Atlas Copco 1092005069 Oil Cooler Heat Exchanger (YL12.9-00)
1092005069 Oil Cooler
Product Description
The Atlas Copco 1092005069 is the oil cooler that keeps lubricant inside an oil-injected screw compressor within its working temperature band. Atlas Copco lists it as COOLER OIL, with the internal type code YL12.9-00. Hot oil leaves the compression element and enters this heat exchanger. A fan-driven air stream removes heat before the oil returns to the circuit. The number 1092005069 identifies the genuine unit built to the original thermal and pressure specification.
An oil cooler looks simple, yet it protects the most expensive parts of the machine. Compressing air generates heat, and that heat travels straight into the lubricant. Left unchecked, the oil thins, the film between moving surfaces breaks down, and the element wears faster than its service life allows.
About 1092005069
About the 1092005069 Oil Cooler
This cooler works as an oil-to-air heat exchanger. Warm lubricant flows through the tube or plate core while ambient air passes across the external fins. The metal wall carries heat from oil to air without letting the two fluids mix. A driven fan sets the air speed, so cooling tracks the load the compressor is running at that moment.

Installation and Maintenance
Several signs point to a cooler past its useful life. Oil temperature climbs toward the alarm while the load has not changed. Discharge temperature follows the same path. Oil weeps from the core seam, or the fin pack stays clogged after a proper clean.
Cleaning solves fouling on the air side, and that is the first step on any warm-oil complaint. Internal tube corrosion or a cracked core will not respond to cleaning, and those faults only grow. At that point a fresh 1092005069 restores the original cooling capacity and brings oil temperature back to design.
Replace on the compressor's stated interval where one exists, because the core wears at a known rate. Fitting the genuine part keeps the pressure rating and the dimensions the package was built around. The bracket, hoses, and fan shroud then line up without modification.
FAQ
Order the 1092005069 as the direct replacement for a worn or leaking oil cooler. Send your nameplate and serial number so we can confirm the match. We then ship the genuine Atlas Copco unit built to the original YL12.9-00 specification.
