Air Cooled, Brazed Aluminum
Combination Air-Cooled Oil Cooler & Compressed Air Aftercooler for Rotary Screw Compressors
The Thermal Transfer Products ACOC/ACOCH Series is a combination air-cooled oil cooler and compressed air aftercooler engineered specifically for rotary screw air compressors. In a single, compact, side-by-side brazed aluminum bar-and-plate core, it handles two jobs at once — cooling compressor lubricating oil and cooling compressed air — so you don’t need separate heat exchangers.
The all-aluminum design is lightweight, corrosion-resistant, and easy to mount, with detachable legs on the ACOC and fixed mounting feet on the ACOCH. That makes the series ideal for converting water-cooled compressor cooling systems to air-cooled, retrofitting existing units in the field, fitting into space-constrained equipment rooms, and mounting in remote locations. Switching from water-cooled to air-cooled cooling eliminates ongoing water and sewer costs and the corrosion and scaling problems common to water-cooled heat exchangers, and the vertical airflow works well for heat-recovery applications.
The ACOC/ACOCH Series includes fifteen models with air flow capacities from 175 to 1,800 SCFM (4.96–50.97 SCMM), sized for rotary screw compressors from 15 to 360 HP (11.2–268.5 kW). Application engineers can help you select and size the right model for your compressor and operating conditions.

Frequently Asked Questions
It’s a combination air-cooled oil cooler and compressed air aftercooler in a single brazed aluminum core, designed for rotary screw air compressors. One unit cools both the compressor’s lube oil and its compressed air.
The units share the same combined-core design; the ACOC ships with detachable mounting legs (unattached), while the ACOCH has fixed mounting feet.
Fifteen models cover flow capacities from 175 to 1,800 SCFM (4.96–50.97 SCMM), sized for compressors from 15 to 360 HP (11.2–268.5 kW).
When you want to eliminate water and sewer costs, avoid corrosion and scaling, convert an existing water-cooled unit to air-cooled, or install in a space-constrained or remote location. The vertical airflow also suits heat-recovery setups.
