- Hydrophilic aluminum: Good for clean marine ventilation, low cost. Stainless steel (304/316L): Resists salt and many chemicals; heavier and pricier. Epoxy / phenolic coated aluminum: Adds a barrier for acidic exhaust. Titanium: For extreme seawater or chloride exposure (premium).
- Use drained, washable cores to remove salt and debris. Avoid crevices where chloride can pool. Specify marine-grade fasteners and frames. Plan for periodic fresh-water rinsing in offshore service.

Plate and heat-pipe cores with stainless or coated plates are the most durable; rotary wheels need careful desiccant and seal material selection.
Ships, offshore platforms, and chemical plants expose heat exchangers to salt spray, high humidity, and aggressive gases. In these corrosive environments, material selection is as important as thermal design.

Is aluminum safe at sea?
Bare aluminum corrodes in chloride environments. Coated aluminum or stainless is strongly advised for marine duty.
Which technology survives best?
Plate and heat-pipe cores with stainless or coated plates are the most durable; rotary wheels need careful desiccant and seal material selection.
