1. High-Efficiency Heat Exchange：Adopting spiral or plate heat exchange structure with heat transfer coefficient ≥2000 W/(m²·℃)，30% more efficient than traditional heat exchangers，suitable for high-efficiency marine waste heat recovery.
2.Marine Corrosion Resistance：Heat exchange surface made of Hastelloy or 316L stainless steel, resistant to seawater and marine exhaust condensate corrosion，service life ≥10 years.
3. Vibration-Resistant Design：Reinforced shell with elastic connection of internal components，able to withstand vibration (vibration acceleration ≤5 g) and sway (±45°) during marine navigation.
4. Compact and Energy-Saving：40% smaller in volume than traditional heat exchangers，saving marine engine room space,no moving parts and low operating energy consumption，meeting marine energy-saving requirements.
5. Easy Cleaning and Maintenance：Adopting detachable heat exchange core for quick cleaning by crew during port calls，avoiding scaling that affects heat exchange efficiency (e.g., scaling is prone to occur in marine seawater heat exchange).
