Spiral Tube Heat Exchangers
Spiral tube heat exchangers are the ideal choice when the process air is dirty, 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 across a wide range of industrial applications: process plants, ovens and drying lines, high-temperature flue gas heat recovery, cryogenic applications, and severe-duty air-to-air systems.
Versions with wrapped, interlocked, or continuously welded fins are available, each designed to maximize strength, reliability, and performance under the most critical conditions.
