High-Efficiency Oil Cooling For Industrial And Marine Applications
The Water/Oil Cooler Type is a compact and robust heat exchanger designed for efficient removal of heat from circulating oil systems. With a cooling capacity of 74 kW and a high oil flow capability, this cooler is well suited for demanding industrial machinery as well as marine environments where stable oil temperature control is essential for equipment reliability and longevity.
Key Technical Specifications
Cooler type: Water/Oil Heat Exchanger
Cooling capacity: 74 kW
Oil flow rate: 390 L/min
Required cooling water flow: 22 m³/h
Cooling water temperature (inlet / outlet): 35 °C / 38 °C
Version: Sweet water and sea water resistant
These parameters indicate a design optimized for high thermal loads with moderate cooling water temperature rise, ensuring efficient heat transfer without excessive water consumption.
Performance Characteristics
The cooler operates by transferring heat from hot circulating oil to cooling water through an internal heat exchange surface. With a 3 °C water temperature increase, the unit achieves stable and controlled oil cooling while maintaining efficient energy utilization.
The high allowable oil flow rate of 390 L/min makes this cooler suitable for systems with large oil circulation volumes, such as hydraulic power units, lubrication systems, and gearboxes.
Construction and Materials
The sweet and sea water resistant version indicates that the cooler is manufactured using corrosion-resistant materials or protective coatings suitable for:
Freshwater industrial cooling circuits
Seawater cooling systems in marine or offshore installations
This makes the P20 2P-L-800 particularly suitable for harsh operating environments where corrosion resistance and long service life are critical.
Typical Applications
Marine propulsion and auxiliary systems
Offshore platforms and coastal installations
Hydraulic systems in heavy industry
Gearbox and bearing lubrication oil cooling
Power generation equipment
Industrial compressors and pumps
Operational Benefits
Stable oil temperature control, reducing wear and extending equipment life
High cooling efficiency relative to compact size
Low maintenance requirements due to water-side cooling
Adaptability to seawater applications, reducing the need for intermediate cooling loops
Installation and Maintenance Considerations
Adequate cooling water flow (22 m³/h) must be ensured for rated performance
Water quality should be controlled to minimize fouling and scaling
Periodic inspection and cleaning of the heat exchange surfaces will maintain long-term efficiency
Conclusion
The Water/Oil Cooler Type is a reliable and efficient solution for oil cooling in both industrial and marine environments. With its 74 kW cooling capacity, high oil flow handling, and resistance to sweet and sea water, it delivers dependable thermal performance under demanding operating conditions.
