Concentrated (or dense) slurries are found in a wide range of natural and synthetic materials and processes. A dense slurry or suspension is a combination of particles of one material spread throughout a second phase, with the particles being large enough to be seen with the naked eye or a magnifying glass.

The addition of suspended particles to a fluid raises its viscosity. Slurries having a higher concentration/volume fraction will have higher viscosity.

During the production process, industries experience fouling challenges while heating or cooling concentrated or dense suspensions fluid. When solid particles suspended in the process stream deposit on the heat transfer surface, this may have an impact on product specifications.

The KLAREN self-cleaning heat exchanger technology has proven to be effective in a variety of systems dealing with dense/concentrated slurries (Eg. Paint, plastic, food, coatings etc). We can correctly analyze the rheology of the slurry to create an efficient self-cleaning system.
