Spiral Heat Exchangers : right solution for slurry, high viscosity fluids containing solids.

Several Heat Transfer applications are involving fluids with fibers (textile), solids (PVC granules, antibiotic broths), high viscosity (visbreaking, tomato juice,) or all of them (waste water treatment, anaerobic digestors, slurry etc.)Selection of proper Heat Exchanger is always a trade off: higher performance but shorter operational life because of fouling or wide gap channel for longer operating cycle but poor thermal performance.

In Pulp & Paper a valid alternative to Shell & Tube was represented by Spiral

Even though in multi pass heat exchangers clogging redirects the flow through the open channels, the channel design in the Spiral Heat Exchangers reduces bypassing through the velocity in the channel that increases until deposits are eliminated

Single channel and design with turbolent flow generate a self cleaning equipment
