SONDEX® spiral heat exchangers

SONDEX® spiral heat exchangers are the ultimate solution for even the most challenging, high-viscosity media. Designed and custom made to handle sludges, slurries, wastewater, wood pulps, hydrocarbons with high viscosity, and fouling liquids that contain fibers and solids. The spiral heat exchangers use coiled metal sheets instead of tube bundles and can achieve very high thermal performance without sacrificing the plate gap that lets the media flow unimpeded.
