisely where Zeppelin Systems’ Fresh-TEC® deodorization systems come into play. Within this process, the CHE cross-flow heat exchanger plays a crucial role by ensuring precise temperature control of the bulk material before and after the continuous degassing processes.
Furthermore, the CHE cross-flow heat exchanger is ideally suited for drying applications in which granular bulk materials must be efficiently and gently dried to remove surface moisture. Thanks to its high energy efficiency and uniform heat transfer, the CHE supports stable processes and consistent product quality across a wide range of applications.
