Atlas Copco Cooler Kit Replacement – 2901186700

Atlas Copco 2901186700 – Cooler Kit

The Atlas Copco 2901186700 (2901-1867-00) Cooler Kit is a service and maintenance kit designed for compatible stationary oil-free ZR/ZT compressors. Atlas Copco specifically identifies the kit for ZT55 applications. Its purpose is to restore the sealing and vibration-isolation components associated with the compressor cooler assembly.

Working Process:

During normal compressor operation, the cooler assembly is subjected to continuous airflow, temperature changes, vibration, pressure fluctuations and repeated compressor operating cycles.

The cooler transfers heat away from the applicable compressor circuit, helping maintain operating temperatures within the required range. Effective heat transfer is important for maintaining compressor reliability and protecting downstream and internal components from excessive thermal stress.

The 2901186700 Cooler Kit provides replacement service components used to maintain the cooler assembly. Atlas Copco’s official catalog lists the kit weight as 254 g and specifies the following components:

• Seal – 1 pc
• Vibration Damper – 2 pcs
• Vibration Damper – 4 pcs
• O-ring 64.5 × 3 – 2 pcs
• Instruction – 1 pc

The sealing component helps maintain a leak-resistant connection between the cooler and its mating components.

The O-rings provide sealing around the applicable cooler connections. They prevent unwanted air or fluid leakage and help maintain the intended operating pressure and flow conditions.

The vibration dampers isolate the cooler assembly from compressor vibration. They reduce the transmission of mechanical vibration between the cooler and compressor structure and help protect the cooler and its connections from excessive mechanical stress.

During normal operation, vibration dampers gradually experience compression, movement, temperature variations and mechanical fatigue. Over time, they may harden, crack, deform or lose their ability to isolate vibration effectively.

Similarly, O-rings and seals can lose elasticity due to temperature, age and exposure to the operating environment. A deteriorated seal can cause leakage and reduce system reliability.

If the cooler mounting dampers become worn, excessive vibration can be transmitted to the cooler assembly. This may lead to loose connections, mechanical fatigue, abnormal noise or premature failure of associated components.

If an O-ring or seal deteriorates, leakage can occur at the cooler interface. Even a small leak can affect system performance and may eventually result in more serious component damage.

Maintenance Procedure:

Before servicing the cooler assembly, the compressor must be stopped, electrically isolated, depressurized where applicable, and allowed to cool according to the applicable Atlas Copco safety procedure.

The cooler should be inspected for contamination, corrosion, leakage, damaged connections, loose mounting points and excessive vibration.

The existing seals and O-rings should be removed carefully without damaging the mating surfaces.

The supplied 2901186700 Cooler Kit should be used to replace the applicable sealing and vibration-isolation components.

All sealing surfaces must be clean and free from dirt, old sealing material and foreign particles.

The supplied O-rings must be installed in their correct grooves without twisting, cutting, overstretching or pinching.

The vibration dampers must be installed in their correct positions and orientations so that the cooler is properly supported and isolated from compressor vibration.

The supplied seal must also be installed correctly according to the applicable Atlas Copco service procedure.

After assembly, all cooler connections and mounting points should be inspected for correct installation.

The compressor should then be restarted and monitored for leakage, abnormal vibration, noise and operating temperature.

The cooler should remain securely mounted while the vibration dampers isolate the cooler from excessive mechanical vibration.

Correct sealing and vibration isolation help maintain reliable cooler operation and reduce the possibility of premature mechanical failure.

Using the Atlas Copco 2901186700 Cooler Kit during the appropriate maintenance operation helps restore sealing, vibration isolation and mechanical reliability of the cooler assembly.
