In applications prone to high fouling, consider using a spiral heat exchanger. Its single-channel design minimizes fouling and erosion and helps ensure high flow velocities even with heavy process slurries.
A spiral heat exchanger is a useful alternative to shell and tube designs for many applications prone to fouling and plugging problems. For more than 60 years, it has been used in difficult services ranging from PVC slurry coolers to asphalt heaters. Its flow-channel geometry and single-channel design induce highly turbulent flow, so the compact exchanger can operate reliably with low fouling rates even in heavy fouling, fibrous or slurry duties. It can be opened quickly and easily for inspection, cleaning and maintenance.
