Custom Air Cooled Heat Exchangers: Design & Manufacture

We utilise a dual-engineering approach. Thermally, we use advanced modelling and simulation software to ensure the most efficient heat transfer for your specific fluid properties. Mechanically, we account for complex variables including wind loading, structural support calculations and nozzle loads to API 661. Our fan selections (Forced or Induced Draft) are tailored to balance power consumption (OPEX) with noise limits and process stability.

The challenge with air-cooled heat exchangers isn't just the thermal duty; it’s the environment. Fluctuating ambient air temperatures, cross-winds and noise restrictions in sensitive areas can often compromise standard "off-the-shelf" units.

At Graham Hart Process Technology, we move beyond standard fabrication. We address the "Why" behind your process needs. For instance, if you are operating in a hydrogen service, we provide fully welded headers to ensure leak-free integrity. If you are dealing with high-fouling fluids, we design removable cover plates to simplify maintenance. By integrating site-specific data—such as wind loading and noise sensitivity—into our fan selection, we deliver a unit that is not only thermally efficient but operationally robust.
