SpiroSwirl™ Coil-in-Shell
High-Efficiency Helical Coil Heat Exchangers for Compact Thermal Systems
Tube Tech® SpiroSwirl™ Coil-in-Shell units feature precision-formed helical coils housed inside a robust shell, engineered to deliver superior heat transfer in compact footprints.
The swirling flow path increases turbulence, enhances thermal exchange, and minimizes fouling - making them ideal for high-performance heating, cooling, and process applications. These highly Efficient Liquid to Refrigerant Heat Exchangers can be used in any application where air or water must be heated or cooled.
