Q&A INTERVIEW
ON PLATE HEAT EXCHANGER
late heat exchanger
(PHE) is an important
equipment commonly
used in refineries and
plants. It was invented
by Dr Richard Seligman in 1923 and
soon revolutionized methods of indirect
heating and cooling of fluids without the
usage of electricity. Also called plate and
frame heat exchanger, it functions by
simply transferring heat from one fluid to
another through the use of metal plates.
Comparing it with other conventional
heat exchangers such as shell and tube
heat exchanger or spiral heat exchanger,
PHE is favored mainly because the fluids
work on larger surface areas and are
capable of dispersing on the metal plates,
thus greatly increases the speed of
