Temperature extremes

Graham Heliflow Heat Exchanger
High (or low) temperature fluids will cause the tube material to expand (or contract). This thermal expansion will create high stresses at the tube-to-tubesheet joints of standard straight shell and tube type units. The Heliflow heat exchanger, with its spring-like coils, allows movement of the coil within the bundle. This feature allows the Heliflow to easily withstand temperature differences of over 500 degrees F between fluids. Cyclic operation and extreme temperatures are easily handled.
