Heat Exchange Institute (HEI)

IHS Markit is your source for HEI standards and publications.

The Heat Exchange Institute (HEI) is a non-profit trade association committed to the technical advancement, promotion, and understanding of a broad range of utility and industrial-scale heat exchange and vacuum apparatus. HEI concentrates its efforts on the manufacturing and engineering aspects of air cooled condensers, steam surface condensers, closed feedwater heaters, shell and tube heat exchangers, plate heat exchangers, liquid ring vacuum pumps, steam jet ejectors and deaerators.

The primary purpose of HEI is to develop and publish standards which advance the technology, increase the efficiency, and promote the use of heat exchange and vacuum apparatus.

This objective is accomplished through technology-specific committees operating under the authority of the Institute's seven Sections:

  1. Air Cooled Condensers
  2. Steam Surface Condensers
  3. Closed Feedwater Heaters
  4. Shell & Tube Heat Exchangers
  5. Plate Heat Exchangers
  6. Vacuum Technology
  7. Deaerator

Each of these sections sponsors a technical committee which is charged with developing and revising standards specific to its range of products.
