The AB Series is engineered for water-cooled aftercooling of hot compressed air or gas. Hot process flow passes through the aftercooler while cooling water absorbs the heat, reducing the discharge temperature before the air enters moisture separation, drying, filtration, storage, or distribution equipment. The compact shell-and-tube construction makes the series well suited for compressor packages, replacement installations, and industrial cooling systems where reliable performance and low pressure drop are priorities.
- Airflow Range: AB Series models are available for compressor capacities from approximately 45 to 3,500 SCFM.
- Pressure Rating: Standard AB Series units are rated for pressures up to 250 PSI.
- Temperature Rating: Designed for inlet temperatures up to 350°F in standard configurations.
- Connection Options: Model-dependent NPT or SAE connections simplify integration into new or existing compressor systems.
- Compressor Applications: Suitable for rotary screw and two-stage reciprocating compressor cooling duties.
- Performance Focus: Shell-and-tube construction provides efficient heat transfer with low compressed-air pressure loss.

Selecting an AB Series Aftercooler
Correct AB Series selection depends on more than compressor horsepower alone. For an accurate recommendation, identify the compressor type, actual airflow, maximum air or gas inlet temperature, operating pressure, cooling-water inlet temperature, available water flow, allowable pressure drop, connection requirements, and the desired compressed-air outlet temperature.
Typical AB Series Uses: Aftercooling for rotary screw compressors, two-stage reciprocating compressors, packaged compressed-air systems, industrial gas cooling, and replacement of existing water-cooled shell-and-tube aftercoolers.
Why Install an AB Series Aftercooler?
- Removes heat from compressed air or gas before downstream treatment and distribution
- Encourages water vapor to condense so it can be removed by a properly sized moisture separator and drain
- Reduces the thermal load placed on refrigerated or desiccant air dryers
- Helps protect filters, valves, piping, tools, instruments, and production equipment
- Provides a compact water-cooled solution when ambient air temperature or ventilation limits air-cooled performance
- Offers multiple AB model sizes and connection configurations for a wide range of compressor capacities
AB Series Sizing Information
When requesting a quote, provide the compressor manufacturer and model, compressor horsepower, SCFM, discharge temperature, operating pressure, cooling-water temperature and flow, and connection preferences. Engineering review is recommended whenever operating conditions approach the unit's maximum pressure or temperature rating, when cooling fluid quality is a concern, or when the application involves a gas other than compressed air.
