Used Air Cooled Heat Exchangers in Illinois, USA

Overview

Air-cooled heat exchangers transfer heat from process fluids or gases to ambient air using finned tubes and axial or centrifugal fans. Common in power generation, compressors, engines, and petrochemical plants, they eliminate the need for cooling water and are suitable for remote or arid sites. Selection hinges on thermal duty, airflow, materials, fouling tolerance and corrosion resistance, plus accessibility for cleaning and maintenance.

FAQ

What should I check when buying a used air-cooled heat exchanger?

Verify thermal duty (heat load, flow rates, inlet/outlet temps), mechanical condition of fins/tubes, fan and motor health, structural integrity, corrosion or leaks, materials compatibility, and available documentation like drawings and test certificates.

How do I prepare an air-cooled exchanger for shipping?

Drain and purge fluids, secure or remove fans and loose piping, brace tubes and bundles, protect fins from bending, mount on a rigid skid, label lifting points, and use a carrier experienced with oversized industrial equipment.

What regular maintenance keeps performance optimal?

Schedule periodic fin/tube cleaning, inspect and lubricate fan bearings, check fan motors and belts, test for air blockages, monitor pressure drop and outlet temperatures, perform corrosion inspections, and plan annual performance tests and mechanical reviews.
