The Graham Heliflow Heat Exchanger is uniquely designed and engineered to handle difficult heat transfer applications. Graham created the Heliflow to be exceptionally versatile, yielding heat transfer rates that can be more than 40% better than typical shell and tube designs. The Heliflow Heat Exchanger encompasses a spiral coil, comprised of multiple parallel tubes mounted within a casing. The case/coil construction creates a spiral flow path providing true counterflow. Each application is specially engineered for an optimal balance of thermal and hydraulic requirements, resulting in maximum heat transfer efficiency. High pressure, specialized materials, cyclic operation, temperature extremes and other conditions can be handled without a problem. The Graham Heliflow Heat Exchanger has years of proven service, in thousands of applications throughout the world, with high quality performance always guaranteed.
Advantages
The tubes in the Heliflow are arranged in parallel, starting with an inlet manifold on one end, and terminating at an outlet manifold on the opposite end. The tube bundle is wound into a helical pattern. This coiled construction creates a spiral flow path for the fluid inside the coil.
Each tube is in close contact with the tube above and below it. The coiled tube bundle is fit into a two-piece casing. When the casing is tightened, it is designed to slightly compress the tubes. Because of the tight fit, the shellside fluid is forced to circulate in a spiral pattern created by the open spaces between the coils.
