Plate Combi Oil & Air Cooler 1613950800 Replacement Heat Exchanger

1. Product Overview

Part Number: 1613950800 Product Name: Dual Function Plate Oil Cooler & Air Aftercooler (Combi Cooler) Matching Brand: Atlas Copco Oil-Injected Screw Air Compressors Applicable Series: GA medium & large screw compressor series Core Structure: Vacuum brazed aluminum plate-fin combi heat exchanger Function: Simultaneously cool lubricating oil and discharged compressed air

This 1613950800 combi cooler is the core thermal control component for Atlas Copco GA series screw compressors. During continuous compression operation, high-temperature lubricant oil and hot compressed air pass through separate internal flow channels inside the cooler core. The aluminum fin structure rapidly transfers heat to ambient airflow to lower oil and air temperature, preventing oil degradation, airend overheating and high-temperature safety trips. Our aftermarket cooler strictly meets OEM dimensional and performance standards, offering stable long-term cooling performance at a cost-effective price.

3. Main Advantages

1. Integrated Dual-Circuit Combi Structure Separate independent flow channels for oil and compressed air, realize oil cooling and air aftercooling in one unit, greatly simplify compressor pipeline layout and save equipment space.

2. Super High Heat Dissipation Efficiency Optimized multi-layer fin layout enlarges heat exchange area, heat transfer efficiency far exceeds traditional tube-and-fin coolers, stable cooling effect even in high-temperature summer workshop environment.

3. Zero Leakage Vacuum Brazing Technology All internal plates and fins are fused by high-temperature vacuum brazing, no rubber gaskets or loose welding seams, avoid oil & air leakage caused by aging or vibration.

4. Strong Anti-Aging & Anti-Corrosion Performance Whole surface treated with anti-oxidation black coating, resistant to mineral/compressor synthetic oil, humid air, dust and weak acid condensate, suitable for harsh mining, chemical and coastal factories.

5. Direct OEM Replacement, Low Maintenance Cost Fully consistent with original installation size, ports and mounting brackets; no extra accessories needed during replacement. Effectively solve common cooler faults like insufficient cooling, internal blockage and oil leakage, extend service life of airend, oil separator and bearings.

4. Common Faults Solved by This Cooler

· Compressor oil temperature too high, frequent high-temperature alarm shutdown

· Exhaust compressed air temperature exceeds standard, affecting dryer & filter service life

· Original cooler internal blockage, heat dissipation capacity drops sharply

· Cooler joint oil leakage, air leakage leading to pressure loss

· Excessive carbon deposition inside oil circuit caused by long-term high oil temperature

5. Application Scenarios

Industrial production workshops, automobile manufacturing, mining, chemical processing, textile printing, food processing, construction machinery and all factories equipped with Atlas Copco GA series screw air compressors.
