Oil Cooler Manufacturer in Morocco

Types of Hydraulic Oil Coolers

1. Air-Cooled (Fin-Fan Coolers)
   1. Uses ambient air (with fans) to cool the oil.
   1. Common in mobile equipment (excavators, cranes) and industrial systems with good airflow.
2. Water-Cooled (Shell & Tube / Plate Coolers)
   1. Uses cooling water (from a plant cooling system or chiller) to extract heat.
   1. More efficient in high-heat applications (steel mills, injection moulding machines).
3. Oil-to-Oil Coolers
   1. Transfers heat from hydraulic oil to another cooler oil circuit (less common).

When is a Hydraulic Oil Cooler Necessary?

• High-pressure or high-cycle hydraulic systems.
• Continuous operation (e.g., industrial presses, plastic injection machines).
• Environments with high ambient temperatures.
• Systems using sensitive components (servo valves, precision actuators).
• Signs Your Hydraulic System Needs a Cooler
• Oil temperature exceeds 70°C (158°F) regularly.
• Frequent oil changes due to degradation.
• Reduced system efficiency (slow operation, overheating pumps).
• Increased noise or leaks from seals/hoses.
