Every A. H. Lundberg Associates, Inc. flooded forced circulation concentrator and heavy liquor heater is offered with the Reynolds Enhanced Heat Transfer (REX) technology. The technology reduces the horsepower consumption of the units by as much as 45% over conventional technology while at the same time improving resistance to fouling and scaling.

The REX technology consists of installing spiral inserts within each tube of the heat exchanger. The helical insert imparts a swirl to the liquor at lower velocities thereby increasing shear at the tube wall and increasing the heat transfer rate in viscous fluids.

The end result of the REX technology is reduced pressure drop across the flooded heat exchanger that in turn greatly reduces operating horsepower and cost. A further benefit is the superior run time between cleanings of a unit.

The REX technology can easily be retrofitted into existing flooded forced circulation concentrators and heavy liquor heaters.
