Case Study: Graham Hart (Process Technology) Ltd achieves optimized, high‑integrity heat exchanger designs with Aspen Technology's aspenONE Engineering Suite

Graham Hart Delivers Highly Engineered Heat Transfer Equipment with aspenONE Engineering Suite

Graham Hart (Process Technology) Ltd, a UK-based designer and fabricator of highly engineered heat exchangers and pressure vessel systems, faced the challenge of delivering optimized designs that meet stringent performance and safety specifications for critical, high-pressure applications. To ensure accuracy, consistency with client process models, and confidence in performance, Graham Hart uses Aspen Technology’s aspenONE® Engineering Suite—principally the Aspen Exchanger Design & Rating (EDR) suite and Aspen HYSYS®—as core tools in its engineering workflow.

Using Aspen Technology’s Aspen EDR and Aspen HYSYS within aspenONE, Graham Hart standardized thermal modeling, consistent physical properties and automated design optimization, enabling rapid, cost-effective bidding and delivery. The solution helped Graham Hart supply over 2,000 systems, win repeat business from major EPCs and owner-operators, and achieve a measurable 99.4% on-time-in-full (OTIF) delivery rate while securing projects worldwide in Saudi Arabia, China and Egypt.
