Home » Heat exchanger with rotary scraper for high levels of mixing
The R Series heat exchanger from HRS Heat Exchangers, Marietta, Ga., uses a rotary scraper rod capable of reaching velocities of 300 rpm, providing high levels of shear and mixing at the heat transfer surface. This makes it particularly suitable for challenging heat transfer applications, such as those where the product has the potential to crystallize during processing or where aeration is required.
The scraper rod features both a helical mixing spiral (to reduce the pressure drop in the tube) and a series of scraper blades. Together, these provide a continuous scraping action that mixes highly viscous products and reduces fouling.
