Heat exchangers handle viscous and high-fouling materials

The HRS Unicus heat exchanger can be scaled according to need by increasing the shell diameter and adding more interior tubes as required, from one tube up to 80; the tubes contain a stainless steel rod and come in a range of materials, such as Teflon and PEEK. The heat exchanger also includes a hydraulic cylinder and power pack, a stainless-steel scraping mechanism that is hydraulically moved back and forth within each interior tube and a separation chamber; in smaller units, a pneumatic cylinder can be supplied instead of a hydraulic unit. Standard models provide heat transfer areas from 0.7 to 10 m², while larger models up to 120 m² can be made according to specific requirements.
