Welcome to the Heat Exchange Institute Website.

Organized in 1933, primarily as a steam condenser organization, the Heat Exchange Institute’s (HEI) early efforts were concentrated on developing and publishing heat transfer data. These efforts evolved into agreements with a well-known university to develop calorimeter testing procedures that would develop test data and correlate this with actual field operating data. The information generated was used to develop and publish product standards.

Subsequently, the membership of the Feedwater Heater Manufacturers Association transferred to HEI forming a Section within the institute. The Vacuum Technology Section was added later to address steam jet ejectors and vacuum apparatus, including liquid ring vacuum pumps. A Power Plant Heat Exchanger Section and a Deaerator Section were also added to meet the needs of these segments of the industry. Just recently, an Air Cooled Condenser Section and a Plate Heat Exchanger Section have been added to the Institute, and the name of the Power Plant Heat Exchanger Section has been changed to Shell & Tube Heat Exchanger Section to better reflect the equipment that is addressed in its standard.

Today, the Institute’s membership comprises major North American manufacturers of heat transfer equipment and vacuum apparatus. These companies address the need for industry standards which reflect the evolution of technology.

The HEI is acknowledged worldwide as the leading standards development organization for heat exchange and vacuum apparatus. The HEI maintains its commitment to the technical advancement of the industry it serves. Constantly addressing change in technology, the HEI retains its flexibility to expand its existing sections or form new sections, depending on the needs of the industry and its member companies.
