The HTRI Design Manual is a multi-volume technical compendium. It translates decades of empirical laboratory research into practical engineering workflows. Process engineers, mechanical engineers, and manufacturers rely on it to design and verify heat transfer equipment.
Your employer or university must pay for membership. Once approved, you gain access to the entire HTRI documentation library, including:
To understand the math behind the software, refer to classics such as: Htri Design Manual Pdf 123
for mechanical design. It is a vital resource for process engineers to perform sensitivity analyses—varying parameters like tube diameter or baffle spacing—to achieve an optimized, cost-effective design that meets permissible pressure drop limits.

The manual acts as a bridge between pure thermal science and rigid mechanical design codes. It cross-references and ensures compliance with global standards, including (Tubular Exchanger Manufacturers Association) dimensional standards, ASME Section VIII pressure vessel safety requirements, and API 660 / API 661 oil and gas refining configurations.
Over the decades, the HTRI team conducted thousands of experiments on industrial-scale equipment to see exactly how fluids boil, condense, and flow. They turned these real-world "stories" of fluid behavior into the HTRI Design Manual Your employer or university must pay for membership
: When HTRI software flags an error—such as high vibration risk or acoustic resonance—the manual provides the underlying scientific background needed to resolve the issue.
The manual distinguishes between friction factors for:
