Heat Transfer Division


The Heat Transfer Division (HTD) provides custom engineered equipment such as tubular heat exchangers and pressure vessels for the power generation, petro-chemical and chemical industries. The main focus of HTD’s business concentration is the large and complex heat transfer equipment essential to the operation of a power plant. Prominent among such capital equipment are main steam surface condensers, feed water heaters, component coolers, steam generators, moisture separator re-heaters and auxiliary heat exchangers used in the nuclear, solar and fossil power and steam supply systems.

From its early focus on fossil fueled power plant equipment, HTD has grown its offerings to in this century to include renewable energy plants. HTD is implementing Holtec International’s belief that the company can play a vital role in the emerging technologies for coaxing electric power from the sun. Holtec is collaborating with other major players in the solar energy industry to make solar power a viable energy generation technology. Other areas of HTD’s endeavors include heat exchange equipment for geothermal, petro-chemical and chemical plants.

Technology Leadership

The key to HTD’s success is its internationally recognized expertise in developing innovative heat exchanger designs backed by precision and quality fabrication. Indeed, when it comes to heat exchangers, Holtec engineers have, proverbially speaking, “written the book”. The book, “Mechanical Design of Heat Exchangers and Pressure Vessels”, by Dr. Kris Singh and Dr. Alan Soler of Holtec International (Arcturus Publishers, 1984) is, even to this day, the only book on this subject in the English language.

Over the past four decades, Holtec engineers have helped shape the ASME codes and national consensus standards such as the TEMA Standards (a consensus standard for commercial heat exchangers), HEI Standards for nuclear heat exchangers and surface condensers, feed water heaters and air cooled condensers.

Several of Holtec’s engineers are globally recognized experts on heat exchanger design. Working with the company’s Nuclear Power Division (NPD), HTD provides unique expertise in designing unconventional heat exchangers such as those used in space, cryogenic, and high-energy (blast and impact) environments.

Holtec engineers have published over one hundred technical papers on heat exchanger design and analysis, most of them in the permanent literature. These Holtec papers have significantly influenced the development of heat exchanger methodologies in the US and overseas.
