Safety Double-Tube Heat Exchangers
Safety double-tube heat exchangers are designed for critical applications where leaks or cross-contamination are not acceptable.
Thanks to their two-tube concentric configuration, these exchangers ensure complete fluid containment in the event of failure of the inner tube, allowing the system to remain operational until maintenance can be scheduled.
They are used for cooling engines, transformers, electrical equipment, and industrial processes where safety and reliability are essential requirements.
