Finned-tube heat exchangers
Finned-tube heat exchangers are the ideal choice when the process air is contaminated, operating temperatures are very high, or when special materials or configurations are required.
Thanks to their mechanical robustness and great design flexibility, they are used in a wide range of industrial applications: process plants, furnaces and drying lines, heat recovery from high-temperature flue gases, cryogenic applications, and air-to-air systems operating under severe conditions.
Versions are available with wrapped, interlocked, or continuously welded fins, each designed to maximize strength, reliability, and performance under the most critical conditions.
