The HELIXCHANGER^® heat exchanger is a high efficiency heat exchanger and a proprietary product of Lummus Technology Heat Transfer.

HELIXCHANGER heat exchangers increase the capacity and lower maintenance costs for existing plants, and reduce capital investment, plot space and energy costs for grassroots applications. More than 1,800 HELIXCHANGER heat exchangers are in operation worldwide, for varied applications in the oil and gas, refining, petrochemical and chemical industries. The applications range from crude preheat exchangers, feed preheat exchangers in delayed cokers, feed/effluent exchangers in refinery and petrochemical processes, bitumen exchangers in oil-sands, major equipment in ethylene plants to polymer solution coolers in the chemical industry.

In a HELIXCHANGER heat exchanger, quadrant-shaped plate baffles are placed at an angle to the tube axis in a sequential arrangement to create a helical flow pattern. The helical flow offers improved thermal effectiveness, enhanced heat transfer, reduced pressure drop, lower fouling, and significantly reduced vibration hazards.
