Key Benefits & Performance Advantages

Enhanced Compressor Longevity

The COOLER OIL GA90 maintains stable oil temperatures, preventing thermal degradation of the lubricating oil and reducing stress on critical components such as bearings, rotors, and seals. This proactive thermal protection extends the operational lifespan of your GA90 compressor, reducing the frequency of major overhauls and component replacements.

Improved Energy Efficiency

When the oil cooler functions properly, the lubricating oil maintains its optimal viscosity, which reduces internal friction within the compressor element. Efficient cooling improves the overall energy efficiency of the GA90 compressor—comparable systems have demonstrated efficiency gains of up to 8–20% when cooling systems are operating at peak performance.

Reduced Maintenance Costs

By preventing overheating and the associated component wear, this genuine oil cooler contributes directly to lower maintenance requirements. Regular inspection and cleaning of the oil cooler surfaces remain necessary, but a properly functioning cooler significantly reduces the likelihood of costly repairs and unexpected compressor shutdowns.

Consistent Compressor Output

Maintaining stable oil temperatures ensures consistent air delivery and pressure output. Fluctuations in oil temperature caused by an inefficient or failing cooler can lead to unstable compressor performance. The COOLER OIL GA90 eliminates this variable, providing reliable compressed air production for your operations.

High Durability in Harsh Environments

Built with robust materials, this genuine cooler delivers operational stability even in demanding industrial environments with high ambient temperatures, dust, and continuous operation cycles. The GA90 series is designed to perform reliably in ambient temperatures up to 55°C (131°F), and the genuine oil cooler is a critical enabler of this capability.

How the Oil Cooler Protects Your GA90 Compressor

In oil-injected screw compressors, the lubricating oil serves three essential functions: lubrication of moving parts, sealing of the compression chamber, and heat dissipation from the compression process. As air is compressed, heat transfers into the circulating oil. Without proper cooling, oil temperatures rise beyond recommended levels, causing:

• Oil viscosity breakdown, leading to inadequate lubrication
• Accelerated wear of bearings and rotor surfaces
• Premature oil degradation requiring more frequent changes
• Reduced compression efficiency
• Potential compressor shutdown due to high-temperature alarms

The COOLER OIL GA90 directly addresses these risks by transferring heat away from the lubricating oil efficiently. When integrated into the GA90 compressor‘s oil circulation loop, this cooler ensures the oil returns to the compressor element at the correct temperature, preserving its protective and lubricating properties throughout its service life.

Maintenance & Replacement Guidelines

Regular maintenance of the oil cooler is essential for optimal compressor performance. Over time, dust, debris, and contaminants can accumulate on the cooler’s surfaces and fins, reducing its heat dissipation efficiency. The following guidelines are recommended:

• Inspection Frequency: Check the oil cooler during routine compressor servicing every 2,000–4,000 operating hours
• Cleaning: Clean the cooler surfaces using compressed air or appropriate cleaning methods to remove accumulated dust and debris. In very dusty environments, more frequent cleaning may be necessary.
• Leak Inspection: Inspect for any oil seepage around cooler connections and seals. Address any leaks immediately.
• Performance Monitoring: Monitor compressor operating temperatures through the Elektronikon controller. Consistently elevated oil temperatures may indicate reduced cooler efficiency requiring replacement.

When replacement becomes necessary, the COOLER OIL GA90 (Part No. 1625564535) is the direct replacement component. A failing cooler that goes unaddressed can cause oil overheating, reduced efficiency, increased component wear, and potential compressor shutdown.

Installation & Replacement Guidance

Replacement of the oil cooler requires adherence to proper safety procedures. The following steps provide a general overview based on Atlas Copco GA series instruction manuals:

Safety Preparation

1. Stop the compressor completely and switch off the electrical supply voltage
2. Depressurize the system by carefully unscrewing the filler plug (FC1) one turn to allow any residual pressure to escape
3. Allow the compressor to cool down to ambient temperature
4. Drain the oil from the system by removing the designated drain plugs on the air receiver, oil stop valve, check valve, oil cooler, and gearbox

Cooler Replacement

1. Remove the mounting hardware securing the existing oil cooler
2. Disconnect the oil lines from the cooler, noting their positions for correct reconnection
3. Remove the old cooler and inspect the mounting area for any signs of damage or oil residue
