An improved method of heat transfer between a first substantially homogenous fluid passing through the inside of a heat exchange tube, and a second fluid on the outside of the heat exchange tube includes the step of passing the first fluid through a compound turbulator inside the tube. The compound turbulator includes a twisted strip surrounded by a helical coil that is closely spaced from the walls of the tube. Passing the first fluid over the compound turbulator generates a high level of turbulence in the first fluid in the region adjacent the tube wall, facilitating heat transfer to the second fluid on the outside of the heat exchange tube. The augmentation of heat transfer to the second fluid can also be accomplished through the use of a helical coil installed on the outside of the tube.
