The Oil Cooler for Drive Gearbox System is a purpose-engineered heat-exchange unit designed to ensure stable lubrication oil temperature in high-duty gearbox applications. This cooler provides reliable and continuous thermal control for drive gearbox lubrication circuits operating under elevated temperatures and pressures.

Built with CuNi 90/10 (CuNi10) tube material, the cooler delivers exceptional corrosion resistance, mechanical durability, and long-term performance—particularly important in marine, offshore, and industrial environments where lubrication reliability directly affects gearbox lifespan.

Service

• Lubricating Oil Cooling
  The oil cooler maintains the viscosity, stability, and lubrication quality of gearbox oil by dissipating excess heat generated from mechanical friction within the drive gearbox.

Function

• Thermal Protection: Prevents oil breakdown at high temperature.

• Lubrication Stability: Ensures proper oil film thickness on gear surfaces.

• System Reliability: Protects bearings, gears, and seals from thermal stress.

• Continuous Operation: Allows the gearbox to operate safely under heavy loads and high-speed conditions.

Application (FFT / Application)

• Drive Gearbox Lubrication Oil System
  Used in continuous industrial gear drives, power transmission systems, marine propulsion gearboxes, offshore machinery, and heavy mechanical equipment.

Key Features

• Robust shell-and-tube / coiled-tube heat transfer design
  Ensures effective cooling even with high-viscosity lubrication oils.

• Corrosion-resistant CuNi 90/10 tube bundle
  Ideal for marine and offshore gearbox environments.

• High temperature capability (up to 150°C)
  Prevents thermal degradation of oil and ensures consistent gearbox performance.

• High design pressure (25 bar)
  Withstands demanding lubrication oil pressures without risk of deformation or leakage.

• Compact footprint (WT-LOK variant)
  Suitable for confined installations or retrofit upgrades.

The CuNi 90/10 Oil Cooler for Drive Gearbox Systems is engineered to meet demanding service conditions. Its durable construction and efficient heat-transfer performance make it a critical component in any heavy-duty gearbox lubrication oil system.
