Atlas Copco GA132–160W WUXI Cooler Kit Replacement – 2906100100

The Atlas Copco 2906100100 is a cooler service kit designed for the cooling system of GA132–160W compressors. The cooler removes heat generated during compression and oil circulation, helping maintain the compressor’s operating temperature within the required range.

The kit includes replacement O-rings and sealing components used when servicing the cooler. The Atlas Copco parts list identifies multiple O-rings as components of 2906 1001 00.

Working Process

1. Compression – Air is compressed inside the screw element, generating heat.
2. Oil Circulation – Compressor oil circulates through the system and absorbs heat.
3. Heat Transfer – The hot oil/air stream passes through the cooler.
4. Cooling – Heat is transferred from the compressor medium to the cooling system.
5. Temperature Control – Cooled oil returns to the compressor circuit at a controlled temperature.
6. Seal Maintenance – During cooler servicing, worn O-rings are replaced using the components supplied with 2906100100.
7. Leak Prevention – New sealing components help prevent oil or coolant leakage.
8. Continuous Operation – The serviced cooler maintains effective heat removal during compressor operation.

Kit Components

The Atlas Copco parts documentation identifies these sealing components for 2906 1001 00:

Main Functions

• Supports GA132–160W cooler maintenance.
• Provides replacement cooler sealing components.
• Helps prevent oil/coolant leakage.
• Maintains proper cooler sealing.
• Supports effective heat transfer.
• Helps maintain correct compressor operating temperature.
• Reduces the risk of overheating caused by cooler-related problems.

Possible Failure Symptoms

A deteriorated cooler or cooler seals may contribute to:

• Increased oil temperature.

• Increased compressor energy consumption.
• Reduced compressor performance.

Maintenance Procedure

1. Shut down the compressor according to the applicable Atlas Copco service procedure.
2. Isolate the electrical supply.
3. Allow the compressor to cool completely.
4. Depressurize the relevant air and oil circuits.
5. Isolate and drain the applicable cooling/oil circuit.
6. Remove the cooler connections.
7. Inspect the cooler and sealing surfaces.
8. Remove old O-rings.
9. Clean all mating surfaces.
10. Install the replacement O-rings supplied with 2906100100.
11. Reassemble the cooler connections.
12. Tighten all connections according to Atlas Copco specifications.
13. Restore the oil/cooling circuit.
14. Restart the compressor.
15. Check for leakage.
16. Monitor oil temperature and compressor operating temperature.
17. Confirm normal cooling performance.
