Juan Diaz is the President of the Heat Transfer Research, Inc. (HTRI). He specializes in accounting & finance expertise for Small to Mid-sized Enterprises (SMEs). My passion is to use my experience with international accounting firms and publicly-traded companies to help small & entrepreneurial companies reach the next level so that they can achieve their true potential.

HTRI is the leading source of process heat transfer technology, research, software, and services. Incorporated in 1962, the company conducts studies on heat transfer and fluid flow at a multimillion-dollar testing facility in Navasota, Texas, USA. HTRI technology has been used by companies worldwide for decades to help them design, operate, and maintain heat exchangers and fired heaters.

Based in Navasota, HTRI provides advanced experimental research to the oil and gas, chemical, and petrochemical industries. Our global customer base includes the world’s leading processing companies, engineering contractors, equipment manufacturers, and thermal process consultants. Our acclaimed HTRI Xchanger Suite^® software is considered the most advanced available for the design, rating, and simulation of heat exchangers.

In 1963, all experiments were conducted in Alhambra, California, USA, and administrative offices were located in Bartlesville, Oklahoma, USA. As the company grew in size and reputation, the administrative offices were moved in 1973 to South Pasadena, California.
Over the next fifteen years, we increased international marketing efforts and held the first member meetings in Asia and Europe. In addition to providing research data and analysis, we released our first software products.
