The Forced Circulation Evaporators are made for use in the various industries. The Forced circulation occurs when hydrostatic head prevents boiling at the heating surface. Common uses of evaporators include waste streams, crystallizers, viscous fluids, and other difficult process fluids as suppressed boiling can reduce scaling and fouling. It utilizes a circulation pump to create a large circulation stream, and a pressure-reducing device to allow for flashing of the hot circulating stream. The Forced Circulation Evaporators are very durable.
