The Spiral Plate Heat Exchanger or SPHE is a welded heat exchanger, single channel, used since 1930, and its efficiency is all over the world well known.
The Spiral Plate Heat Exchanger is made of 2 concentric channels on which spacer pins are welded to make the channel's gaps. Each channel gap and the width of the channels are selected to meet each Customer's specific requirement and working conditions. It permits to take into account the flow rates, the sizes of the particules for fouling fluids and the pressure drops. These spacer pins facilitate turbulent flow in each channel
At the beginning, the Spiral Plate Heat Exchanger has been mainly used in the pulp and paper industry, where there were frequent fouling problems with the classical shell and tubes (or multi channels heat exchangers) due to fibers in the effluents.
During these last 20 years, the Spiral Plate Heat Exchanger has become essential in fields as various as Refineries, Oil & Gas, Petrochemical, or Environnement... thanks to its thermal efficiency, its strength and its versatile design.
Able to work in extreme conditions (of pressure and temperature), this single channel heat exchanger, with self-cleaning effect, has become the alternative to the shell & tube exchangers.
More compact, and until 3 times more thermally efficient, the Spiral Plate Heat Exchanger gives the possibility to do substantial savings in installation, operation and maintenance.
