Atlas Copco Service Kit / Aftercooler Kit Replacement – 2910563500

The Atlas Copco 2910563500 is a service kit used for maintenance of the compressor cooling/aftercooler system. Parts catalogs identify it as a KIT, SERVICE, while another Atlas Copco parts listing identifies it as KIT-AFTER COOLER (K7).

The aftercooler reduces the temperature of compressed air after compression. During operation, compressed air becomes hot, and cooling it before it enters the downstream air system helps reduce thermal load and manage moisture condensation.

Working Process

1. Air Compression – The compressor compresses incoming atmospheric air.
2. Heat Generation – Compression increases the temperature of the compressed air.
3. Hot-Air Flow – The hot compressed air moves toward the aftercooler.
4. Heat Transfer – Heat is transferred from the compressed air through the cooler’s heat-transfer surfaces.
5. Air Cooling – The compressed-air temperature is reduced.
6. Moisture Condensation – Cooling can cause water vapor to condense.
7. Condensate Removal – The downstream moisture-management system removes the condensate.
8. Cooled-Air Delivery – The cooled compressed air proceeds to the air receiver or downstream equipment.

Main Functions

• Supports aftercooler servicing.
• Helps restore effective heat transfer.
• Maintains proper compressed-air temperature.
• Helps prevent air/cooling-system leakage.
• Supports condensate management.
• Helps maintain compressor efficiency.
• Reduces the risk of excessive operating temperatures.

Typical Service Components

Because 2910563500 is cataloged as a service kit, the exact contents can depend on the applicable compressor configuration. Parts references confirm the part as 2910 5635 00 and identify it as a service kit.

Possible Failure / Poor-Cooling Symptoms

A deteriorated aftercooler or service components can contribute to:

• High compressed-air temperature.
• Reduced cooling performance.
• Air leakage.
• Cooling-medium leakage.
• Excessive condensate.
• Increased compressor temperature.
• Temperature alarms.
• Reduced compressor efficiency.
• Compressor thermal shutdown.

Maintenance Procedure

1. Shut down the compressor according to the applicable Atlas Copco service procedure.
2. Isolate the electrical supply.
3. Fully depressurize the compressor.
4. Allow the cooler to cool.
5. Isolate the applicable cooling circuit.
6. Inspect the aftercooler for dirt, corrosion, leakage and damage.
7. Remove worn service components.
8. Clean the mating and sealing surfaces.
9. Install the applicable components from 2910563500.
10. Ensure all gaskets/O-rings are correctly seated.
11. Reassemble the aftercooler.
12. Restore the air and cooling circuits.
13. Restart the compressor.
14. Check for leakage.
15. Monitor compressed-air and operating temperatures.

Service Benefits

Using 2910563500 during the appropriate service operation helps:

• Maintain effective aftercooler performance.
• Restore sealing.
• Reduce leakage.
• Maintain suitable compressed-air temperature.
• Support efficient compressor operation.
• Improve compressor reliability.
• Reduce maintenance-related downtime.

Technical Summary

Recommended catalog title:
Atlas Copco 2910563500 – Aftercooler Service Kit / Kit After Cooler (K7), 2910-5635-00.

Note: There is a discrepancy between catalogs: some list 2910563500 simply as “KIT, SERVICE,” while others identify it specifically as an After Cooler Kit (K7). For an exact application, verify the compressor model and serial number before ordering.
