About Spiral Heat Exchangers
SPIRAL HEAT EXCHANGERS were...invented
in the 1930's to cope with the slurries used in the paper making industry that would
constantly plug shell and tube heat exchangers. It was quickly discovered that this type
of heat exchanger was not only resistant to plugging, but also more efficient. Both in
heat transfer characteristics, and physical space. Spiral heat exchangers readily yield a
3 F temperature approach, whether used straight or cross flow. In size, a spiral heat
exchanger can take up less than half the space of a shell and tube design. And less space
needs to be allotted for servicing, since cleaning may only require removing a cover.
