Spiral Heat Exchangers

Spiral heat exchangers are manufactured using two metal plates wound together leaving two parallel channels where fluids can flow in a counter-current direction. They offer excellent thermal approaches but are best suited for high fouling fluids like slurries or fluids containing fibrous material.  

Unique and Reliable Design

Spiral heat exchangers, present in various applications for almost a century, have proven to be the most efficient and reliable solution for handling fluids containing fibres and suspended particles. Optimum flow speeds can be set by selecting the most suitable spiral channel width, which permits remarkably high heat transfer.

Self Cleaning

Single flow channel combined with turbulent flow allows self cleaning of the spiral heat exchanger. When fouling is deposited in the channel, the flow does not find alternative pathways. Instead, the cross-sectional flow area is reduced and the local velocity increases, scrubbing deposits and fouling. This self cleaning ability increases the operational uptime of the heat exchanger and interval between maintenance. 

Easy Maintenance and Easy Access

Spirals can be designed with removable covers equipped with davits making for easy inspection and pressure washing. 

Energy Saving

Fully counter current flow circulation (Type 1 Spirals) is able to exchange heat even with close temperature approach and temperature cross flows - heat recovery is possible!

Compact

High performance and compact structure results in very space saving equipment.
