Atlas Copco Oil Cooler Kit, Reliance Replacement – 2910563601

The Atlas Copco 2910563601 is an Oil Cooler Kit for Reliance (RE) compressor applications. The oil cooler is responsible for removing heat from the compressor oil generated during operation.

During compression, the oil becomes hot as it absorbs heat from the compressor element and associated components. The hot oil flows through the oil cooler, where heat is transferred to the cooling medium. The cooled oil then returns to the compressor oil circuit, helping maintain the required operating temperature.

Working Process

1. Oil Circulation – Compressor oil continuously circulates through the lubrication/cooling circuit.
2. Heat Absorption – The oil absorbs heat generated during compressor operation.
3. Hot Oil Flow – Heated oil enters the oil cooler.
4. Heat Transfer – Heat moves from the oil through the cooler’s heat-transfer surfaces to the cooling medium.
5. Oil Cooling – The oil temperature is reduced.
6. Cooled Oil Return – The cooled oil returns to the compressor circuit.
7. Continuous Cycle – This process continues while the compressor is operating.

Main Functions

• Removes heat from compressor oil.
• Maintains suitable oil temperature.
• Supports effective lubrication and cooling.
• Helps protect compressor components from excessive temperature.
• Maintains reliable compressor operation.
• Restores cooling performance during oil-cooler service.

Possible Failure Symptoms

A contaminated, blocked or damaged oil cooler can cause:

• High oil temperature.
• High compressor discharge temperature.
• Reduced cooling efficiency.
• Increased energy consumption.
• Temperature alarms.
• Compressor thermal shutdown.
• Oil leakage.
• Reduced compressor reliability.

Maintenance Process

1. Shut down the compressor according to the applicable Atlas Copco service procedure.
2. Isolate electrical and relevant cooling systems.
3. Depressurize the compressor.
4. Allow the oil and cooler to cool.
5. Drain/isolate the applicable oil circuit.
6. Remove the existing oil cooler and associated connections.
7. Inspect for contamination, corrosion and leakage.
8. Clean the mating surfaces.
9. Install the components supplied with 2910563601.
10. Reconnect the oil and cooling circuits.
11. Restore the system.
12. Restart the compressor.
13. Check for oil/coolant leakage.
14. Monitor oil and discharge temperatures.
