Atlas Copco Oil Cooler Kit Replacement – 2906013000

The Atlas Copco 2906013000 Oil Cooler Kit is used to service the oil-cooling circuit of applicable ZA/ZR5–6 oil-free compressor systems. The cooler transfers heat away from the oil/cooling circuit, helping maintain the required operating temperature and lubrication performance. Parts references specifically associate 2906-0130-00 with ZA/ZR5–6.

Working Process

1. Heat Generation – Compressor operation generates heat that must be controlled.
2. Hot Oil/Cooling Medium Flow – The heated medium enters the oil-cooler circuit.
3. Heat Transfer – Heat passes through the cooler’s heat-transfer surfaces.
4. Cooling – The cooling medium removes heat from the oil/circuit.
5. Temperature Reduction – The oil temperature is brought back toward its required operating range.
6. Return Flow – Cooled oil/cooling medium returns to the relevant compressor circuit.
7. Continuous Operation – The cycle continues while the compressor is operating.

Main Functions

• Maintains proper oil/circuit temperature.
• Removes excess heat.
• Supports reliable compressor operation.
• Helps prevent overheating.
• Maintains effective lubrication performance where applicable.
• Restores sealing and cooler connections during service.
• Helps reduce leakage from the cooler assembly.

6. Remove the cooler service components.
7. Inspect the cooler for corrosion, contamination and leakage.
8. Clean the mating surfaces.
9. Replace the seals, O-rings and gaskets using 2906013000.
10. Ensure all sealing components are correctly seated.
11. Reassemble the cooler.
12. Restore the circuit and refill where required.
13. Restart the compressor.
14. Check for leakage.
15. Monitor oil/cooling temperature and verify normal operation.
