High-Efficiency DWBE-408 Copper Fin Oil/Water Cooler for Hydraulic Systems
URL: /oil-water-cooler-dwbe-408-copper
Product Summary
The DEO DWBE-408 is a fin-type shell-and-tube oil/water cooler designed for efficient heat dissipation in hydraulic and lubrication systems. With a compact footprint and expand tube process that tightly bonds copper fins to high-purity copper tubes, it delivers high heat transfer efficiency. Standard model features copper fins and tubes with carbon steel shell, suitable for clean cooling water.
Key Selling Points
- Enhanced Heat Transfer: Copper fin-tube structure provides large heat exchange surface (1.3 m²) – maximizes cooling capacity in compact size.
- Low Oil Flow Resistance: Large-diameter oil ports reduce pressure drop, minimizing energy loss in hydraulic circuits.
- Easy Maintenance: Detachable end cover allows quick internal cleaning and descaling – reduces downtime.
- Durable Construction: High-purity copper tubes and carbon steel shell with anti-rust coating ensure long service life under standard conditions.
- Flexible Integration: G1 thread ports standard; SAE flanges optional – easy to connect to existing systems.
