Spiral heat exchangers

Spiral heat exchangers

Exceptionally well-suited for sludges, slurries, waste water, fouling, liquids with high viscosity, and liquids that contain fibers and solids, our SONDEX® spiral heat exchangers are the definitive solution for applications that require treatment of challenging fluids. The design allows for a countercurrent flow that makes it possible to achieve very close temperature approaches.

Since we use coiled metal sheets instead of tube bundles, we can achieve very high thermal performance without sacrificing the channel gap that lets the media flow unimpeded.

The spiral coil itself also contributes to the turbulent flow, and the single-channel design helps alleviate fouling with a “self-cleaning” effect. Accumulated deposits create local increases in velocity, creating a scrubbing effect that is enough to loosen the build-up in fouling in most cases. This allows our SONDEX® spiral heat exchangers to operate in very long sessions without maintenance or cleaning.

Some media, however, are so challenging that the heat exchanger requires more frequent maintenance and cleaning. With this in mind, we have designed hinged covers that are sealed with C-clamps, creating a swing door that is very easy to open and close without any special tools required, letting you access the entire coil for inspection and cleaning.
