Don‘t wait until your GA90 compressor shuts down due to overheating. Invest in the genuine COOLER OIL GA90 today and keep your production running smoothly and efficiently.
The Atlas Copco 1625564535 (=1625594505) COOLER OIL GA90 is a vital component designed specifically for the GA90 series oil-injected rotary screw air compressors. This genuine cooling unit ensures your compressor operates within optimal temperature ranges, preventing overheating and maintaining consistent performance even under demanding industrial conditions. Manufactured by Atlas Copco in India, this 100% brand-new genuine product is sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd., we guaranteeing authenticity and uncompromised quality.

The Atlas Copco COOLER OIL GA90 is a high-performance cooling unit engineered to dissipate heat from the lubricating oil circulating within the GA90 screw compressor. As oil-injected screw compressors generate significant thermal load during continuous operation, maintaining proper oil temperature is essential for preserving oil viscosity, ensuring effective lubrication, and preventing thermal degradation of critical internal components.
This cooler serves as the thermal management backbone of the GA90 compressor system, delivering consistent heat dissipation that directly translates into longer equipment lifespan, fewer unexpected breakdowns, and lower overall operating costs. Designed by Atlas Copco‘s engineering team specifically for the GA90 platform, this genuine cooler meets the same stringent quality standards as the original equipment.
Atlas Copco GA90 compressors feature oversized oil coolers specifically engineered for tropical climates to prevent thermal shocks and maintain stable operation in ambient temperatures up to 55°C (131°F). The COOLER OIL GA90 plays an integral role in this robust thermal management system.
Selecting genuine Atlas Copco components is not merely a recommendation—it is a strategic decision that protects your compressor investment. Here is why this genuine oil cooler stands out:
Guaranteed Performance & Reliability
Genuine Atlas Copco parts are designed in-house and thoroughly tested to deliver the reliability, long lifetime, and energy efficiency you expect from your equipment. Unlike general-purpose alternatives that must fit multiple machine types, this oil cooler is built to exact Atlas Copco specifications for perfect fit and function within the GA90 compressor system.
Protection Against Costly Failures
Counterfeit or substandard cooling components compromise mechanical integrity and can lead to premature compressor failures. Genuine Atlas Copco parts protect your compressor from avoidable breakdowns and maintain the validity of your equipment’s warranty coverage.
Long-Term Cost Efficiency
Using original Atlas Copco parts ensures your compressor runs at its highest efficiency level, reduces energy consumption, and extends service intervals. The initial investment in genuine parts pays for itself through reduced downtime, lower maintenance frequency, and extended equipment service life.
Verifiable Authenticity
The genuine COOLER OIL GA90 supplied by us includes full traceability through Atlas Copco‘s supply chain. Each part is sourced from Atlas Copco (Shanghai) Trading Co., Ltd., ensuring complete authenticity and compliance with Atlas Copco’s quality standards.

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.
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.
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.
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.
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.

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:
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.
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:
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.

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:
Important: Replacement of the oil cooler should be performed by qualified service personnel following the complete Atlas Copco GA90 instruction manual procedures. Always consult the official instruction book and comply with all safety regulations during maintenance activities.

David Chen –
Will definitely order from Sekes again.
We replaced our failing oil cooler with this genuine 1625564535 unit. The difference in compressor performance was noticeable right away—lower operating temperatures and quieter running. ACD provided great support and the part was exactly as described, brand new genuine Atlas Copco product.
Robert Martinez –
Very satisfied with this purchase.
The COOLER OIL GA90 arrived well-packaged with all proper Atlas Copco labeling and documentation. Installation was straightforward and the cooler has been running reliably for two months now with zero temperature issues. Good price, genuine product, and smooth transaction. Thanks to ACD for the professional service.
Mark Thompson –
Highly recommend this supplier for Atlas Copco genuine parts.
Ordered the COOLER OIL GA90 for our GA90 compressor that kept overheating. This genuine part arrived quickly from ACD. Installed it last week and our compressor temperatures dropped back to normal range immediately. Excellent product, perfect fit, no issues at all.
