Spiral Plate Heat Exchangers

The Spiral Plate Heat Exchangers are made of 2 concentric channels on which spacer pins are welded to form 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 particles for fouling fluids and the pressure drops. These spacer pins facilitate turbulent flow in each channel.

Thanks to its thermal efficiency, its strength and its versatile design, the Spiral Plate Heat Exchanger has proven since 1930 to be essential in fields as various as Refineries, Petrochemical, Oil&Gas or Environment. Key Features and Benefits of Spiral Plate Heat Exchangers are;

Single channel: The single channel flow of our heat exchangers makes it a unique feature in the world.

Self-cleaning effect: Thanks to the single channel configuration, a turbulent flow is created to handle tough medias.As it is a single channel heat exchanger, if there is any cross-section reduction inside the channel, flow velocity will increase flushing out the deposit.

Fouling duties: Originally the spiral plate heat exchanger was mainly used in the pulp and paper industry where fouling problems were frequent when using classical shell and tube exchangers (or multi channels heat exchangers) due to fibers in the effluents.

Tough process conditions: Because of their robust constructionspiral heat exchangers are meant to handle cycling duties. Spiral heat exchangers can expand without mechanical failure when pressured or by increase in temperature.
