Seawater-Resistant DWBE-SW Stainless Steel Fin Oil/Water Cooler for Marine Use

URL: /seawater-oil-cooler-dwbe-sw-stainless

Product Summary

The DEO DWBE-SW is a customized anti-corrosion version of the fin-type shell-and-tube oil/water cooler, specifically designed for seawater and heavily polluted water. Built with 304 stainless steel fins and tubes, and optional stainless steel shell, it resists corrosion in harsh marine environments. The expand tube process maintains high heat transfer efficiency while ensuring long-term durability.

Key Selling Points

• Seawater Corrosion Resistance: 304 stainless steel fins & tubes (optional shell) withstand saltwater and chemical attack – extends equipment life in marine applications.
• Reliable Heat Transfer: Expand tube process bonds fins to tubes for efficient heat exchange even in high-fouling water.
• Low Maintenance: Detachable end cover enables easy cleaning of sediment and marine growth – reduces downtime.
• Adaptable to Dirty Water: Anti-corrosion structure handles seawater, heavily polluted water, and cooling water with impurities.
• Space-Saving: Compact shell-and-tube layout fits tight engine rooms and equipment compartments.
