Exclusive, state-of-the-art design. A unique design that makes HELIFLOW Heat Exchangers exceptionally compact, strong, efficient, reliable, versatile, and able to handle a wide range of flow, pressure and temperature requirements. They have had years of proven service in thousands of applications throughout the world, with high quality performance always guaranteed.
Simplicity. The Heliflow encompasses a spiral coil, comprised of multiple parallel tubes mounted within a casing and baseplate. The case/coil construction creates a spiral flow path for both the fluid inside and outside of the tube coil, providing true counterflow.
An accurate, constant velocity is maintained. Coil spacing between tubes may be varied for an optimal balance of thermal and hydraulic requirements. This provides maximum, more consistent heat transfer efficiency.
