Founded in January 1972, PFR Engineering Systems provides thermal engineering services to the energy sector, focusing on software-based simulation of equipment used in oil and petrochemical operations. Its early work included tools to model air‑cooled heat exchangers and fired heaters, furnaces, and boilers, and it has since expanded the scope of its simulations. Based in Santa Fe Springs, California, the company is a small, wholly owned subsidiary that maintains independent operations.

PFR serves customers across the oil and petrochemical industries, including major manufacturers, EPCs, and oil companies worldwide, by delivering simulation software used for fired heater and furnace rating. The firm’s offerings evolved from mainframe solutions to desktop PC platforms, broadening access for engineers and designers. In May 2025, PFR released a new version of its PC-based simulation software, signaling ongoing updates to its core tools.
